This will cause a memory leak and denial of service.(CVE-2019-20095)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)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)In the Linux kernel before 5.1.6, there is a use-after-free in serial_ir_init_module() in drivers/media/rc/serial_ir.c.(CVE-2019-19543)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)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)A memory leak in the crypto_reportstat() function in drivers/virt/vboxguest/vboxguest_utils.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering copy_form_user() failures, aka CID-e0b0cb938864.(CVE-2019-19048)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 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)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. Confidentiality of data is the highest threat associated with this vulnerability.(CVE-2019-19338)In the Linux kernel 5.0.0-rc7 (as distributed in ubuntu/linux.git on kernel.ubuntu.com), mounting a crafted f2fs filesystem image and performing some operations can lead to slab-out-of-bounds read access in ttm_put_pages in drivers/gpu/drm/ttm/ttm_page_alloc.c.

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 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)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)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.\n An attacker can forge Authentication and Association Request packets to trigger this vulnerability.(CVE-2019-5108)drivers/gpu/drm/radeon/rad eon_display.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.(CVE-2019-16230)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

This will cause a memory leak and\n denial of service.(CVE-2019-20095)TSX Asynchronous\n Abort condition on some CPUs utilizing speculative\n execution may allow an authenticated user to\n potentially enable information disclosure via a side\n channel with local access.(CVE-2019-11135)A memory leak\n in the crypto_report() function in\n crypto/crypto_user_base.c in the Linux kernel through\n 5.3.11 allows attackers to cause a denial of service\n (memory consumption) by triggering crypto_report_alg()\n failures, aka CID-ffdde5932042.(CVE-2019-19062)In the\n Linux kernel before 5.1.6, there is a use-after-free in\n serial_ir_init_module() in\n drivers/media/rc/serial_ir.c.(CVE-2019-19543)In the\n Linux kernel through 5.4.6, there is a NULL pointer\n dereference in drivers/scsi/libsas/sas_discover.c\n because of mishandling of port disconnection during\n discovery, 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)An issue was\n discovered in drivers/xen/balloon.c in the Linux kernel\n before 5.2.3, as used in Xen through 4.12.x, allowing\n guest OS users to cause a denial of service because of\n unrestricted resource consumption during the mapping of\n guest memory, aka CID-6ef36ab967c7.(CVE-2019-17351)A\n memory leak in the crypto_reportstat() function in\n drivers/virt/vboxguest/vboxguest_utils.c in the Linux\n kernel before 5.3.9 allows attackers to cause a denial\n of service (memory consumption) by triggering\n copy_form_user() failures, aka\n CID-e0b0cb938864.(CVE-2019-19048)kernel/sched/fair.c in\n the 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 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)A flaw was found in the fix for\n CVE-2019-11135, the way Intel CPUs handle speculative\n execution of instructions when a TSX Asynchronous Abort\n (TAA) error occurs. When a guest is running on a host\n CPU affected by the TAA flaw (TAA_NO=0), but is not\n affected by the MDS issue (MDS_NO=1), the guest was to\n clear the affected buffers by using a VERW instruction\n mechanism. But when the MDS_NO=1 bit was exported to\n the guests, the guests did not use the VERW mechanism\n to clear the affected buffers. This issue affects\n guests running on Cascade Lake CPUs and requires that\n host has 'TSX' enabled. Confidentiality of data is the\n highest threat associated with this\n vulnerability.(CVE-2019-19338)In the Linux kernel\n 5.0.0-rc7 (as distributed in ubuntu/linux.git on\n kernel.ubuntu.com), mounting a crafted f2fs filesystem\n image and performing some operations can lead to\n slab-out-of-bounds read access in ttm_put_pages in\n drivers/gpu/drm/ttm/ttm_page_alloc.c. This is related\n to the vmwgfx or ttm module.(CVE-2019-19927)In the\n Linux kernel 4.14 longterm through 4.14.165 and 4.19\n longterm through 4.19.96 (and 5.x before 5.2), there is\n a use-after-free (write) in the i915_ppgtt_close\n function in 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 In the Linux kernel through 5.4.6, there are\n information leaks of uninitialized memory to a USB\n device in the\n driverset/can/usb/kvaser_usb/kvaser_usb_leaf.c driver,\n aka CID-da2311a6385c.(CVE-2019-19947)In the Linux\n kernel before 5.0.6, there is a NULL pointer\n dereference in drop_sysctl_table() in\n fs/proc/proc_sysctl.c, related to put_links, aka\n CID-23da9588037e.(CVE-2019-20054)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)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 heap-based buffer\n overflow was discovered 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 flaw could occur when the station\n attempts a connection negotiation during the handling\n of the remote devices country settings. This could\n allow the remote device to cause a denial of service\n (system crash) or possibly execute arbitrary\n code.(CVE-2019-14895)A stack-based buffer overflow was\n found in the Linux kernel, version kernel-2.6.32, in\n Marvell WiFi chip driver. An attacker is able to cause\n a denial of service (system crash) or, possibly execute\n arbitrary code, when a STA works in IBSS mode (allows\n connecting stations together without the use of an AP)\n and connects to another STA.(CVE-2019-14897)An\n exploitable denial-of-service vulnerability exists in\n the Linux kernel prior to mainline 5.3. An attacker\n could exploit this vulnerability by triggering AP to\n send IAPP location updates for stations before the\n required authentication process has completed. This\n could lead to different denial-of-service scenarios,\n either by causing CAM table attacks, or by leading to\n traffic flapping if faking already existing clients in\n other nearby APs of the same wireless infrastructure.\n An attacker can forge Authentication and Association\n Request packets to trigger this\n vulnerability.(CVE-2019-5108)drivers/gpu/drm/radeon/rad\n eon_display.c in the Linux kernel 5.2.14 does not check\n the alloc_workqueue return value, leading to a NULL\n pointer dereference.(CVE-2019-16230)\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the EulerOS security advisory.

"2023-05-18T15:03:23", "description": "The remote Oracle Linux 7 host has packages installed that are affected by multiple 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.

affected by the following vulnerabilities :\n\n - A heap-based buffer overflow was discovered in the Linux kernel's 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 - 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.

"description": "The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-4060 advisory.\n\n - An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. (CVE-2018-20836)\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 - 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 - 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 - In the Linux kernel before 5.0, a memory leak exists in sit_init_net() in net/ipv6/sit.c when register_netdev() fails to register sitn->fb_tunnel_dev, which may cause denial of service, aka CID-07f12b26e21a. (CVE-2019-16994)\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 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 - 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 - 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 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 - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16231)\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 - mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c in the Linux kernel before 5.1.6 has some error-handling cases that did not free allocated hostcmd memory, aka CID-003b686ace82. This will cause a memory leak and denial of service. (CVE-2019-20095)\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 - 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.\n (CVE-2020-10942)\n\n - An issue was discovered in the Linux kernel 3.16 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-2019-19046)\n\n - Multiple memory leaks in the iwl_pcie_ctxt_info_gen3_init() function in\n drivers/net/wireless/intel/iwlwifi/pcie/ctxt-info-gen3.c in the Linux kernel through 5.3.11 allow\n attackers to cause a denial of service (memory consumption) by triggering iwl_pcie_init_fw_sec() or\n dma_alloc_coherent() failures, aka CID-0f4f199443fa. (CVE-2019-19059)\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\n device in the drivers/usb/class/cdc-acm.c driver, aka CID-c52873e5a1ef. (CVE-2019-19530)\n\n - A flaw was found in the Linux kernel. An index buffer overflow during Direct IO write leading to the NFS\n client to crash. In some cases, a reach out of the index after one memory allocation by kmalloc will cause\n a kernel panic. The highest threat from this vulnerability is to data confidentiality and system\n availability. (CVE-2020-10742)\n\n - In the Android kernel in i2c driver there is a possible out of bounds write due to memory corruption. This\n could lead to local escalation of privilege with System execution privileges needed. User interaction is\n not needed for exploitation. (CVE-2019-9454)\n\n - In the Android kernel in the video driver there is a use after free due to a race condition. 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 - An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux\n kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause\n a denial of service (NULL pointer dereference and system crash). (CVE-2019-12614)\n\n - ** DISPUTED ** A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c\n in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by\n triggering nl80211hdr_put() failures, aka CID-1399c59fa929. NOTE: third parties dispute the relevance of\n this because it occurs on a code path where a successful allocation has already occurred. (CVE-2019-19055)\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 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\n do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in\n a different security domain. Exploitation limitations include the amount of elapsed time before an integer\n overflow occurs, and the lack of scenarios where signals to a parent process present a substantial\n operational threat. (CVE-2020-12826)\n\n - An out-of-bounds memory write flaw was found in how the Linux kernel's Voice Over IP H.323 connection\n tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote\n user to crash the system, causing a denial of service. The highest threat from this vulnerability is to\n confidentiality, integrity, as well as system availability.
