{"nessus": [{"lastseen": "2023-05-18T15:02:36", "description": "According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :\n\n - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system:\n memory allocation, process allocation, device input and output, etc.Security Fix(es):In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/ net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls.(CVE-2020-10942)In the Linux kernel 5.0.21, a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call.(CVE-2019-19319)In kernel/compat.c in the Linux kernel before 3.17, as used in Google Chrome OS and other products, there is a possible out-of-bounds read. restart_syscall uses uninitialized data when restarting compat_sys_nanosleep. NOTE: this is disputed because the code path is unreachable.(CVE-2014-3180)In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-buffer).(CVE-2019-19768)There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c.(CVE-2020-8647)There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c.(CVE-2020-8649)drivers/g pu/drm/radeon/radeon_display.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. NOTE: A third-party software maintainer states that the work queue allocation is happening during device initialization, which for a graphics card occurs during boot. It is not attacker controllable and OOM at that time is highly unlikely.(CVE-2019-16230)There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the n_tty_receive_buf_common function in drivers/tty/ n_tty.c.(CVE-2020-8648)A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest.(CVE-2020-2732)An issue was discovered in the Linux kernel through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2.(CVE-2020-9383)ext4_protect_reserved_i node in fs/ext4/block_validity.c in the Linux kernel through 5.5.3 allows attackers to cause a denial of service (soft lockup) via a crafted journal size.(CVE-2020-8992)Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients.(CVE-2017-13080)Linux Kernel version 3.18 to 4.16 incorrectly handles an SG_IO ioctl on /dev/sg0 with dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte cmdp. This may lead to copying up to 1000 kernel heap pages to the userspace. This has been fixed upstream in https://github.com/torvalds/linux/commit/a45b599ad808c3 c982fdcdc12b0b8611c2f92824 already. The problem has limited scope, as users don't usually have permissions to access SCSI devices. On the other hand, e.g. the Nero user manual suggests doing `chmod o+r+w /dev/sg*` to make the devices accessible. NOTE: third parties dispute the relevance of this report, noting that the requirement for an attacker to have both the CAP_SYS_ADMIN and CAP_SYS_RAWIO capabilities makes it 'virtually impossible to exploit.'(CVE-2018-1000204)The Linux kernel through 5.3.13 has a start_offset+size Integer Overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allows local users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation.(CVE-2019-18675)arch/x86/kvm/emulate.c in the Linux kernel before 4.8.12 does not properly initialize Code Segment (CS) in certain error cases, which allows local users to obtain sensitive information from kernel stack memory via a crafted application.(CVE-2016-9756)Double free vulnerability in drivers/ net/usb/cdc_ncm.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (system crash) or possibly have unspecified other impact by inserting a USB device with an invalid USB descriptor.(CVE-2016-3951)Linux Kernel contains an out-of-bounds read flaw in the asn1_ber_decoder() function in lib/asn1_decoder.c that is triggered when decoding ASN.1 data. This may allow a remote attacker to disclose potentially sensitive memory contents.(CVE-2018-9383)Linux Kernel contains a flaw in the ip6_setup_cork() function in net/ipv6/ip6_output.c that is triggered when handling too small IPv6 MTU sizes. This may allow a local attacker to cause a crash or potentially gain elevated privileges.(CVE-2018-9389)In the Android kernel in the video driver there is a use after free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.(CVE-2019-9458)An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use this flaw to crash the system, resulting in a denial of service.(CVE-2019-19332)kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words, although this slice expiration would typically be seen with benign workloads, it is possible that an attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray requests. An attack does not affect the stability of the kernel it only causes mismanagement of application execution.)(CVE-2019-19922)An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.(CVE-2019-5108)A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.(CVE-2019-14896)A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA.(CVE-2019-14897)In the Linux kernel through 5.4.6, there is a NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition, aka CID-f70267f379b5.(CVE-2019-19965)In the Linux kernel before 5.1.6, there is a use-after-free in cpia2_exit() in drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service, aka CID-dea37a972655.(CVE-2019-19966)In the Linux kernel before 5.1, there is a memory leak in\n __feat_register_sp() in net/dccp/feat.c, which may cause denial of service, aka CID-1d3ff0950e2b.(CVE-2019-20096)In the Linux kernel before 5.0.6, there is a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c, related to put_links, aka CID-23da9588037e.(CVE-2019-20054)drivers/ net/usb/pegasus.c in the Linux kernel 4.9.x before 4.9.11 interacts incorrectly with the CONFIG_VMAP_STACK option, which allows local users to cause a denial of service (system crash or memory corruption) or possibly have unspecified other impact by leveraging use of more than one virtual page for a DMA scatterlist.(CVE-2017-8068)A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver.\n The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code.(CVE-2019-14895)The acpi_ds_create_operands() function in drivers/acpi/acpica/dsutils.c in the Linux kernel through 4.12.9 does not flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.(CVE-2017-13693)Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory entry lists.(CVE-2019-10220)A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system.(CVE-2019-14901)In the AppleTalk subsystem in the Linux kernel before 5.1, there is a potential NULL pointer dereference because register_snap_client may return NULL. This will lead to denial of service in net/appletalk/aarp.c and net/appletalk/ddp.c, as demonstrated by unregister_snap_client, aka CID-9804501fa122.(CVE-2019-19227)In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/class/cdc-acm.c driver, aka CID-c52873e5a1ef.(CVE-2019-19530)In the Linux kernel before 5.3.9, there are multiple out-of-bounds write bugs that can be caused by a malicious USB device in the Linux kernel HID drivers, aka CID-d9d4b1e46d95.\n This affects drivers/hid/hid-axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c, drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c, drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c, drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c, drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid-tmff.c, and drivers/hid/hid-zpff.c.(CVE-2019-19532)A use-after-free in binder.c allows an elevation of privilege from an application to the Linux Kernel. No user interaction is required to exploit this vulnerability, however exploitation does require either the installation of a malicious local application or a separate vulnerability in a network facing application.Product: AndroidAndroid ID: A-141720095(CVE-2019-2215)The do_remount function in fs/ namespace.c in the Linux kernel through 3.16.1 does not maintain the MNT_LOCK_READONLY bit across a remount of a bind mount, which allows local users to bypass an intended read-only restriction and defeat certain sandbox protection mechanisms via a 'mount -o remount' command within a user namespace.(CVE-2014-5206)Multiple integer overflows in the lzo1x_decompress_safe function in lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor in the Linux kernel before 3.15.2 allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Literal Run.\n NOTE: the author of the LZO algorithms says 'the Linux kernel is *not* affected media hype.'(CVE-2014-4608)The pivot_root implementation in fs/ namespace.c in the Linux kernel through 3.17 does not properly interact with certain locations of a chroot directory, which allows local users to cause a denial of service (mount-tree loop) via . (dot) values in both arguments to the pivot_root system call.(CVE-2014-7970)A security flaw was discovered in nl80211_set_rekey_data() function in the Linux kernel since v3.1-rc1 through v4.13. This function does not check whether the required attributes are present in a netlink request.\n This request can be issued by a user with CAP_NET_ADMIN privilege and may result in NULL dereference and a system crash.(CVE-2017-12153)arch/x86/kernel/entry_32.S in the Linux kernel through 3.15.1 on 32-bit x86 platforms, when syscall auditing is enabled and the sep CPU feature flag is set, allows local users to cause a denial of service (OOPS and system crash) via an invalid syscall number, as demonstrated by number 1000.(CVE-2014-4508)fs/ namespace.c in the Linux kernel through 3.16.1 does not properly restrict clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and changing MNT_ATIME_MASK during a remount of a bind mount, which allows local users to gain privileges, interfere with backups and auditing on systems that had atime enabled, or cause a denial of service (excessive filesystem updating) on systems that had atime disabled via a 'mount -o remount' command within a user namespace.(CVE-2014-5207)In the Linux kernel before 5.3.7, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/adutux.c driver, aka CID-44efc269db79.(CVE-2019-19523)In the Linux kernel before 5.3.12, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/input/ff-memless.c driver, aka CID-fa3a5a1880c9.(CVE-2019-19524)In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/hid/usbhid/hiddev.c driver, aka CID-9c09b214f30e.(CVE-2019-19527)In the Linux kernel before 5.3.7, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/iowarrior.c driver, aka CID-edc4746f253d.(CVE-2019-19528)In the Linux kernel before 5.2.9, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/yurex.c driver, aka CID-fc05481b2fca.(CVE-2019-19531)In the Linux kernel before 5.3.4, there is an info-leak bug that can be caused by a malicious USB device in the drivers/media/usb/ttusb-dec/ttusb_dec.c driver, aka CID-a10feaf8c464.(CVE-2019-19533)In the Linux kernel before 5.3.11, there is an info-leak bug that can be caused by a malicious USB device in the drivers/ net/can/usb/peak_usb/pcan_usb_core.c driver, aka CID-f7a1337f0d29..(CVE-2019-19534)In the Linux kernel before 5.2.9, there is an info-leak bug that can be caused by a malicious USB device in the drivers/ net/can/usb/peak_usb/pcan_usb_pro.c driver, aka CID-ead16e53c2f0.(CVE-2019-19536)In the Linux kernel before 5.2.10, there is a race condition bug that can be caused by a malicious USB device in the USB character device driver layer, aka CID-303911cfc5b9.\n This affects drivers/usb/core/file.c.(CVE-2019-19537)A memory leak in the cx23888_ir_probe() function in drivers/media/pci/cx23885/cx23888-ir.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering kfifo_alloc() failures, aka CID-a7b2df76b42b.(CVE-2019-19054)A memory leak in the mwifiex_pcie_alloc_cmdrsp_buf() function in drivers/ net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka CID-db8fd2cde932.(CVE-2019-19056)Two memory leaks in the mwifiex_pcie_init_evt_ring() function in drivers/ net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka CID-d10dcb615c8e.(CVE-2019-19057)A memory leak in the adis_update_scan_mode() function in drivers/iio/imu/adis_buffer.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-ab612b1daf41.(CVE-2019-19060)A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures, aka CID-ffdde5932042.(CVE-2019-19062)Two memory leaks in the rtl_usb_probe() function in drivers/ net/wireless/realtek/rtlwifi/usb.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption), aka CID-3f9361695113.(CVE-2019-19063)A memory leak in the bfad_im_get_stats() function in drivers/scsi/bfa/bfad_attr.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering bfa_port_get_stats() failures, aka CID-0e62395da2bd.(CVE-2019-19066)Memory leaks in drivers/ net/wireless/ath/ath9k/htc_hst.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering wait_for_completion_timeout() failures.

This may lead to copying up to\n 1000 kernel heap pages to the userspace. This has been\n fixed upstream in\n https://github.com/torvalds/linux/commit/a45b599ad808c3\n c982fdcdc12b0b8611c2f92824 already. The problem has\n limited scope, as users don't usually have permissions\n to access SCSI devices. On the other hand, e.g. the\n Nero user manual suggests doing `chmod o+r+w /dev/sg*`\n to make the devices accessible. NOTE: third parties\n dispute the relevance of this report, noting that the\n requirement for an attacker to have both the\n CAP_SYS_ADMIN and CAP_SYS_RAWIO capabilities makes it\n 'virtually impossible to exploit.'(CVE-2018-1000204)The\n Linux kernel through 5.3.13 has a start_offset+size\n Integer Overflow in cpia2_remap_buffer in\n drivers/media/usb/cpia2/cpia2_core.c because cpia2 has\n its own mmap implementation. This allows local users\n (with /dev/video0 access) to obtain read and write\n permissions on kernel physical pages, which can\n possibly result in a privilege\n escalation.(CVE-2019-18675)arch/x86/kvm/emulate.c in\n the Linux kernel before 4.8.12 does not properly\n initialize Code Segment (CS) in certain error cases,\n which allows local users to obtain sensitive\n information from kernel stack memory via a crafted\n application.(CVE-2016-9756)Double free vulnerability in\n drivers/ net/usb/cdc_ncm.c in the Linux kernel before\n 4.5 allows physically proximate attackers to cause a\n denial of service (system crash) or possibly have\n unspecified other impact by inserting a USB device with\n an invalid USB descriptor.(CVE-2016-3951)Linux Kernel\n contains an out-of-bounds read flaw in the\n asn1_ber_decoder() function in lib/asn1_decoder.c that\n is triggered when decoding ASN.1 data. This may allow a\n remote attacker to disclose potentially sensitive\n memory contents.(CVE-2018-9383)Linux Kernel contains a\n flaw in the ip6_setup_cork() function in\n net/ipv6/ip6_output.c that is triggered when handling\n too small IPv6 MTU sizes. This may allow a local\n attacker to cause a crash or potentially gain elevated\n privileges.(CVE-2018-9389)In the Android kernel in the\n video driver there is a use after free due to a race\n condition. This could lead to local escalation of\n privilege with no additional execution privileges\n needed. User interaction is not needed for\n exploitation.(CVE-2019-9458)An out-of-bounds memory\n write issue was found in the Linux Kernel, version 3.13\n through 5.4, in the way the Linux kernel's KVM\n hypervisor handled the 'KVM_GET_EMULATED_CPUID'\n ioctl(2) request to get CPUID features emulated by the\n KVM hypervisor. A user or process able to access the\n '/dev/kvm' device could use this flaw to crash the\n system, resulting in a denial of\n service.(CVE-2019-19332)kernel/sched/fair.c in the\n Linux kernel before 5.3.9, when cpu.cfs_quota_us is\n used (e.g., with Kubernetes), allows attackers to cause\n a denial of service against non-cpu-bound applications\n by generating a workload that triggers unwanted slice\n expiration, aka CID-de53fd7aedb1. (In other words,\n although this slice expiration would typically be seen\n with benign workloads, it is possible that an attacker\n could calculate how many stray requests are required to\n force an entire Kubernetes cluster into a\n low-performance state caused by slice expiration, and\n ensure that a DDoS attack sent that number of stray\n requests. An attack does not affect the stability of\n the kernel it only causes mismanagement of application\n execution.)(CVE-2019-19922)An exploitable\n denial-of-service vulnerability exists in the Linux\n kernel prior to mainline 5.3. An attacker could exploit\n this vulnerability by triggering AP to send IAPP\n location updates for stations before the required\n authentication process has completed. This could lead\n to different denial-of-service scenarios, either by\n causing CAM table attacks, or by leading to traffic\n flapping if faking already existing clients in other\n nearby APs of the same wireless infrastructure. An\n attacker can forge Authentication and Association\n Request packets to trigger this\n vulnerability.(CVE-2019-5108)A heap-based buffer\n overflow vulnerability was found in the Linux kernel,\n version kernel-2.6.32, in Marvell WiFi chip driver. A\n remote attacker could cause a denial of service (system\n crash) or, possibly execute arbitrary code, when the\n lbs_ibss_join_existing function is called after a STA\n connects to an AP.(CVE-2019-14896)A stack-based buffer\n overflow was found in the Linux kernel, version\n kernel-2.6.32, in Marvell WiFi chip driver. An attacker\n is able to cause a denial of service (system crash) or,\n possibly execute arbitrary code, when a STA works in\n IBSS mode (allows connecting stations together without\n the use of an AP) and connects to another\n STA.(CVE-2019-14897)In the Linux kernel through 5.4.6,\n there is a NULL pointer dereference in\n drivers/scsi/libsas/sas_discover.c because of\n mishandling of port disconnection during discovery,\n related to a PHY down race condition, aka\n CID-f70267f379b5.(CVE-2019-19965)In the Linux kernel\n before 5.1.6, there is a use-after-free in cpia2_exit()\n in drivers/media/usb/cpia2/cpia2_v4l.c that will cause\n denial of service, aka\n CID-dea37a972655.(CVE-2019-19966)In the Linux kernel\n before 5.1, there is a memory leak in\n __feat_register_sp() in net/dccp/feat.c, which may\n cause denial of service, aka\n CID-1d3ff0950e2b.(CVE-2019-20096)In the Linux kernel\n before 5.0.6, there is a NULL pointer dereference in\n drop_sysctl_table() in fs/proc/proc_sysctl.c, related\n to put_links, aka\n CID-23da9588037e.(CVE-2019-20054)drivers/\n net/usb/pegasus.c in the Linux kernel 4.9.x before\n 4.9.11 interacts incorrectly with the CONFIG_VMAP_STACK\n option, which allows local users to cause a denial of\n service (system crash or memory corruption) or possibly\n have unspecified other impact by leveraging use of more\n than one virtual page for a DMA\n scatterlist.(CVE-2017-8068)A heap-based buffer overflow\n was discovered in the Linux kernel, all versions 3.x.x\n and 4.x.x before 4.18.0, in Marvell WiFi chip driver.\n The flaw could occur when the station attempts a\n connection negotiation during the handling of the\n remote devices country settings. This could allow the\n remote device to cause a denial of service (system\n crash) or possibly execute arbitrary\n code.(CVE-2019-14895)The acpi_ds_create_operands()\n function in drivers/acpi/acpica/dsutils.c in the Linux\n kernel through 4.12.9 does not flush the operand cache\n and causes a kernel stack dump, which allows local\n users to obtain sensitive information from kernel\n memory and bypass the KASLR protection mechanism (in\n the kernel through 4.9) via a crafted ACPI\n table.(CVE-2017-13693)Linux kernel CIFS implementation,\n version 4.9.0 is vulnerable to a relative paths\n injection in directory entry lists.(CVE-2019-10220)A\n heap overflow flaw was found in the Linux kernel, all\n versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi\n chip driver. The vulnerability allows a remote attacker\n to cause a system crash, resulting in a denial of\n service, or execute arbitrary code. The highest threat\n with this vulnerability is with the availability of the\n system. If code execution occurs, the code will run\n with the permissions of root. This will affect both\n confidentiality and integrity of files on the\n system.(CVE-2019-14901)In the AppleTalk subsystem in\n the Linux kernel before 5.1, there is a potential NULL\n pointer dereference because register_snap_client may\n return NULL. This will lead to denial of service in\n net/appletalk/aarp.c and net/appletalk/ddp.c, as\n demonstrated by unregister_snap_client, aka\n CID-9804501fa122.(CVE-2019-19227)In the Linux kernel\n before 5.2.10, there is a use-after-free bug that can\n be caused by a malicious USB device in the\n drivers/usb/class/cdc-acm.c driver, aka\n CID-c52873e5a1ef.(CVE-2019-19530)In the Linux kernel\n before 5.3.9, there are multiple out-of-bounds write\n bugs that can be caused by a malicious USB device in\n the Linux kernel HID drivers, aka CID-d9d4b1e46d95.\n This affects drivers/hid/hid-axff.c,\n drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c,\n drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c,\n drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c,\n drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c,\n drivers/hid/hid-logitech-hidpp.c,\n drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c,\n drivers/hid/hid-tmff.c, and\n drivers/hid/hid-zpff.c.(CVE-2019-19532)A use-after-free\n in binder.c allows an elevation of privilege from an\n application to the Linux Kernel. No user interaction is\n required to exploit this vulnerability, however\n exploitation does require either the installation of a\n malicious local application or a separate vulnerability\n in a network facing application.Product: AndroidAndroid\n ID: A-141720095(CVE-2019-2215)The do_remount function\n in fs/ namespace.c in the Linux kernel through 3.16.1\n does not maintain the MNT_LOCK_READONLY bit across a\n remount of a bind mount, which allows local users to\n bypass an intended read-only restriction and defeat\n certain sandbox protection mechanisms via a 'mount -o\n remount' command within a user\n namespace.(CVE-2014-5206)Multiple integer overflows in\n the lzo1x_decompress_safe function in\n lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor\n in the Linux kernel before 3.15.2 allow\n context-dependent attackers to cause a denial of\n service (memory corruption) via a crafted Literal Run.\n NOTE: the author of the LZO algorithms says 'the Linux\n kernel is *not* affected media hype.'(CVE-2014-4608)The\n pivot_root implementation in fs/ namespace.c in the\n Linux kernel through 3.17 does not properly interact\n with certain locations of a chroot directory, which\n allows local users to cause a denial of service\n (mount-tree loop) via . (dot) values in both arguments\n to the pivot_root system call.(CVE-2014-7970)A security\n flaw was discovered in nl80211_set_rekey_data()\n function in the Linux kernel since v3.1-rc1 through\n v4.13. This function does not check whether the\n required attributes are present in a netlink request.\n This request can be issued by a user with CAP_NET_ADMIN\n privilege and may result in NULL

This allows local users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation.(CVE-2019-18675)\n\n - An issue was discovered in the Linux kernel through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2.(CVE-2020-9383)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c.(CVE-2020-8649)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c.(CVE-2020-8647)\n\n - The time subsystem in the Linux kernel, when CONFIG_TIMER_STATS is enabled, allows local users to discover real PID values (as distinguished from PID values inside a PID namespace) by reading the /proc/timer_list file, related to the print_timer function in kernel/time/timer_list.c and the\n __timer_stats_timer_set_start_info function in kernel/time/timer.c.(CVE-2017-5967)\n\n - ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.(CVE-2014-8181)\n\n - ext4_protect_reserved_inode in fs/ext4/block_validity.c in the Linux kernel through 5.5.3 allows attackers to cause a denial of service (soft lockup) via a crafted journal size.(CVE-2020-8992)\n\n - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER.\n ConsultIDs: CVE-2020-12826. Reason: This candidate is a duplicate of CVE-2020-12826. Notes: All CVE users should reference CVE-2020-12826 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage.(CVE-2020-10741)\n\n - A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2.\n Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial operational threat.(CVE-2020-12826)\n\n - gadget_dev_desc_UDC_store in drivers/usb/gadget/configfs.c in the Linux kernel through 5.6.13 relies on kstrdup without considering the possibility of an internal '\\0' value, which allows attackers to trigger an out-of-bounds read, aka CID-15753588bcd4.(CVE-2020-13143)\n\n - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a certain failure case, aka CID-83c6f2390040.(CVE-2020-12770)\n\n - An issue was found in Linux kernel before 5.5.4.\n mwifiex_ret_wmm_get_status() in drivers/net/wireless/marvell/mwifiex/wmm.c allows a remote AP to trigger a heap-based buffer overflow because of an incorrect memcpy, aka CID-3a9b153c5591.(CVE-2020-12654)\n\n - An issue was found in Linux kernel before 5.5.4.

issue was discovered in slc_bump in drivers/net/can/slcan.c, which allowed attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL (bnc#1168424).\n\nCVE-2020-10942: In get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls (bnc#1167629).\n\nCVE-2020-8647: Fixed a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929).\n\nCVE-2020-8649: Fixed a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162931).\n\nCVE-2020-9383: Fixed an issue in set_fdc in drivers/block/floppy.c, which leads to a wait_til_ready out-of-bounds read (bnc#1165111).\n\nCVE-2019-9458: In the video driver there was a use after free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed (bnc#1168295).\n\nCVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a system crash (bnc#1120386).\n\nCVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bnc#1159285).\n\nCVE-2020-11609: Fixed a NULL pointer dereference in the stv06xx subsystem caused by mishandling invalid descriptors (bnc#1168854).\n\nCVE-2020-10720: Fixed a use-after-free read in napi_gro_frags() (bsc#1170778).\n\nCVE-2020-10690: Fixed the race between the release of ptp_clock and cdev (bsc#1170056).\n\nCVE-2019-9455: Fixed a pointer leak due to a WARN_ON statement in a video driver. This could lead to local information disclosure with System execution privileges needed (bnc#1170345).\n\nCVE-2020-11608: Fixed an issue in drivers/media/usb/gspca/ov519.c caused by a NULL pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs when there are zero endpoints (bnc#1168829).\n\nCVE-2017-18255: The perf_cpu_time_max_percent_handler function in kernel/events/core.c allowed local users to cause a denial of service (integer overflow) or possibly have unspecified other impact via a large value, as demonstrated by an incorrect sample-rate calculation (bnc#1087813).\n\nCVE-2020-8648: There was a use-after-free vulnerability in the n_tty_receive_buf_common function in drivers/tty/n_tty.c (bnc#1162928).\n\nCVE-2020-2732: A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest (bnc#1163971).\n\nCVE-2019-5108: Fixed a denial-of-service vulnerability caused by triggering AP to send IAPP location updates for stations before the required authentication process has completed (bnc#1159912).\n\nCVE-2020-8992: ext4_protect_reserved_inode in fs/ext4/block_validity.c allowed attackers to cause a denial of service (soft lockup) via a crafted journal size (bnc#1164069).\n\nCVE-2018-21008: Fixed a use-after-free which could be caused by the function rsi_mac80211_detach in the file drivers/net/wireless/rsi/rsi_91x_mac80211.c (bnc#1149591).\n\nCVE-2019-14896: A heap-based buffer overflow vulnerability was found in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP (bnc#1157157).\n\nCVE-2019-14897: A stack-based buffer overflow was found in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA (bnc#1157155).\n\nCVE-2019-18675: Fixed an integer overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allowed local users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation (bnc#1157804).\n\nCVE-2019-14615: Insufficient control flow in certain data structures for some Intel(R) Processors with Intel(R) Processor Graphics may have allowed an unauthenticated user to potentially enable information disclosure via local access (bnc#1160195, bsc#1165881).\n\nCVE-2019-19965: Fixed a NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition (bnc#1159911).\n\nCVE-2019-20054: Fixed a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c, related to put_links (bnc#1159910).\n\nCVE-2019-20096: Fixed a memory leak in __feat_register_sp() in net/dccp/feat.c, which may cause denial of service (bnc#1159908).\n\nCVE-2019-19966: Fixed a use-after-free in cpia2_exit() in drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service (bnc#1159841).\n\nCVE-2019-19447: Fixed an issue with mounting a crafted ext4 filesystem image, performing some operations, and unmounting could lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list in fs/ext4/super.c (bnc#1158819).\n\nCVE-2019-19319: Fixed an issue with a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call (bnc#1158021).\n\nCVE-2019-19767: Fixed mishandling of ext4_expand_extra_isize, as demonstrated by use-after-free errors in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c (bnc#1159297).\n\nCVE-2019-11091,CVE-2018-12126,CVE-2018-12130,CVE-2018-12127: Earlier mitigations for the 'MDS' Microarchitectural Data Sampling attacks were not complete.

of service, or information leak.\n\nCVE-2019-2215\n\nThe syzkaller tool discovered a use-after-free vulnerability in the Android binder driver. A local user on a system with this driver enabled could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation. However, this driver is not enabled on Debian packaged kernels.\n\nCVE-2019-10220\n\nVarious developers and researchers found that if a crafted file- system or malicious file server presented a directory with filenames including a '/' character, this could confuse and possibly defeat security checks in applications that read the directory.\n\nThe kernel will now return an error when reading such a directory, rather than passing the invalid filenames on to user-space.\n\nCVE-2019-14895, CVE-2019-14901\n\nADLab of Venustech discovered potential heap buffer overflows in the mwifiex wifi driver. On systems using this driver, a malicious Wireless Access Point or adhoc/P2P peer could use these to cause a denial of service (memory corruption or crash) or possibly for remote code execution.\n\nCVE-2019-14896, CVE-2019-14897\n\nADLab of Venustech discovered potential heap and stack buffer overflows in the libertas wifi driver. On systems using this driver, a malicious Wireless Access Point or adhoc/P2P peer could use these to cause a denial of service (memory corruption or crash) or possibly for remote code execution.\n\nCVE-2019-15098\n\nHui Peng and Mathias Payer reported that the ath6kl wifi driver did not properly validate USB descriptors, which could lead to a NULL pointer derefernce. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops).\n\nCVE-2019-15217\n\nThe syzkaller tool discovered that the zr364xx mdia driver did not correctly handle devices without a product name string, which could lead to a NULL pointer dereference. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops).\n\nCVE-2019-15291\n\nThe syzkaller tool discovered that the b2c2-flexcop-usb media driver did not properly validate USB descriptors, which could lead to a NULL pointer dereference. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops).\n\nCVE-2019-15505\n\nThe syzkaller tool discovered that the technisat-usb2 media driver did not properly validate incoming IR packets, which could lead to a heap buffer over-read. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops) or to read sensitive information from kernel memory.\n\nCVE-2019-16746\n\nIt was discovered that the wifi stack did not validate the content of beacon heads provided by user-space for use on a wifi interface in Access Point mode, which could lead to a heap buffer overflow. A local user permitted to configure a wifi interface could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.\n\nCVE-2019-17052, CVE-2019-17053, CVE-2019-17054, CVE-2019-17055, CVE-2019-17056\n\nOri Nimron reported that various network protocol implementations\n\n - AX.25, IEEE 802.15.4, Appletalk, ISDN, and NFC - allowed all users to create raw sockets. A local user could use this to send arbitrary packets on networks using those protocols.\n\nCVE-2019-17133\n\nNicholas Waisman reported that the wifi stack did not valdiate received SSID information before copying it, which could lead to a buffer overflow if it is not validated by the driver or firmware. A malicious Wireless Access Point might be able to use this to cause a denial of service (memory corruption or crash) or for remote code execution.\n\nCVE-2019-17666\n\nNicholas Waisman reported that the rtlwifi wifi drivers did not properly validate received P2P information, leading to a buffer overflow. A malicious P2P peer could use this to cause a denial of service (memory corruption or crash) or for remote code execution.\n\nCVE-2019-19051\n\nNavid Emamdoost discovered a potential memory leak in the i2400m wimax driver if the software rfkill operation fails.

Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5708 advisory.\n\n - Since Linux kernel version 3.2, the mremap() syscall performs TLB flushes after dropping pagetable locks.\n If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. This is fixed in the following kernel versions:\n 4.9.135, 4.14.78, 4.18.16, 4.19. (CVE-2018-18281)\n\n - An issue was discovered in the Linux kernel before 5.6.1. drivers/media/usb/gspca/ov519.c allows NULL pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs when there are zero endpoints, aka CID-998912346c0d. (CVE-2020-11608)\n\n - An issue was discovered in the stv06xx subsystem in the Linux kernel before 5.6.1.\n drivers/media/usb/gspca/stv06xx/stv06xx.c and drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c mishandle invalid descriptors, as demonstrated by a NULL pointer dereference, aka CID-485b06aadb93. (CVE-2020-11609)\n\n - In the Linux kernel before 5.6.1, drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink camera USB driver) mishandles invalid descriptors, aka CID-a246b4d54770. (CVE-2020-11668)\n\n - The offset2lib patch as used in the Linux Kernel contains a vulnerability that allows a PIE binary to be execve()'ed with 1GB of arguments or environmental strings then the stack occupies the address 0x80000000 and the PIE binary is mapped above 0x40000000 nullifying the protection of the offset2lib patch. This affects Linux Kernel version 4.11.5 and earlier. This is a different issue than CVE-2017-1000371. This issue appears to be limited to i386 based systems. (CVE-2017-1000370)\n\n - A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA. (CVE-2019-14897)\n\n - In the Linux kernel before 5.3.12, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/input/ff-memless.c driver, aka CID-fa3a5a1880c9. (CVE-2019-19524)\n\n - In the Linux kernel before 5.3.7, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/iowarrior.c driver, aka CID-edc4746f253d.

This affects drivers/usb/core/file.c. (CVE-2019-19537)\n\n - In the Linux kernel before 5.4.12, drivers/input/input.c has out-of-bounds writes via a crafted keycode table, as demonstrated by input_set_keycode, aka CID-cb222aed03d7. (CVE-2019-20636)\n\n - An issue was discovered in the Linux kernel before 5.0. The function __mdiobus_register() in drivers/net/phy/mdio_bus.c calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free.\n This will cause a denial of service.

are affected by multiple vulnerabilities:\n\n - An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver. (CVE-2019-15217)\n\n - ieee802154_create in net/ieee802154/socket.c in the AF_IEEE802154 network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-e69dbd4619e7. (CVE-2019-17053)\n\n - base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-b91ee4aa2a21. (CVE-2019-17055)\n\n - A memory leak in the ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c in the Linux kernel through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-128c66429247.\n (CVE-2019-18808)\n\n - A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures, aka CID-ffdde5932042. (CVE-2019-19062)\n\n - An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use this flaw to crash the system, resulting in a denial of service. (CVE-2019-19332)\n\n - In the Linux kernel before 5.3.7, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/adutux.c driver, aka CID-44efc269db79. (CVE-2019-19523)\n\n - In the Linux kernel before 5.3.12, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/input/ff-memless.c driver, aka CID-fa3a5a1880c9. (CVE-2019-19524)\n\n - In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/class/cdc-acm.c driver, aka CID-c52873e5a1ef. (CVE-2019-19530)\n\n - In the Linux kernel before 5.3.11, there is an info-leak bug that can be caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver, aka CID-f7a1337f0d29. (CVE-2019-19534)\n\n - In the Linux kernel before 5.2.10, there is a race condition bug that can be caused by a malicious USB device in the USB character device driver layer, aka CID-303911cfc5b9. This affects drivers/usb/core/file.c. (CVE-2019-19537)\n\n - In the Android kernel in the video driver there is a use after free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (CVE-2019-9458)\n\n - ** DISPUTED ** An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability because the issue is a bug in parsing mount options which can only be specified by a privileged user, so triggering the bug does not grant any powers not already held.. (CVE-2020-11565)\n\n - A flaw was found in the Linux kernels implementation of the invert video code on VGA consoles when a local attacker attempts to resize the console, calling an ioctl VT_RESIZE, which causes an out-of-bounds write to occur. This flaw allows a local user with access to the VGA console to crash the system, potentially escalating their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-14331)\n\n - A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest. (CVE-2020-2732)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c.

(CVE-2019-17053)\n\n - base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through\n 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka\n CID-b91ee4aa2a21. (CVE-2019-17055)\n\n - A memory leak in the ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c in the Linux kernel\n through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-128c66429247.\n (CVE-2019-18808)\n\n - A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through\n 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering\n crypto_report_alg() failures, aka CID-ffdde5932042. (CVE-2019-19062)\n\n - An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way\n the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID\n features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use\n this flaw to crash the system, resulting in a denial of service. (CVE-2019-19332)\n\n - In the Linux kernel before 5.3.7, there is a use-after-free bug that can be caused by a malicious USB\n device in the drivers/usb/misc/adutux.c driver, aka CID-44efc269db79. (CVE-2019-19523)\n\n - In the Linux kernel before 5.3.12, there is a use-after-free bug that can be caused by a malicious USB\n device in the drivers/input/ff-memless.c driver, aka CID-fa3a5a1880c9.

This could\n lead to local escalation of privilege with no additional execution privileges needed. User interaction is\n not needed for exploitation. (CVE-2019-9458)\n\n - ** DISPUTED ** An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c\n has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing,\n aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability\n because the issue is a bug in parsing mount options which can only be specified by a privileged user, so\n triggering the bug does not grant any powers not already held.. (CVE-2020-11565)\n\n - A flaw was found in the Linux kernels implementation of the invert video code on VGA consoles when a\n local attacker attempts to resize the console, calling an ioctl VT_RESIZE, which causes an out-of-bounds\n write to occur. This flaw allows a local user with access to the VGA console to crash the system,\n potentially escalating their privileges on the system. The highest threat from this vulnerability is to\n data confidentiality and integrity as well as system availability. (CVE-2020-14331)\n\n - A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest\n when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into\n accessing sensitive L1 resources that should be inaccessible to the L2 guest. (CVE-2020-2732)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in\n drivers/tty/vt/vt.c.

An attacker within\n range of the AP could use this to cause a denial of\n service, either by filling up a switching table or by\n redirecting traffic away from other stations.\n\n - CVE-2019-19319\n Jungyeon discovered that a crafted filesystem can cause\n the ext4 implementation to deallocate or reallocate\n journal blocks. A user permitted to mount filesystems\n could use this to cause a denial of service (crash), or\n possibly for privilege escalation.\n\n - CVE-2019-19462\n The syzbot tool found a missing error check in the\n 'relay' library used to implement various files under\n debugfs. A local user permitted to access debugfs could\n use this to cause a denial of service (crash) or\n possibly for privilege escalation.\n\n - CVE-2019-19768\n Tristan Madani reported a race condition in the blktrace\n debug facility that could result in a use-after-free. A\n local user able to trigger removal of block devices\n could possibly use this to cause a denial of service\n (crash) or for privilege escalation.\n\n - CVE-2019-20806\n A potential NULL pointer dereference was discovered in\n the tw5864 media driver. The security impact of this is\n unclear.\n\n - CVE-2019-20811\n The Hulk Robot tool found a reference-counting bug in an\n error path in the network subsystem. The security impact\n of this is unclear.\n\n - CVE-2020-0543\n Researchers at VU Amsterdam discovered that on some\n Intel CPUs supporting the RDRAND and RDSEED\n instructions, part of a random value generated by these\n instructions may be used in a later speculative\n execution on any core of the same physical CPU.\n Depending on how these instructions are used by\n applications, a local user or VM guest could use this to\n obtain sensitive information such as cryptographic keys\n from other users or VMs.\n\n This vulnerability can be mitigated by a microcode update, either as\n part of system firmware (BIOS) or through the intel-microcode\n package in Debian's non-free archive section. This kernel update\n only provides reporting of the vulnerability and the option to\n disable the mitigation if it is not needed.\n\n - CVE-2020-2732\n Paulo Bonzini discovered that the KVM implementation for\n Intel processors did not properly handle instruction\n emulation for L2 guests when nested virtualization is\n enabled. This could allow an L2 guest to cause privilege\n escalation, denial of service, or information leaks in\n the L1 guest.\n\n - CVE-2020-8428\n Al Viro discovered a potential use-after-free in the\n filesystem core (vfs). A local user could exploit this\n to cause a denial of service (crash) or possibly to\n obtain sensitive information from the kernel.\n\n - CVE-2020-8647, CVE-2020-8649\n The Hulk Robot tool found a potential MMIO out-of-bounds\n access in the vgacon driver. A local user permitted to\n access a virtual terminal (/dev/tty1 etc.) on a system\n using the vgacon driver could use this to cause a denial\n of service (crash or memory corruption) or possibly for\n privilege escalation.\n\n - CVE-2020-8648\n The syzbot tool found a race condition in the the\n virtual terminal driver, which could result in a\n use-after-free. A local user permitted to access a\n virtual terminal could use this to cause a denial of\n service (crash or memory corruption) or possibly for\n privilege escalation.\n\n - CVE-2020-9383\n Jordy Zomer reported an incorrect range check in the\n floppy driver which could lead to a static out-of-bounds\n access. A local user permitted to access a floppy drive\n could use this to cause a denial of service (crash or\n memory corruption) or possibly for privilege escalation.\n\n - CVE-2020-10711\n Matthew Sheets reported NULL pointer dereference issues\n in the SELinux subsystem while receiving CIPSO packet\n with null category. A remote attacker can take advantage\n of this flaw to cause a denial of service (crash). Note\n that this issue does not affect the binary packages\n distributed in Debian as CONFIG_NETLABEL is not enabled.\n\n - CVE-2020-10732\n An information leak of kernel private memory to\n userspace was found in the kernel's implementation of\n core dumping userspace processes.\n\n - CVE-2020-10751\n Dmitry Vyukov reported that the SELinux subsystem did\n not properly handle validating multiple messages, which\n could allow a privileged attacker to bypass SELinux\n netlink restrictions.\n\n - CVE-2020-10757\n Fan Yang reported a flaw in the way mremap handled DAX\n hugepages, allowing a local user to escalate their\n privileges\n\n - CVE-2020-10942\n It was discovered that the vhost_net driver did not\n properly validate the type of sockets set as back-ends.\n A local user permitted to access /dev/vhost-net could\n use this to cause a stack corruption via crafted system\n calls, resulting in denial of service (crash) or\n possibly privilege escalation.\n\n - CVE-2020-11494\n It was discovered that the slcan (serial line CAN)\n network driver did not fully initialise CAN headers for\n received packets, resulting in an information leak from\n the kernel to user-space or over the CAN network.\n\n - CVE-2020-11565\n Entropy Moe reported that the shared memory filesystem\n (tmpfs) did not correctly handle an 'mpol' mount option\n specifying an empty node list, leading to a stack-based\n out-of-bounds write. If user namespaces are enabled, a\n local user could use this to cause a denial of service\n (crash) or possibly for privilege escalation.\n\n - CVE-2020-11608, CVE-2020-11609, CVE-2020-11668\n It was discovered that the ov519, stv06xx, and\n xirlink_cit media drivers did not properly validate USB\n device descriptors. A physically present user with a\n specially constructed USB device could use this to cause\n a denial-of-service (crash) or possibly for privilege\n escalation.\n\n - CVE-2020-12114\n Piotr Krysiuk discovered a race condition between the\n umount and pivot_root operations in the filesystem core\n (vfs).

It is not clear how\n this can be exploited, but it could result in a denial\n of service (crash or memory corruption) or privilege\n escalation.\n\n - CVE-2020-12652\n Tom Hatskevich reported a bug in the mptfusion storage\n drivers. An ioctl handler fetched a parameter from user\n memory twice, creating a race condition which could\n result in incorrect locking of internal data structures.\n A local user permitted to access /dev/mptctl could use\n this to cause a denial of service (crash or memory\n corruption) or for privilege escalation.\n\n - CVE-2020-12653\n It was discovered that the mwifiex WiFi driver did not\n sufficiently validate scan requests, resulting a\n potential heap buffer overflow. A local user with\n CAP_NET_ADMIN capability could use this to cause a\n denial of service (crash or memory corruption) or\n possibly for privilege escalation.\n\n - CVE-2020-12654\n It was discovered that the mwifiex WiFi driver did not\n sufficiently validate WMM parameters received from an\n access point (AP), resulting a potential heap buffer\n overflow. A malicious AP could use this to cause a\n denial of service (crash or memory corruption) or\n possibly to execute code on a vulnerable system.\n\n - CVE-2020-12770\n It was discovered that the sg (SCSI generic) driver did\n not correctly release internal resources in a particular\n error case. A local user permitted to access an sg\n device could possibly use this to cause a denial of\n service (resource exhaustion).\n\n - CVE-2020-13143\n Kyungtae Kim reported a potential heap out-of-bounds\n write in the USB gadget subsystem. A local user\n permitted to write to the gadget configuration\n filesystem could use this to cause a denial of service\n (crash or memory corruption) or potentially for\n privilege escalation.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=952660\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2019-2182\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2019-5108\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2019-19319\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2019-19462\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2019-19768\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2019-20806\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2019-20811\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-0543\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-2732\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-8428\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-8647\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-8649\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-8648\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-9383\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-10711\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-10732\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-10751\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-10757\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-10942\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-11494\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-11565\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-11608\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-11609\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-11668\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-12114\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-12464\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-12652\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-12653\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-12654\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-12770\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2020-13143\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/source-package/linux\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://packages.debian.org/source/stretch/linux\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://www.debian.org/security/2020/dsa-4698\"\n );\n script_set_attribute(\n attribute:\"solution\",\n value:\n\"Upgrade the linux packages.\n\nFor the oldstable distribution (stretch), these problems have been\nfixed in version 4.9.210-1+deb9u1.

privilege escalation, denial of service or information leaks.\n\nCVE-2019-2182\n\nHanjun Guo and Lei Li reported a race condition in the arm64 virtual memory management code, which could lead to an information disclosure, denial of service (crash), or possibly privilege escalation.\n\nCVE-2019-5108\n\nMitchell Frank of Cisco discovered that when the IEEE 802.11 (WiFi) stack was used in AP mode with roaming, it would trigger roaming for a newly associated station before the station was authenticated. An attacker within range of the AP could use this to cause a denial of service, either by filling up a switching table or by redirecting traffic away from other stations.\n\nCVE-2019-19319\n\nJungyeon discovered that a crafted filesystem can cause the ext4 implementation to deallocate or reallocate journal blocks. A user permitted to mount filesystems could use this to cause a denial of service (crash), or possibly for privilege escalation.\n\nCVE-2019-19462\n\nThe syzbot tool found a missing error check in the 'relay' library used to implement various files under debugfs. A local user permitted to access debugfs could use this to cause a denial of service (crash) or possibly for privilege escalation.\n\nCVE-2019-19768\n\nTristan Madani reported a race condition in the blktrace debug facility that could result in a use-after-free. A local user able to trigger removal of block devices could possibly use this to cause a denial of service (crash) or for privilege escalation.\n\nCVE-2019-20806\n\nA potential NULL pointer dereference was discovered in the tw5864 media driver. The security impact of this is unclear.\n\nCVE-2019-20811\n\nThe Hulk Robot tool found a reference-counting bug in an error path in the network subsystem. The security impact of this is unclear.\n\nCVE-2020-0543\n\nResearchers at VU Amsterdam discovered that on some Intel CPUs supporting the RDRAND and RDSEED instructions, part of a random value generated by these instructions may be used in a later speculative execution on any core of the same physical CPU. Depending on how these instructions are used by applications, a local user or VM guest could use this to obtain sensitive information such as cryptographic keys from other users or VMs.\n\nThis vulnerability can be mitigated by a microcode update, either as part of system firmware (BIOS) or through the intel-microcode package in Debian's non-free archive section. This kernel update only provides reporting of the vulnerability and the option to disable the mitigation if it is not needed.\n\nCVE-2020-2732\n\nPaulo Bonzini discovered that the KVM implementation for Intel processors did not properly handle instruction emulation for L2 guests when nested virtualization is enabled. This could allow an L2 guest to cause privilege escalation, denial of service, or information leaks in the L1 guest.\n\nCVE-2020-8428\n\nAl Viro discovered a potential use-after-free in the filesystem core (vfs). A local user could exploit this to cause a denial of service (crash) or possibly to obtain sensitive information from the kernel.\n\nCVE-2020-8647, CVE-2020-8649\n\nThe Hulk Robot tool found a potential MMIO out-of-bounds access in the vgacon driver. A local user permitted to access a virtual terminal (/dev/tty1 etc.) on a system using the vgacon driver could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-8648\n\nThe syzbot tool found a race condition in the the virtual terminal driver, which could result in a use-after-free. A local user permitted to access a virtual terminal could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-9383\n\nJordy Zomer reported an incorrect range check in the floppy driver which could lead to a static out-of-bounds access. A local user permitted to access a floppy drive could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-10711\n\nMatthew Sheets reported NULL pointer dereference issues in the SELinux subsystem while receiving CIPSO packet with null category. A remote attacker can take advantage of this flaw to cause a denial of service (crash). Note that this issue does not affect the binary packages distributed in Debian as CONFIG_NETLABEL is not enabled.\n\nCVE-2020-10732\n\nAn information leak of kernel private memory to userspace was found in the kernel's implementation of core dumping userspace processes.\n\nCVE-2020-10751\n\nDmitry Vyukov reported that the SELinux subsystem did not properly handle validating multiple messages, which could allow a privileged attacker to bypass SELinux netlink restrictions.\n\nCVE-2020-10757\n\nFan Yang reported a flaw in the way mremap handled DAX hugepages, allowing a local user to escalate their privileges\n\nCVE-2020-10942\n\nIt was discovered that the vhost_net driver did not properly validate the type of sockets set as back-ends. A local user permitted to access /dev/vhost-net could use this to cause a stack corruption via crafted system calls, resulting in denial of service (crash) or possibly privilege escalation.\n\nCVE-2020-11494\n\nIt was discovered that the slcan (serial line CAN) network driver did not fully initialise CAN headers for received packets, resulting in an information leak from the kernel to user-space or over the CAN network.\n\nCVE-2020-11565\n\nEntropy Moe reported that the shared memory filesystem (tmpfs) did not correctly handle an 'mpol' mount option specifying an empty node list, leading to a stack-based out-of-bounds write. If user namespaces are enabled, a local user could use this to cause a denial of service (crash) or possibly for privilege escalation.\n\nCVE-2020-11608, CVE-2020-11609, CVE-2020-11668\n\nIt was discovered that the ov519, stv06xx, and xirlink_cit media drivers did not properly validate USB device descriptors. A physically present user with a specially constructed USB device could use this to cause a denial of service (crash) or possibly for privilege escalation.\n\nCVE-2020-12114\n\nPiotr Krysiuk discovered a race condition between the umount and pivot_root operations in the filesystem core (vfs). A local user with the CAP_SYS_ADMIN capability in any user namespace could use this to cause a denial of service (crash).\n\nCVE-2020-12464\n\nKyungtae Kim reported a race condition in the USB core that can result in a use-after-free. It is not clear how this can be exploited, but it could result in a denial of service (crash or memory corruption) or privilege escalation.\n\nCVE-2020-12652\n\nTom Hatskevich reported a bug in the mptfusion storage drivers. An ioctl handler fetched a parameter from user memory twice, creating a race condition which could result in incorrect locking of internal data structures. A local user permitted to access /dev/mptctl could use this to cause a denial of service (crash or memory corruption) or for privilege escalation.\n\nCVE-2020-12653\n\nIt was discovered that the mwifiex WiFi driver did not sufficiently validate scan requests, resulting a potential heap buffer overflow. A local user with CAP_NET_ADMIN capability could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-12654\n\nIt was discovered that the mwifiex WiFi driver did not sufficiently validate WMM parameters received from an access point (AP), resulting a potential heap buffer overflow. A malicious AP could use this to cause a denial of service (crash or memory corruption) or possibly to execute code on a vulnerable system.\n\nCVE-2020-12770\n\nIt was discovered that the sg (SCSI generic) driver did not correctly release internal resources in a particular error case. A local user permitted to access an sg device could possibly use this to cause a denial of service (resource exhaustion).\n\nCVE-2020-13143\n\nKyungtae Kim reported a potential heap out-of-bounds write in the USB gadget subsystem. A local user permitted to write to the gadget configuration filesystem could use this to cause a denial of service (crash or memory corruption) or potentially for privilege escalation.\n\nFor Debian 8 'Jessie', these problems have been fixed in version 4.9.210-1+deb9u1~deb8u1. This version also fixes some related bugs that do not have their own CVE IDs, and a regression in the macvlan driver introduced in the previous security update (bug #952660).\n\nWe recommend that you upgrade your linux-4.9 packages.\n\nNOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory.

"According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :\n\n - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system:\n memory allocation, process allocation, device input and output, etc.Security Fix(es):Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory entry lists.(CVE-2019-10220)A memory leak in the i2400m_op_rfkill_sw_toggle() function in drivers/ net/wimax/i2400m/op-rfkill.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-6f3ef5c25cc7.(CVE-2019-19051)A memory leak in the sdma_init() function in drivers/infiniband/hw/hfi1/sdma.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering rhashtable_init() failures, aka CID-34b3be18a04e.(CVE-2019-19065)Four memory leaks in the acp_hw_init() function in drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c in the Linux kernel before 5.3.8 allow attackers to cause a denial of service (memory consumption) by triggering mfd_add_hotplug_devices() or pm_genpd_add_device() failures, aka CID-57be09c6e874. NOTE: third parties dispute the relevance of this because the attacker must already have privileges for module loading.(CVE-2019-19067)An issue was discovered in drivers/xen/balloon.c in the Linux kernel before 5.2.3, as used in Xen through 4.12.x, allowing guest OS users to cause a denial of service because of unrestricted resource consumption during the mapping of guest memory, aka CID-6ef36ab967c7.(CVE-2019-17351)The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation.(CVE-2017-12134)In the Linux kernel before 5.3.7, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/adutux.c driver, aka CID-44efc269db79.(CVE-2019-19523)In the Linux kernel before 5.3.7, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/iowarrior.c driver, aka CID-edc4746f253d.(CVE-2019-19528)In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/class/cdc-acm.c driver, aka CID-c52873e5a1ef.(CVE-2019-19530)In the Linux kernel before 5.3.4, there is an info-leak bug that can be caused by a malicious USB device in the drivers/media/usb/ttusb-dec/ttusb_dec.c driver, aka CID-a10feaf8c464.(CVE-2019-19533)In the Linux kernel before 5.2.10, there is a race condition bug that can be caused by a malicious USB device in the USB character device driver layer, aka CID-303911cfc5b9.\n This affects drivers/usb/core/file.c.(CVE-2019-19537)In the Linux kernel before 5.3.12, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/input/ff-memless.c driver, aka CID-fa3a5a1880c9.(CVE-2019-19524)In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/hid/usbhid/hiddev.c driver, aka CID-9c09b214f30e.(CVE-2019-19527)In the Linux kernel before 5.3.9, there are multiple out-of-bounds write bugs that can be caused by a malicious USB device in the Linux kernel HID drivers, aka CID-d9d4b1e46d95.\n This affects drivers/hid/hid-axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c, drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c, drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c, drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c, drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid-tmff.c, and drivers/hid/hid-zpff.c.(CVE-2019-19532)The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allows local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program.(CVE-2015-1350)In the Linux kernel before 5.2.9, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/yurex.c driver, aka CID-fc05481b2fca.(CVE-2019-19531)The Linux kernel through 5.3.13 has a start_offset+size Integer Overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allows local users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation.(CVE-2019-18675)A flaw was found in the way signature calculation was handled by cephx authentication protocol.

The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code.(CVE-2019-14895)\n\n - A flaw was found in the fix for CVE-2019-11135, the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort (TAA) error occurs. When a guest is running on a host CPU affected by the TAA flaw (TAA_NO=0), but is not affected by the MDS issue (MDS_NO=1), the guest was to clear the affected buffers by using a VERW instruction mechanism. But when the MDS_NO=1 bit was exported to the guests, the guests did not use the VERW mechanism to clear the affected buffers. This issue affects guests running on Cascade Lake CPUs and requires that host has 'TSX' enabled.\n Confidentiality of data is the highest threat associated with this vulnerability.(CVE-2019-19338)\n\n - A flaw was found in the way Intel CPUs handle speculative execution of instructions when the TSX Asynchronous Abort (TAA) error occurs. A local authenticated attacker with the ability to monitor execution times could infer the TSX memory state by comparing abort execution times. This could allow information disclosure via this observed side-channel for any TSX transaction being executed while an attacker is able to observe abort timing. Intel's Transactional Synchronisation Extensions (TSX) are set of instructions which enable transactional memory support to improve performance of the multi-threaded applications, in the lock-protected critical sections.\n The CPU executes instructions in the critical-sections as transactions, while ensuring their atomic state.\n When such transaction execution is unsuccessful, the processor cannot ensure atomic updates to the transaction memory, so the processor rolls back or aborts such transaction execution. While TSX Asynchronous Abort (TAA) is pending, CPU may continue to read data from architectural buffers and pass it to the dependent speculative operations. This may cause information leakage via speculative side-channel means, which is quite similar to the Microarchitectural Data Sampling (MDS) issue.(CVE-2019-11135)\n\n - An out-of-bounds memory write issue was found in the way the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use this flaw to crash the system, resulting in a denial of service.(CVE-2019-19332)\n\n - A flaw was found in the Linux kernel's scheduler, where it can allow attackers to cause a denial of service against non-CPU-bound applications by generating a workload that triggers unwanted scheduling slice expiration. A local attacker who can trigger a specific workload type could abuse this technique to trigger a system to be seen as degraded, and possibly trigger workload-rebalance in systems that use the slice-expiration metric as a measure of system health.(CVE-2019-19922)\n\n - A stack-based buffer overflow was found in the Linux kernel's Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA.(CVE-2019-14897)\n\n - A heap-based buffer overflow vulnerability was found in the Linux kernel's Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.(CVE-2019-14896)\n\n - A flaw was found in the Linux kernel in versions through 5.4.6, containing information leaks of uninitialized memory to a USB device. The latest findings show that the uninitialized memory allocation was not leading to an information leak, but was allocating the memory assigned with data on the next line and hence causing no violation..(CVE-2019-19947)\n\n - A flaw was found in the Linux kernel's implementation of the Datagram Congestion Control Protocol (DCCP). A local attacker with access to the system can create DCCP sockets to cause a memory leak and repeat this operation to exhaust all memory and panic the system.(CVE-2019-20096)\n\n - A flaw was found in the Linux kernel's mwifiex driver implementation when connecting to other WiFi devices in 'Test Mode.' A kernel memory leak can occur if an error condition is met during the parameter negotiation. This issue can lead to a denial of service if multiple error conditions meeting the repeated connection attempts are attempted.(CVE-2019-20095)\n\n - A flaw was found in the Linux kernel's implementation of the WiFi station handoff code. An attacker within the radio range could use this flaw to deny a valid device from joining the access point.(CVE-2019-5108)\n\n - A flaw was found in the way Linux kernel's KVM hypervisor handled deferred TLB flush requests from guest. A race condition may occur between the guest issuing a deferred TLB flush request to KVM, and then KVM handling and acknowledging it. This may result in invalid address translations from TLB being used to access guest memory, leading to a potential information leakage issue. An attacker may use this flaw to access guest memory locations that it should not have access to.(CVE-2019-3016)\n\n - fs/namei.c in the Linux kernel before 5.5 has a may_create_in_sticky use-after-free, which allows local users to cause a denial of service (OOPS) or possibly obtain sensitive information from kernel memory, aka CID-d0cb50185ae9. One attack vector may be an open system call for a UNIX domain socket, if the socket is being moved to a new parent directory and its old parent directory is being removed.(CVE-2020-8428)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the n_tty_receive_buf_common function in drivers/tty/n_tty.c.(CVE-2020-8648)\n\n - An issue was discovered in the Linux kernel through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2.(CVE-2020-9383)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c.(CVE-2020-8649)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c.(CVE-2020-8647)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

was updated to receive various security and bugfixes.\n\nThe following security bugs were fixed :\n\nCVE-2019-14895: A heap-based buffer overflow was discovered in the Linux kernel in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could have allowed the remote device to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1157158).\n\nCVE-2019-18660: The Linux kernel on powerpc allowed Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c (bnc#1157038).\n\nCVE-2019-18683: An issue was discovered in drivers/media/platform/vivid in the Linux kernel. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded.\nThere are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free (bnc#1155897).\n\nCVE-2019-19062: A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures (bnc#1157333).\n\nCVE-2019-19065: A memory leak in the sdma_init() function in drivers/infiniband/hw/hfi1/sdma.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering rhashtable_init() failures (bnc#1157191).\n\nCVE-2019-19052: A memory leak in the gs_can_open() function in drivers/net/can/usb/gs_usb.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures (bnc#1157324).\n\nCVE-2019-19074: A memory leak in the ath9k_wmi_cmd() function in drivers/net/wireless/ath/ath9k/wmi.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) (bnc#1157143).\n\nCVE-2019-19073: Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering wait_for_completion_timeout() failures. This affects the htc_config_pipe_credits() function, the htc_setup_complete() function, and the htc_connect_service() function (bnc#1157070).\n\nCVE-2019-16231: drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 did not check the alloc_workqueue return value, leading to a NULL pointer dereference (bnc#1150466).\n\nCVE-2019-18805: An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel There was a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact (bnc#1156187).\n\nCVE-2019-18680: An issue was discovered in the Linux kernel. There was a NULL pointer dereference in rds_tcp_kill_sock() in net/rds/tcp.c that will cause denial of service (bnc#1155898).\n\nCVE-2019-15213: An use-after-free was fixed caused by malicious USB device in drivers/media/usb/dvb-usb/dvb-usb-init.c (bsc#1146544).\n\nCVE-2019-19536: An uninitialized Kernel memory can leak to USB devices in drivers/net/can/usb/peak_usb/pcan_usb_pro.c (bsc#1158394).\n\nCVE-2019-19534: An uninitialized Kernel memory can leak to USB devices in drivers/net/can/usb/peak_usb/pcan_usb_core.c (bsc#1158398).\n\nCVE-2019-19530: An use-after-free bug that can be caused by a malicious USB device in the drivers/usb/class/cdc-acm.c driver (bsc#1158410).\n\nCVE-2019-19524: An use-after-free bug that can be caused by a malicious USB device in the drivers/input/ff-memless.c driver (bsc#1158413).\n\nCVE-2019-19525: An use-after-free bug that can be caused by a malicious USB device in the drivers/net/ieee802154/atusb.c driver (bsc#1158417).\n\nCVE-2019-19531: An use-after-free in yurex_delete may lead to denial of service (bsc#1158445).\n\nCVE-2019-19523: An use-after-free on disconnect in USB adutux (bsc#1158823).\n\nCVE-2019-19532: An out-of-bounds write bugs that can be caused by a malicious USB device in the Linux kernel HID drivers (bsc#1158824).\n\nCVE-2019-19332: An out-of-bounds memory write via kvm_dev_ioctl_get_cpuid (bsc#1158827).\n\nCVE-2019-19533: An info-leak bug that can be caused by a malicious USB device in the drivers/media/usb/ttusb-dec/ttusb_dec.c driver (bsc#1158834).\n\nCVE-2019-19527: An use-after-free bug that can be caused by a malicious USB device in the drivers/hid/usbhid/hiddev.c driver (bsc#1158900).\n\nCVE-2019-19535: An info-leak bug that can be caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_fd.c driver (bsc#1158903).\n\nCVE-2019-19537: Two races in the USB character device registration and deregistration routines (bsc#1158904).\n\nCVE-2019-19338: An incomplete fix for Transaction Asynchronous Abort (TAA) (bsc#1158954).\n\nThe update package also includes non-security fixes.
