vulnerabilities as referenced in the ELSA-2020-5715 advisory.\n\n - The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c. (CVE-2019-11599)\n\n - The Broadcom brcmfmac WiFi driver prior to commit 1b5e2423164b3670e8bc9174e4762d297990deff is vulnerable to a heap buffer overflow. If the Wake-up on Wireless LAN functionality is configured, a malicious event frame can be constructed to trigger an heap buffer overflow in the brcmf_wowl_nd_results function. This vulnerability can be exploited with compromised chipsets to compromise the host, or when used in combination with CVE-2019-9503, can be used remotely. In the worst case scenario, by sending specially- crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. More typically, this vulnerability will result in denial-of-service conditions.\n (CVE-2019-9500)\n\n - The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source, the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver receives the firmware event frame from the host, the appropriate handler is called. This frame validation can be bypassed if the bus used is USB (for instance by a wifi dongle). This can allow firmware event frames from a remote source to be processed. In the worst case scenario, by sending specially-crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.\n More typically, this vulnerability will result in denial-of-service conditions. (CVE-2019-9503)\n\n - 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)\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 - 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 5.2.10, 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 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. (CVE-2019-12819)\n\n - 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)\n\n - 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.\n (CVE-2019-14896)\n\n - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via crafted USB device traffic (which may be remote via usbip or usbredir). (CVE-2019-15505)\n\n - The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code. (CVE-2019-18282)\n\n - The Linux kernel before 5.4.2 mishandles 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, aka CID-4ea99936a163. (CVE-2019-19767)\n\n - Incomplete cleanup from specific special register read operations in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-0543)\n\n - ** DISPUTED ** An issue was discovered in the Linux kernel before 5.6. svm_cpu_uninit in arch/x86/kvm/svm.c has a memory leak, aka CID-d80b64ff297e. NOTE: third parties dispute this issue because it's a one-time leak at the boot, the size is negligible, and it can't be triggered at will.\n (CVE-2020-12768)\n\n - A memory leak in the mlx5_fpga_conn_create_cq() function in drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering mlx5_vector2eqn() failures, aka CID-c8c2a057fdc7. (CVE-2019-19045)\n\n - A memory leak in the alloc_sgtable() function in drivers/net/wireless/intel/iwlwifi/fw/dbg.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering alloc_page() failures, aka CID-b4b814fec1a5.

(CVE-2019-12819)\n\n - Two memory leaks in the mwifiex_pcie_init_evt_ring() function in\n drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allow attackers to cause a\n denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka\n CID-d10dcb615c8e. (CVE-2019-19057)\n\n - A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in\n Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly\n execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.\n (CVE-2019-14896)\n\n - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via\n crafted USB device traffic (which may be remote via usbip or usbredir). (CVE-2019-15505)\n\n - The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking\n vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on\n a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value\n remains the same starting from boot time, and can be inferred by an attacker. This affects\n net/core/flow_dissector.c and related code. (CVE-2019-18282)\n\n - The Linux kernel before 5.4.2 mishandles ext4_expand_extra_isize, as demonstrated by use-after-free errors\n in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c, aka\n CID-4ea99936a163. (CVE-2019-19767)\n\n - Incomplete cleanup from specific special register read operations in some Intel(R) Processors may allow an\n authenticated user to potentially enable information disclosure via local access. (CVE-2020-0543)\n\n - ** DISPUTED ** An issue was discovered in the Linux kernel before 5.6. svm_cpu_uninit in\n arch/x86/kvm/svm.c has a memory leak, aka CID-d80b64ff297e. NOTE: third parties dispute this issue because\n it's a one-time leak at the boot, the size is negligible, and it can't be triggered at will.\n (CVE-2020-12768)\n\n - A memory leak in the mlx5_fpga_conn_create_cq() function in\n drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c in the Linux kernel before 5.3.11 allows attackers to\n cause a denial of service (memory consumption) by triggering mlx5_vector2eqn() failures, aka\n CID-c8c2a057fdc7. (CVE-2019-19045)\n\n - A memory leak in the alloc_sgtable() function in drivers/net/wireless/intel/iwlwifi/fw/dbg.c in the Linux\n kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering\n alloc_page() failures, aka CID-b4b814fec1a5. (CVE-2019-19058)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\",

"2023-02-05T14:38:57", "description": "The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2019:14218-1 advisory.\n\n - An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific socket option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before 4.9.187. (CVE-2017-18509)\n\n - An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an out of bounds write in the function i2c_smbus_xfer_emulated. (CVE-2017-18551)\n\n - Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access. (CVE-2018-12207)\n\n - An issue was discovered in fs/xfs/xfs_super.c in the Linux kernel before 4.18. A use after free exists, related to xfs_fs_fill_super failure. (CVE-2018-20976)\n\n - Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory entry lists. (CVE-2019-10220)\n\n - TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2019-11135)\n\n - An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system. (CVE-2019-14821)\n\n - A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host. (CVE-2019-14835)\n\n - check_input_term in sound/usb/mixer.c in the Linux kernel through 5.2.9 mishandles recursion, leading to kernel stack exhaustion. (CVE-2019-15118)\n\n - An issue was discovered in the Linux kernel before 5.1.8. There is a double-free caused by a malicious USB device in the drivers/usb/misc/rio500.c driver. (CVE-2019-15212)\n\n - An issue was discovered in the Linux kernel before 5.0.14. There is a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/yurex.c driver. (CVE-2019-15216)\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 - An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a malicious USB device in the drivers/usb/misc/sisusbvga/sisusb.c driver. (CVE-2019-15219)\n\n - An issue was discovered in the Linux kernel through 5.2.9. There is a NULL pointer dereference caused by a malicious USB device in the flexcop_usb_probe function in the drivers/media/usb/b2c2/flexcop-usb.c driver.\n (CVE-2019-15291)\n\n - An issue was discovered in the Linux kernel before 5.0.9. There is a use-after-free in atalk_proc_exit, related to net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and net/appletalk/sysctl_net_atalk.c.\n (CVE-2019-15292)\n\n - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via crafted USB device traffic (which may be remote via usbip or usbredir). (CVE-2019-15505)\n\n - In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS expander discovery fails. This will cause a BUG and denial of service. (CVE-2019-15807)\n\n - A backporting error was discovered in the Linux stable/longterm kernel 4.4.x through 4.4.190, 4.9.x through 4.9.190, 4.14.x through 4.14.141, 4.19.x through 4.19.69, and 5.2.x through 5.2.11. Misuse of the upstream x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg() commit reintroduced the Spectre vulnerability that it aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped. (CVE-2019-15902)\n\n - An issue was discovered in the Linux kernel before 4.20.2. An out-of-bounds access exists in the function build_audio_procunit in the file sound/usb/mixer.c. (CVE-2019-15927)\n\n - drivers/net/wireless/marvell/libertas/if_sdio.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16232)\n\n - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16233)\n\n - drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16234)\n\n - An issue was discovered in the Linux kernel before 5.0.4. The 9p filesystem did not protect i_size_write() properly, which causes an i_size_read() infinite loop and denial of service on SMP systems.\n (CVE-2019-16413)\n\n - ax25_create in net/ax25/af_ax25.c in the AF_AX25 network module in the Linux kernel 3.16 through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-0614e2b73768. (CVE-2019-17052)\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 - atalk_create in net/appletalk/ddp.c in the AF_APPLETALK 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-6cc03e8aa36c. (CVE-2019-17054)\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 - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)\n\n - In the Android kernel in Pixel C USB monitor driver there is a possible OOB write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.

(CVE-2019-6974)\n\n - The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free. (CVE-2019-7221)\n\n - The KVM implementation in the Linux kernel through 4.20.5 has an Information Leak. (CVE-2019-7222)\n\n - A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after- free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. (CVE-2018-16884)\n\n - A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network. (CVE-2019-3846)\n\n - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after- free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests. (CVE-2019-11487)\n\n - An issue was discovered in the Linux kernel before 4.18.7. In block/blk-core.c, there is an\n __blk_drain_queue() use-after-free because a certain error case is mishandled. (CVE-2018-20856)\n\n - The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are believed to be vulnerable. (CVE-2019-3874)\n\n - The fix for CVE-2019-11599, affecting the Linux kernel before 5.0.10 was not complete. A local user could use this flaw to obtain sensitive information, cause a denial of service, or possibly have other unspecified impacts by triggering a race condition with mmget_not_zero or get_task_mm calls.\n (CVE-2019-14898)\n\n - 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)\n\n - An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check the length of variable elements in a beacon head, leading to a buffer overflow. (CVE-2019-16746)\n\n - 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)\n\n - 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)\n\n - In the Linux kernel before 5.1, there is a memory leak in __feat_register_sp() in net/dccp/feat.c, which may cause denial of service, aka CID-1d3ff0950e2b. (CVE-2019-20096)\n\n - A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality. (CVE-2020-1749)\n\n - 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 affects the htc_config_pipe_credits() function, the htc_setup_complete() function, and the htc_connect_service() function, aka CID-853acf7caf10. (CVE-2019-19073)\n\n - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via crafted USB device traffic (which may be remote via usbip or usbredir).

The prb_calc_retire_blk_tmo() function in net/packet/af_packet.c can result in a denial of service (CPU consumption and soft lockup) in a certain failure case involving TPACKET_V3, aka CID-b43d1f9f7067. (CVE-2019-20812)\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 - fs/btrfs/volumes.c in the Linux kernel before 5.1 allows a btrfs_verify_dev_extents NULL pointer dereference via a crafted btrfs image because fs_devices->devices is mishandled within find_device, aka CID-09ba3bc9dd15. (CVE-2019-18885)\n\n - A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4 bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat, leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of service. (CVE-2020-10769)\n\n - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly only validate the first netlink message in the skb and allow or deny the rest of the messages within the skb with the granted permission without further processing. (CVE-2020-10751)\n\n - 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)\n\n - An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable.\n This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an architecture for which this stack/DMA interaction has security relevance. (CVE-2019-17075)\n\n - An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/siano/smsusb.c driver. (CVE-2019-15218)\n\n - A memory leak in the gs_can_open() function in drivers/net/can/usb/gs_usb.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka CID-fb5be6a7b486. (CVE-2019-19052)\n\n - An issue was discovered in fs/gfs2/rgrp.c in the Linux kernel before 4.8. A use-after-free is caused by the functions gfs2_clear_rgrpd and read_rindex_entry. (CVE-2016-10905)\n\n - An issue was discovered in drivers/net/ethernet/arc/emac_main.c in the Linux kernel before 4.5. A use- after-free is caused by a race condition between the functions arc_emac_tx and arc_emac_tx_clean.\n (CVE-2016-10906)\n\n - The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel before 4.10.4 allows local users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling.\n (CVE-2017-8925)\n\n - A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash the system if the directory exists. The highest threat from this vulnerability is to system availability.\n (CVE-2020-14314)\n\n - sound/core/seq_device.c in the Linux kernel before 4.13.4 allows local users to cause a denial of service (snd_rawmidi_dev_seq_free use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device. (CVE-2017-16528)\n\n - The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel before 4.10.4 allows local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer underflow. (CVE-2017-8924)\n\n - In driver_override_store and driver_override_show of bus.c, there is a possible double free due to improper locking. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android ID: A-69129004 References: Upstream kernel. (CVE-2018-9415)\n\n - An issue was discovered in the Linux kernel before 4.20.2. An out-of-bounds access exists in the function build_audio_procunit in the file sound/usb/mixer.c. (CVE-2019-15927)\n\n - A flaw was found in the Linux kernel's implementation of GRO in versions before 5.2. This flaw allows an attacker with local access to crash the system. (CVE-2020-10720)\n\n - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. (CVE-2020-25212)\n\n - The rbd block device driver in drivers/block/rbd.c in the Linux kernel through 5.8.9 used incomplete permission checking for access to rbd devices, which could be leveraged by local attackers to map or unmap rbd block devices, aka CID-f44d04e696fe. (CVE-2020-25284)\n\n - A race condition between hugetlb sysctl handlers in mm/hugetlb.c in the Linux kernel before 5.8.8 could be used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified other impact, aka CID-17743798d812.

(CVE-2019-19073)\n\n - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via\n crafted USB device traffic (which may be remote via usbip or usbredir). (CVE-2019-15505)\n\n - An issue was discovered in the Linux kernel before 5.4.7. The prb_calc_retire_blk_tmo() function in\n net/packet/af_packet.c can result in a denial of service (CPU consumption and soft lockup) in a certain\n failure case involving TPACKET_V3, aka CID-b43d1f9f7067. (CVE-2019-20812)\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 - fs/btrfs/volumes.c in the Linux kernel before 5.1 allows a btrfs_verify_dev_extents NULL pointer\n dereference via a crafted btrfs image because fs_devices->devices is mishandled within find_device, aka\n CID-09ba3bc9dd15. (CVE-2019-18885)\n\n - A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in\n crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4\n bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat,\n leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of\n service. (CVE-2020-10769)\n\n - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it\n incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly\n only validate the first netlink message in the skb and allow or deny the rest of the messages within the\n skb with the granted permission without further processing. (CVE-2020-10751)\n\n - An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An\n attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations\n before the required authentication process has completed. This could lead to different denial-of-service\n scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already\n existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge\n Authentication and Association Request packets to trigger this vulnerability. (CVE-2019-5108)\n\n - An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel\n through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable.\n This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an\n architecture for which this stack/DMA interaction has security relevance. (CVE-2019-17075)\n\n - An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a\n malicious USB device in the drivers/media/usb/siano/smsusb.c driver. (CVE-2019-15218)\n\n - A memory leak in the gs_can_open() function in drivers/net/can/usb/gs_usb.c in the Linux kernel before\n 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb()\n failures, aka CID-fb5be6a7b486. (CVE-2019-19052)\n\n - An issue was discovered in fs/gfs2/rgrp.c in the Linux kernel before 4.8. A use-after-free is caused by\n the functions gfs2_clear_rgrpd and read_rindex_entry. (CVE-2016-10905)\n\n - An issue was discovered in drivers/net/ethernet/arc/emac_main.c in the Linux kernel before 4.5. A use-\n after-free is caused by a race condition between the functions arc_emac_tx and arc_emac_tx_clean.\n (CVE-2016-10906)\n\n - The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel before 4.10.4 allows local\n users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling.\n (CVE-2017-8925)\n\n - A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file\n system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash\n the system if the directory exists. The highest threat from this vulnerability is to system availability.\n (CVE-2020-14314)\n\n - sound/core/seq_device.c in the Linux kernel before 4.13.4 allows local users to cause a denial of service\n (snd_rawmidi_dev_seq_free use-after-free and system crash) or possibly have unspecified other impact via a\n crafted USB device. (CVE-2017-16528)\n\n - The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel before 4.10.4 allows\n local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel\n memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer\n underflow. (CVE-2017-8924)\n\n - In driver_override_store and driver_override_show of bus.c, there is a possible double free due to\n improper locking. This could lead to local escalation of privilege with System execution privileges\n needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android\n ID: A-69129004 References: Upstream kernel. (CVE-2018-9415)\n\n - An issue was discovered in the Linux kernel before 4.20.2. An out-of-bounds access exists in the function\n build_audio_procunit in the file sound/usb/mixer.c. (CVE-2019-15927)\n\n - A flaw was found in the Linux kernel's implementation of GRO in versions before 5.2. This flaw allows an\n attacker with local access to crash the system. (CVE-2020-10720)\n\n - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers\n to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c\n instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. (CVE-2020-25212)\n\n - The rbd block device driver in drivers/block/rbd.c in the Linux kernel through 5.8.9 used incomplete\n permission checking for access to rbd devices, which could be leveraged by local attackers to map or unmap\n rbd block devices, aka CID-f44d04e696fe. (CVE-2020-25284)\n\n - A race condition between hugetlb sysctl handlers in mm/hugetlb.c in the Linux kernel before 5.8.8 could be\n used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified\n other impact, aka CID-17743798d812.

"2023-01-29T14:38:54", "description": "According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :\n\n - A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network(CVE-2019-3846)\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(CVE-2020-11608)\n\n - 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)\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 - An out-of-bounds write flaw was found in the Linux kernel. A crafted keycode table could be used by drivers/input/input.c to perform the out-of-bounds write. A local user with root access can insert garbage to this keycode table that can lead to out-of-bounds memory access. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2019-20636)\n\n - The kernel in Red Hat Enterprise Linux 7 and MRG-2 does not clear garbage data for SG_IO buffer, which may leaking sensitive information to userspace.(CVE-2014-8181)\n\n - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly only validate the first netlink message in the skb and allow or deny the rest of the messages within the skb with the granted permission without further processing.(CVE-2020-10751)\n\n - An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory, aka 'Windows Kernel Information Disclosure Vulnerability'.(CVE-2019-1125)\n\n - A memory leak in the ath10k_usb_hif_tx_sg() function in drivers/net/wireless/ath/ath10k/usb.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka CID-b8d17e7d93d2.(CVE-2019-19078)\n\n - A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data.(CVE-2020-10732)\n\n - In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered.(CVE-2020-24394)\n\n - The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c.(CVE-2020-16166)\n\n - In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff.(CVE-2020-25211)\n\n - In calc_vm_may_flags of ashmem.c, there is a possible arbitrary write to shared memory due to a permissions bypass. This could lead to local escalation of privilege by corrupting memory shared between processes, with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android ID: A-142938932(CVE-2020-0009)\n\n - In the Linux kernel through 5.7.6, usbtest_disconnect in drivers/usb/misc/usbtest.c has a memory leak, aka CID-28ebeb8db770.(CVE-2020-15393)\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 - 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 discovered in the Linux kernel through 5.7.1. drivers/tty/vt/keyboard.c has an integer overflow if k_ascii is called several times in a row, aka CID-b86dab054059. NOTE: Members in the community argue that the integer overflow does not lead to a security issue in this case.(CVE-2020-13974)\n\n - Insufficient input validation in Kernel Mode Driver in Intel(R) i915 Graphics for Linux before version 5.0 may allow an authenticated user to potentially enable escalation of privilege via local access.(CVE-2019-11085)\n\n - In the hidp_process_report in bluetooth, there is an integer overflow. This could lead to an out of bounds write with no additional execution privileges needed.\n User interaction is not needed for exploitation.\n Product: Android Versions: Android kernel Android ID:\n A-65853588 References: Upstream kernel.(CVE-2018-9363)\n\n - A flaw was found in the way mremap handled DAX Huge Pages. This flaw allows a local attacker with access to a DAX enabled storage to escalate their privileges on the system.(CVE-2020-10757)\n\n - A flaw was found in the Linux kernel. A heap based buffer overflow in mwifiex_uap_parse_tail_ies function in drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory corruption and possibly other consequences.(CVE-2019-10126)\n\n - A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause the system to crash or cause a denial of service.\n The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2020-25643)\n\n - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452.(CVE-2020-25212)\n\n - In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered.(CVE-2020-24394)\n\n - 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)\n\n - 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)\n\n - rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a certain upper-bound check, leading to a buffer overflow.(CVE-2019-17666)\n\n - The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source, the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver receives the firmware event frame from the host, the appropriate handler is called. This frame validation can be bypassed if the bus used is USB (for instance by a wifi dongle). This can allow firmware event frames from a remote source to be processed. In the worst case scenario, by sending specially-crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. More typically, this vulnerability will result in denial-of-service conditions.(CVE-2019-9503)\n\n - An issue was discovered in the Linux kernel before 5.0.4. The 9p filesystem did not protect i_size_write() properly, which causes an i_size_read() infinite loop and denial of service on SMP systems.(CVE-2019-16413)\n\n - An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable.\n This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an architecture for which this stack/DMA interaction has security relevance.(CVE-2019-17075)\n\n - drivers/net/wireless/ath/ath10k/usb.c in the Linux kernel through 5.2.8 has a NULL pointer dereference via an incomplete address in an endpoint descriptor.(CVE-2019-15099)\n\n - A flaw was found in the Linux kernel's freescale hypervisor manager implementation, kernel versions 5.0.x up to, excluding 5.0.17. A parameter passed to an ioctl was incorrectly validated and used in size calculations for the page size calculation. An attacker can use this flaw to crash the system, corrupt memory, or create other adverse security affects.(CVE-2019-10142)\n\n - The Broadcom brcmfmac WiFi driver prior to commit 1b5e2423164b3670e8bc9174e4762d297990deff is vulnerable to a heap buffer overflow. If the Wake-up on Wireless LAN functionality is configured, a malicious event frame can be constructed to trigger an heap buffer overflow in the brcmf_wowl_nd_results function. This vulnerability can be exploited with compromised chipsets to compromise the host, or when used in combination with CVE-2019-9503, can be used remotely.\n In the worst case scenario, by sending specially-crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. More typically, this vulnerability will result in denial-of-service conditions.(CVE-2019-9500)\n\n - In the Linux kernel 4.14 longterm through 4.14.165 and 4.19 longterm through 4.19.96 (and 5.x before 5.2), there is a use-after-free (write) in the i915_ppgtt_close function in drivers/gpu/drm/i915/i915_gem_gtt.c, aka CID-7dc40713618c. This is related to i915_gem_context_destroy_ioctl in drivers/gpu/drm/i915/i915_gem_context.c.(CVE-2020-7053)\n\n - A flaw was found in the Linux Kernel where an attacker may be able to have an uncontrolled read to kernel-memory from within a vm guest. A race condition between connect() and close() function may allow an attacker using the AF_VSOCK protocol to gather a 4 byte information leak or possibly intercept or corrupt AF_VSOCK messages destined to other clients.(CVE-2018-14625)\n\n - An issue was discovered in the Linux kernel before 5.0.5. There is a use-after-free issue when hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c.(CVE-2019-15917)\n\n - An issue was discovered in the Linux kernel before 4.20.15. The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller does not check for this, it will trigger a NULL pointer dereference. This will cause denial of service. This affects nfc_llcp_build_gb in net/nfc/llcp_core.c.(CVE-2019-12818)\n\n - There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.(CVE-2019-14816)\n\n - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via crafted USB device traffic (which may be remote via usbip or usbredir).(CVE-2019-15505)\n\n - There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.(CVE-2019-14814)\n\n - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a long SSID IE, leading to a Buffer Overflow.(CVE-2019-17133)\n\n - An issue was discovered in the Linux kernel before 5.2.3. Out of bounds access exists in the functions ath6kl_wmi_pstream_timeout_event_rx and ath6kl_wmi_cac_event_rx in the file drivers/net/wireless/ath/ath6kl/wmi.c.(CVE-2019-15926)\n\n - 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)\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 - An issue was discovered in the Linux kernel before 5.0.9. There is a use-after-free in atalk_proc_exit, related to net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and net/appletalk/sysctl_net_atalk.c.(CVE-2019-15292)\n\n - 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. 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 - In the Linux kernel, a certain net/ipv4/tcp_output.c change, which was properly incorporated into 4.16.12, was incorrectly backported to the earlier longterm kernels, introducing a new vulnerability that was potentially more severe than the issue that was intended to be fixed by backporting. Specifically, by adding to a write queue between disconnection and re-connection, a local attacker can trigger multiple use-after-free conditions. This can result in a kernel crash, or potentially in privilege escalation.(CVE-2019-15239)\n\n - The Linux kernel 4.x (starting from 4.1) and 5.x before 5.0.8 allows Information Exposure (partial kernel address disclosure), leading to a KASLR bypass.\n Specifically, it is possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP addresses. NOTE: this attack against KASLR became viable in 4.1 because IP ID generation was changed to have a dependency on an address associated with a network namespace.(CVE-2019-10639)\n\n - The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls.\n This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c.(CVE-2019-11599)\n\n - 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)\n\n - An issue was discovered in the Linux kernel before 4.20.2. An out-of-bounds access exists in the function build_audio_procunit in the file sound/usb/mixer.c.(CVE-2019-15927)\n\n - An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check the length of variable elements in a beacon head, leading to a buffer overflow.(CVE-2019-16746)\n\n - The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel before 5.0.8 has multiple race conditions.(CVE-2019-11486)\n\n - Insufficient access control in the Intel(R) PROSet/Wireless WiFi Software driver before version 21.10 may allow an unauthenticated user to potentially enable denial of service via adjacent access.(CVE-2019-0136)\n\n - 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)\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-2019-14815)\n\n - The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka 'KNOB') that can decrypt traffic and inject arbitrary ciphertext without the victim noticing.(CVE-2019-9506)\n\n - A memory leak in the ath9k_wmi_cmd() function in drivers/net/wireless/ath/ath9k/wmi.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-728c1e2a05e4.(CVE-2019-19074)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

If the Wake-up on Wireless\n LAN functionality is configured, a malicious event\n frame can be constructed to trigger an heap buffer\n overflow in the brcmf_wowl_nd_results function. This\n vulnerability can be exploited with compromised\n chipsets to compromise the host, or when used in\n combination with CVE-2019-9503, can be used remotely.\n In the worst case scenario, by sending\n specially-crafted WiFi packets, a remote,\n unauthenticated attacker may be able to execute\n arbitrary code on a vulnerable system. More typically,\n this vulnerability will result in denial-of-service\n conditions.(CVE-2019-9500)\n\n - In the Linux kernel 4.14 longterm through 4.14.165 and\n 4.19 longterm through 4.19.96 (and 5.x before 5.2),\n there is a use-after-free (write) in the\n i915_ppgtt_close function in\n drivers/gpu/drm/i915/i915_gem_gtt.c, aka\n CID-7dc40713618c. This is related to\n i915_gem_context_destroy_ioctl in\n drivers/gpu/drm/i915/i915_gem_context.c.(CVE-2020-7053)\n\n - A flaw was found in the Linux Kernel where an attacker\n may be able to have an uncontrolled read to\n kernel-memory from within a vm guest.

The nfc_llcp_build_tlv function in\n net/nfc/llcp_commands.c may return NULL. If the caller\n does not check for this, it will trigger a NULL pointer\n dereference. This will cause denial of service. This\n affects nfc_llcp_build_gb in\n net/nfc/llcp_core.c.(CVE-2019-12818)\n\n - There is heap-based buffer overflow in kernel, all\n versions up to, excluding 5.3, in the marvell wifi chip\n driver in Linux kernel, that allows local users to\n cause a denial of service(system crash) or possibly\n execute arbitrary code.(CVE-2019-14816)\n\n - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux\n kernel through 5.2.9 has an out-of-bounds read via\n crafted USB device traffic (which may be remote via\n usbip or usbredir).(CVE-2019-15505)\n\n - There is heap-based buffer overflow in Linux kernel,\n all versions up to, excluding 5.3, in the marvell wifi\n chip driver in Linux kernel, that allows local users to\n cause a denial of service(system crash) or possibly\n execute arbitrary code.(CVE-2019-14814)\n\n - In the Linux kernel through 5.3.2,\n cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c\n does not reject a long SSID IE, leading to a Buffer\n Overflow.(CVE-2019-17133)\n\n - An issue was discovered in the Linux kernel before\n 5.2.3. Out of bounds access exists in the functions\n ath6kl_wmi_pstream_timeout_event_rx and\n ath6kl_wmi_cac_event_rx in the file\n drivers/net/wireless/ath/ath6kl/wmi.c.(CVE-2019-15926)\n\n - In the Linux kernel 5.4.0-rc2, there is a\n use-after-free (read) in the __blk_add_trace function\n in kernel/trace/blktrace.c (which is used to fill out a\n blk_io_trace structure and place it in a per-cpu\n sub-buffer).(CVE-2019-19768)\n\n - An issue was discovered in the Linux kernel through\n 5.5.6. set_fdc in drivers/block/floppy.c leads to a\n wait_til_ready out-of-bounds read because the FDC index\n is not checked for errors before assigning it, aka\n CID-2e90ca68b0d2.(CVE-2020-9383)\n\n - An issue was discovered in the Linux kernel before\n 5.0.9.

The flaw could\n occur when the station attempts a connection\n negotiation during the handling of the remote devices\n country settings. This could allow the remote device to\n cause a denial of service (system crash) or possibly\n execute arbitrary code.(CVE-2019-14895)\n\n - In the Linux kernel, a certain net/ipv4/tcp_output.c\n change, which was properly incorporated into 4.16.12,\n was incorrectly backported to the earlier longterm\n kernels, introducing a new vulnerability that was\n potentially more severe than the issue that was\n intended to be fixed by backporting. Specifically, by\n adding to a write queue between disconnection and\n re-connection, a local attacker can trigger multiple\n use-after-free conditions. This can result in a kernel\n crash, or potentially in privilege\n escalation.(CVE-2019-15239)\n\n - The Linux kernel 4.x (starting from 4.1) and 5.x before\n 5.0.8 allows Information Exposure (partial kernel\n address disclosure), leading to a KASLR bypass.\n Specifically, it is possible to extract the KASLR\n kernel image offset using the IP ID values the kernel\n produces for connection-less protocols (e.g., UDP and\n ICMP). When such traffic is sent to multiple\n destination IP addresses, it is possible to obtain hash\n collisions (of indices to the counter array) and\n thereby obtain the hashing key (via enumeration). This\n key contains enough bits from a kernel address (of a\n static variable) so when the key is extracted (via\n enumeration), the offset of the kernel image is\n exposed. This attack can be carried out remotely, by\n the attacker forcing the target device to send UDP or\n ICMP (or certain other) traffic to attacker-controlled\n IP addresses. Forcing a server to send UDP traffic is\n trivial if the server is a DNS server. ICMP traffic is\n trivial if the server answers ICMP Echo requests\n (ping). For client targets, if the target visits the\n attacker's web page, then WebRTC or gQUIC can be used\n to force UDP traffic to attacker-controlled IP\n addresses. NOTE: this attack against KASLR became\n viable in 4.1 because IP ID generation was changed to\n have a dependency on an address associated with a\n network namespace.(CVE-2019-10639)\n\n - The coredump implementation in the Linux kernel before\n 5.0.10 does not use locking or other mechanisms to\n prevent vma layout or vma flags changes while it runs,\n which allows local users to obtain sensitive\n information, cause a denial of service, or possibly\n have unspecified other impact by triggering a race\n condition with mmget_not_zero or get_task_mm calls.\n This is related to fs/userfaultfd.c, mm/mmap.c,\n fs/proc/task_mmu.c, and\n drivers/infiniband/core/uverbs_main.c.(CVE-2019-11599)\n\n - A memory leak in the adis_update_scan_mode() function\n in drivers/iio/imu/adis_buffer.c in the Linux kernel\n before 5.3.9 allows attackers to cause a denial of\n service (memory consumption), aka\n CID-ab612b1daf41.(CVE-2019-19060)\n\n - An issue was discovered in the Linux kernel before\n 4.20.2. An out-of-bounds access exists in the function\n build_audio_procunit in the file\n sound/usb/mixer.c.(CVE-2019-15927)\n\n - An issue was discovered in net/wireless/nl80211.c in\n the Linux kernel through 5.2.17.

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)\n\n - ** RESERVED ** This candidate has been reserved by an\n organization or individual that will use it when\n announcing a new security problem. When the candidate\n has been publicized, the details for this candidate\n will be provided.(CVE-2019-14815)\n\n - The Bluetooth BR/EDR specification up to and including\n version 5.1 permits sufficiently low encryption key\n length and does not prevent an attacker from\n influencing the key length negotiation. This allows\n practical brute-force attacks (aka 'KNOB') that can\n decrypt traffic and inject arbitrary ciphertext without\n the victim noticing.(CVE-2019-9506)\n\n - A memory leak in the ath9k_wmi_cmd() function in\n drivers/net/wireless/ath/ath9k/wmi.c in the Linux\n kernel through 5.3.11 allows attackers to cause a\n denial of service (memory consumption), aka\n CID-728c1e2a05e4.(CVE-2019-19074)\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the EulerOS security advisory.

Specifically, by adding to a write queue between disconnection and re-connection, a local attacker can trigger multiple use-after-free conditions. This can result in a kernel crash, or potentially in privilege escalation. NOTE: this affects (for example) Linux distributions that use 4.9.x longterm kernels before 4.9.190 or 4.14.x longterm kernels before 4.14.139.(CVE-2019-15239)An issue was discovered in the Linux kernel before 5.0.9.

Out of bounds access exists in the functions ath6kl_wmi_pstream_timeout_event_rx and ath6kl_wmi_cac_event_rx in the file driverset/wireless/ath/ath6kl/wmi.c.(CVE-2019-15926)An issue was discovered in the Linux kernel before 4.20.2.\n An out-of-bounds access exists in the function build_audio_procunit in the file sound/usb/mixer.c.(CVE-2019-15927)An issue was discovered in the Linux kernel before 5.0.4. The 9p filesystem did not protect i_size_write() properly, which causes an i_size_read() infinite loop and denial of service on SMP systems.(CVE-2019-16413)ax25_create in net/ax25/af_ax25.c in the AF_AX25 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-0614e2b73768.(CVE-2019-17052)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)atalk_create in net/appletalk/ddp.c in the AF_APPLETALK 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-6cc03e8aa36c.(CVE-2019-17054)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)llcp_sock_create in net fc/llcp_sock.c in the AF_NFC 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-3a359798b176.(CVE-2019-17056)In uvc_parse_standard_control of uvc_driver.c, there is a possible out-of-bound read due to improper input validation. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-111760968.(CVE-2019-2101)A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network.(CVE-2019-3846)A flaw was found in the Linux kernel's vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS). Versions 3.10, 4.14 and 4.18 are vulnerable.(CVE-2019-3882)If the Wake-up on Wireless LAN functionality is configured in the brcmfmac driver, which only works with Broadcom FullMAC chipsets, a malicious event frame can be constructed to trigger a heap buffer overflow in the brcmf_wowl_nd_results() function. This vulnerability can be exploited by compromised chipsets to compromise the host, or when used in combination with another brcmfmac driver flaw (CVE-2019-9503), can be used remotely. This can result in a remote denial of service (DoS). Due to the nature of the flaw, a remote privilege escalation cannot be fully ruled out.(CVE-2019-9500)If the brcmfmac driver receives a firmware event frame from a remote source, the is_wlc_event_frame function will cause this frame to be discarded and not be processed. If the driver receives the firmware event frame from the host, the appropriate handler is called. This frame validation can be bypassed if the bus used is USB (for instance by a WiFi dongle). This can allow firmware event frames from a remote source to be processed and this can result in denial of service (DoS) condition.(CVE-2019-9503)The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka KNOB) that can decrypt traffic and inject arbitrary ciphertext without the victim noticing.(CVE-2019-9506)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.
