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.)

"description": "According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is 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.

An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence.

(CVE-2019-17055)\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. 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 - 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 - 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 - An issue was discovered in drivers/scsi/qedi/qedi_dbg.c in the Linux kernel before 5.1.12. In the qedi_dbg_* family of functions, there is an out-of-bounds read. (CVE-2019-15090)\n\n - In the Linux kernel before 5.3.11, there is an info-leak bug that can be caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver, aka CID-f7a1337f0d29. (CVE-2019-19534)\n\n - 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 - 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 - An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel before 5.0.11. There is a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6. (CVE-2019-18805)\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 - 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.\n (CVE-2019-19074)\n\n - 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.)

"description": "According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :\n\n - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system:\n memory allocation, process allocation, device input and output, etc.Security Fix(es):In the Linux kernel 4.19.83, there is a use-after-free (read) in the debugfs_remove function in fs/debugfs/inode.c (which is used to remove a file or directory in debugfs that was previously created with a call to another debugfs function such as debugfs_create_file).(CVE-2019-19770)mwifiex_tm_cmd in driverset/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)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. This is related to the vmwgfx or ttm module.(CVE-2019-19927)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) In the Linux kernel through 5.4.6, there are information leaks of uninitialized memory to a USB device in the driverset/can/usb/kvaser_usb/kvaser_usb_leaf.c driver, aka CID-da2311a6385c.(CVE-2019-19947)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)In the Linux kernel before 5.1, there is a memory leak in\n __feat_register_sp() in net/dccp/feat.c, which may cause denial of service, aka CID-1d3ff0950e2b.(CVE-2019-20096)A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.(CVE-2019-14896)A 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.

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)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 is related\n to arch/powerpc/kernel/entry_64.S and\n arch/powerpc/kernel/security.c.(CVE-2019-18660)In the\n Linux kernel 5.0.21, mounting a crafted ext4 filesystem\n image, performing some operations, and unmounting can\n lead to a use-after-free in ext4_put_super in\n fs/ext4/super.c, related to dump_orphan_list in\n fs/ext4/super.c.(CVE-2019-19447)In the Linux kernel\n through 5.4.6, there is a NULL pointer dereference in\n drivers/scsi/libsas/sas_discover.c because of\n mishandling of port disconnection during discovery,\n related to a PHY down race condition, aka\n CID-f70267f379b5.(CVE-2019-19965)In the Linux kernel\n before 5.1.6, there is a use-after-free in cpia2_exit()\n in drivers/media/usb/cpia2/cpia2_v4l.c that will cause\n denial of service, aka\n CID-dea37a972655.(CVE-2019-19966)An exploitable\n denial-of-service vulnerability exists in the Linux\n kernel prior to mainline 5.3. An attacker could exploit\n this vulnerability by triggering AP to send IAPP\n location updates for stations before the required\n authentication process has completed. This could lead\n to different denial-of-service scenarios, either by\n causing CAM table attacks, or by leading to traffic\n flapping if faking already existing clients in other\n nearby APs of the same wireless infrastructure. An\n attacker can forge Authentication and Association\n Request packets to trigger this\n vulnerability.(CVE-2019-5108)mwifiex_tm_cmd in drivers/\n net/wireless/marvell/mwifiex/cfg80211.c in the Linux\n kernel before 5.1.6 has some error-handling cases that\n did not free allocated hostcmd memory, aka\n CID-003b686ace82. This will cause a memory leak and\n denial of service.(CVE-2019-20095)\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the EulerOS security advisory.

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 - An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario. (CVE-2019-3900)\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 - In the Linux kernel before 5.1.7, a device can be tracked by an attacker 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). An attack may be conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. (CVE-2019-10638)\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 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 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 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. 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 - 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 - 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.\n (CVE-2019-19074)\n\n - 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)\n\n - A flaw was found in the Linux kernel before 5.8-rc1 in the implementation of the Enhanced IBPB (Indirect Branch Prediction Barrier). The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect Branch Restricted Speculation (IBRS) is available. This flaw allows a local attacker to perform a Spectre V2 style attack when this configuration is active. The highest threat from this vulnerability is to confidentiality. (CVE-2020-10767)\n\n - In the Linux kernel before 5.2.9, there is an info-leak bug that can be caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_fd.c driver, aka CID-30a8beeb3042. (CVE-2019-19535)\n\n - An issue was discovered in the Linux kernel before 5.4.7. 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 - 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 flaw was found in the Linux Kernel before 5.8-rc6 in the ZRAM kernel module, where a user with a local account and the ability to read the /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device. With this vulnerability, continually reading the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making the system inoperable. (CVE-2020-10781)\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 - An issue was discovered in the Linux kernel through 4.17.10. There is an invalid pointer dereference in io_ctl_map_page() when mounting and operating a crafted btrfs image, because of a lack of block group item validation in check_leaf_item in fs/btrfs/tree-checker.c. (CVE-2018-14613)\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 pivot_root race condition in fs/namespace.c in the Linux kernel 4.4.x before 4.4.221, 4.9.x before 4.9.221, 4.14.x before 4.14.178, 4.19.x before 4.19.119, and 5.x before 5.3 allows local users to cause a denial of service (panic) by corrupting a mountpoint reference counter. (CVE-2020-12114)\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 - Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption), aka CID-3f9361695113. (CVE-2019-19063)\n\n - A memory leak in the bfad_im_get_stats() function in drivers/scsi/bfa/bfad_attr.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering bfa_port_get_stats() failures, aka CID-0e62395da2bd. (CVE-2019-19066)\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 - An issue was discovered in the Linux kernel through 5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c has a deadlock if a coalescing operation fails.

(CVE-2020-12114)\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 - Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c in the\n Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption), aka\n CID-3f9361695113. (CVE-2019-19063)\n\n - A memory leak in the bfad_im_get_stats() function in drivers/scsi/bfa/bfad_attr.c in the Linux kernel\n through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering\n bfa_port_get_stats() failures, aka CID-0e62395da2bd. (CVE-2019-19066)\n\n - A memory leak in the ath10k_usb_hif_tx_sg() function in drivers/net/wireless/ath/ath10k/usb.c in the Linux\n kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering\n usb_submit_urb() failures, aka CID-b8d17e7d93d2. (CVE-2019-19078)\n\n - An issue was discovered in the Linux kernel through 5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c\n has a deadlock if a coalescing operation fails. (CVE-2020-12771)\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\",

versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :\n\n - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system:\n memory allocation, process allocation, device input and output, etc. Security Fix(es):In the Linux kernel before 5.2.9, there is an info-leak bug that can be caused by a malicious USB device in the driverset/can/usb/peak_usb/pcan_usb_pro.c driver, aka CID-ead16e53c2f0.(CVE-2019-19536)In the Linux kernel before 5.2.9, there is an info-leak bug that can be caused by a malicious USB device in the driverset/can/usb/peak_usb/pcan_usb_fd.c driver, aka CID-30a8beeb3042.(CVE-2019-19535)vcs_write in drivers/tty/vt/vc_screen.c in the Linux kernel through 5.3.13 does not prevent write access to vcsu devices, aka CID-0c9acb1af77a.(CVE-2019-19252)In the AppleTalk subsystem in the Linux kernel before 5.1, there is a potential NULL pointer dereference because register_snap_client may return NULL. This will lead to denial of service in net/appletalk/aarp.c and net/appletalk/ddp.c, as demonstrated by unregister_snap_client, aka CID-9804501fa122.(CVE-2019-19227)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)In the Linux kernel before 5.3.11, there is an info-leak bug that can be caused by a malicious USB device in the driverset/can/usb/peak_usb/pcan_usb_core.c driver, aka CID-f7a1337f0d29.(CVE-2019-19534)In the Linux kernel before 5.3.11, there is a use-after-free bug that can be caused by a malicious USB device in the driverset/can/usb/mcba_usb.c driver, aka CID-4d6636498c41.(CVE-2019-19529)In the Linux kernel before 5.3.9, there is a use-after-free bug that can be caused by a malicious USB device in the driversfc/pn533/usb.c driver, aka CID-6af3aa57a098.(CVE-2019-19526)In the Linux kernel before 5.3.6, there is a use-after-free bug that can be caused by a malicious USB device in the driverset/ieee802154/atusb.c driver, aka CID-7fd25e6fc035.(CVE-2019-19525)In the Linux kernel before 5.3.9, there are multiple out-of-bounds write bugs that can be caused by a malicious USB device in the Linux kernel HID drivers, aka CID-d9d4b1e46d95.\n This affects drivers/hid/hid-axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c, drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c, drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c, drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c, drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid-tmff.c, and drivers/hid/hid-zpff.c.(CVE-2019-19532)In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/hid/usbhid/hiddev.c driver, aka CID-9c09b214f30e.(CVE-2019-19527)** DISPUTED ** The Linux kernel through 5.0.7, when CONFIG_IA32_AOUT is enabled and ia32_aout is loaded, allows local users to bypass ASLR on setuid a.out programs (if any exist) because install_exec_creds() is called too late in load_aout_binary() in fs/binfmt_aout.c, and thus the ptrace_may_access() check has a race condition when reading /proc/pid/stat. NOTE: the software maintainer disputes that this is a vulnerability because ASLR for a.out format executables has never been supported.(CVE-2019-11191)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)driverset/wireless/mar vell/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)driverset/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)** DISPUTED ** drivers/gpu/drm/amd/amdkfd/kfd_interrupt.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. NOTE: The security community disputes this issues as not being serious enough to be deserving a CVE id.(CVE-2019-16229)Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory entry lists.(CVE-2019-10220)A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system.(CVE-2019-14901)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)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)Linux Kernel could allow a local authenticated attacker to obtain sensitive information, caused by a Transaction Asynchronous Abort (TAA) h/w issue in KVM. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.(CVE-2019-19338)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)An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use this flaw to crash the system, resulting in a denial of service.(CVE-2019-19332)kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words, although this slice expiration would typically be seen with benign workloads, it is possible that an attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray requests. An attack does not affect the stability of the kernel it only causes mismanagement of application execution.)(CVE-2019-19922)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)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)In the Linux kernel through 5.4.6, there are information leaks of uninitialized memory to a USB device in the driverset/can/usb/kvaser_usb/kvaser_usb_leaf.c driver, aka CID-da2311a6385c.(CVE-2019-19947)In the Linux kernel before 5.1, there is a memory leak in\n __feat_register_sp() in net/dccp/feat.c, which may cause denial of service, aka CID-1d3ff0950e2b.(CVE-2019-20096)mwifiex_tm_cmd in driverset/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)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)In a Linux KVM guest that has PV TLB enabled, a process in the guest kernel may be able to read memory locations from another process in the same guest. This problem is limit to the host running linux kernel 4.10 with a guest running linux kernel 4.16 or later. The problem mainly affects AMD processors but Intel CPUs cannot be ruled out.(CVE-2019-3016)fsamei.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)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_tty.c.(CVE-2020-8648)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)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)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)In the Linux kernel 5.0.21, mounting a crafted ext4 filesystem image, performing some operations, and unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list in fs/ext4/super.c.(CVE-2019-19447)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)In the Linux kernel before 5.3.11, sound/core/timer.c has a use-after-free caused by erroneous code refactoring, aka CID-e7af6307a8a5. This is related to snd_timer_open and snd_timer_close_locked. The timeri variable was originally intended to be for a newly created timer instance, but was used for a different purpose after refactoring.(CVE-2019-19807)In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the\n __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)In the Linux kernel 5.0.21, mounting a crafted f2fs filesystem image can cause a NULL pointer dereference in f2fs_recover_fsync_data in fs/f2fs/recovery.c. This is related to F2FS_P_SB in fs/f2fs/f2fs.h.(CVE-2019-19815)** DISPUTED **\n __btrfs_free_extent in fs/btrfs/extent-tree.c in the Linux kernel through 5.3.12 calls btrfs_print_leaf in a certain ENOENT case, which allows local users to obtain potentially sensitive information about register values via the dmesg program. NOTE: The BTRFS development team disputes this issues as not being a vulnerability because '1) The kernel provide facilities to restrict access to dmesg - dmesg_restrict=1 sysctl option. So it's really up to the system administrator to judge whether dmesg access shall be disallowed or not. 2) WARN/WARN_ON are widely used macros in the linux kernel. If this CVE is considered valid this would mean there are literally thousands CVE lurking in the kernel\n - something which clearly is not the case.'(CVE-2019-19039)ext4_empty_dir in fs/ext4amei.c in the Linux kernel through 5.3.12 allows a NULL pointer dereference because ext4_read_dirblock(inode,0,DIRENT_HTREE) can be zero.(CVE-2019-19037)btrfs_root_node in fs/btrfs/ctree.c in the Linux kernel through 5.3.12 allows a NULL pointer dereference because rcu_dereference(root->node) can be zero.(CVE-2019-19036)In the Linux kernel 4.19.83, there is a use-after-free (read) in the debugfs_remove function in fs/debugfs/inode.c (which is used to remove a file or directory in debugfs that was previously created with a call to another debugfs function such as debugfs_create_file).(CVE-2019-19770)An issue was discovered in slc_bump in driverset/can/slcan.c in the Linux kernel through 5.6.2. It allows attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL, aka CID-b9258a2cece4.(CVE-2020-11494)An issue was discovered in the Linux kernel through 5.6.2.\n mpol_parse_str in mm/mempolicy.c has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-aa9f7d5172fa.(CVE-2020-11565)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)An issue was discovered in the stv06xx subsystem in the Linux kernel before 5.6.1. 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)An issue was discovered in the Linux kernel before 5.6.1.\n drivers/media/usb/gspca/ov519.c allows NULL pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs when there are zero endpoints, aka CID-998912346c0d.(CVE-2020-11608)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)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)An issue was discovered in the Linux kernel through 5.6.2.\n mpol_parse_str in mm/mempolicy.c has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-aa9f7d5172fa.(CVE-2020-0067)An issue was discovered in the Linux kernel before 5.2 on the powerpc platform.\n arch/powerpc/kernel/idle_book3s.S does not have save/restore functionality for PNV_POWERSAVE_AMR, PNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR, aka CID-53a712bae5dd.(CVE-2020-11669)A flaw was found in the Linux kernelaEUR?s implementation of GRO. This flaw allows an attacker with local access to crash the system.(CVE-2020-10720)A flaw was found in the Linux kernel's 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)An out-of-bounds (OOB) memory access flaw was found in ttm_put_pages in drivers/gpu/drm/ttm/ttm_page_alloc.c in the Linux kernel's graphics module.

(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)\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 5.1.6, 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)\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 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)\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 - 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 - Insufficient access control in subsystem for Intel (R) processor graphics in 6th, 7th, 8th and 9th Generation Intel(R) Core(TM) Processor Families Intel(R) Pentium(R) Processor J, N, Silver and Gold Series Intel(R) Celeron(R) Processor J, N, G3900 and G4900 Series Intel(R) Atom(R) Processor A and E3900 Series Intel(R) Xeon(R) Processor E3-1500 v5 and v6 and E-2100 Processor Families may allow an authenticated user to potentially enable denial of service via local access.(CVE-2019-0154)\n\n - Insufficient access control in a subsystem for Intel (R) processor graphics in 6th, 7th, 8th and 9th Generation Intel(R) Core(TM) Processor Families Intel(R) Pentium(R) Processor J, N, Silver and Gold Series Intel(R) Celeron(R) Processor J, N, G3900 and G4900 Series Intel(R) Atom(R) Processor A and E3900 Series Intel(R) Xeon(R) Processor E3-1500 v5 and v6, E-2100 and E-2200 Processor Families Intel(R) Graphics Driver for Windows before 26.20.100.6813 (DCH) or 26.20.100.6812 and before 21.20.x.5077 (aka15.45.5077), i915 Linux Driver for Intel(R) Processor Graphics before versions 5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201 may allow an authenticated user to potentially enable escalation of privilege via local access.(CVE-2019-0155)\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 - Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory entry lists.(CVE-2019-10220)\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.

An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack.\n The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. Kernel versions 4.18.x, 4.14.x and 3.10.x are believed to be vulnerable.(CVE-2018-14633)\n\n - A flaw was found in the Linux kernel.

Android ID:\n A-66954097.(CVE-2017-13216)\n\n - The acpi_ds_create_operands() function in\n drivers/acpi/acpica/dsutils.c in the Linux kernel\n through 4.12.9 does not flush the operand cache and\n causes a kernel stack dump, which allows local users to\n obtain sensitive information from kernel memory and\n bypass the KASLR protection mechanism (in the kernel\n through 4.9) via a crafted ACPI table.(CVE-2017-13693)\n\n - drivers/net/usb/pegasus.c in the Linux kernel 4.9.x\n before 4.9.11 interacts incorrectly with the\n CONFIG_VMAP_STACK option, which allows local users to\n cause a denial of service (system crash or memory\n corruption) or possibly have unspecified other impact\n by leveraging use of more than one virtual page for a\n DMA scatterlist.(CVE-2017-8068)\n\n - drivers/net/usb/rtl8150.c in the Linux kernel 4.9.x\n before 4.9.11 interacts incorrectly with the\n CONFIG_VMAP_STACK option, which allows local users to\n cause a denial of service (system crash or memory\n corruption) or possibly have unspecified other impact\n by leveraging use of more than one virtual page for a\n DMA scatterlist.(CVE-2017-8069)\n\n - drivers/net/usb/catc.c in the Linux kernel 4.9.x before\n 4.9.11 interacts incorrectly with the CONFIG_VMAP_STACK\n option, which allows local users to cause a denial of\n service (system crash or memory corruption) or possibly\n have unspecified other impact by leveraging use of more\n than one virtual page for a DMA\n scatterlist.(CVE-2017-8070)\n\n - A security flaw was found in the\n chap_server_compute_md5() function in the ISCSI target\n code in the Linux kernel in a way an authentication\n request from an ISCSI initiator is processed. An\n unauthenticated remote attacker can cause a stack\n buffer overflow and smash up to 17 bytes of the stack.\n The attack requires the iSCSI target to be enabled on\n the victim host. Depending on how the target's code was\n built (i.e. depending on a compiler, compile flags and\n hardware architecture) an attack may lead to a system\n crash and thus to a denial-of-service or possibly to a\n non-authorized access to data exported by an iSCSI\n target.

vulnerabilities :\n\n - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system:\n memory allocation, process allocation, device input and output, etc.Security Fix(es):In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/ net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls.(CVE-2020-10942)In the Linux kernel 5.0.21, a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call.(CVE-2019-19319)In kernel/compat.c in the Linux kernel before 3.17, as used in Google Chrome OS and other products, there is a possible out-of-bounds read. restart_syscall uses uninitialized data when restarting compat_sys_nanosleep. NOTE: this is disputed because the code path is unreachable.(CVE-2014-3180)In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-buffer).(CVE-2019-19768)There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c.(CVE-2020-8647)There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c.(CVE-2020-8649)drivers/g pu/drm/radeon/radeon_display.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. NOTE: A third-party software maintainer states that the work queue allocation is happening during device initialization, which for a graphics card occurs during boot. It is not attacker controllable and OOM at that time is highly unlikely.(CVE-2019-16230)There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the n_tty_receive_buf_common function in drivers/tty/ n_tty.c.(CVE-2020-8648)A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest.(CVE-2020-2732)An issue was discovered in the Linux kernel through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2.(CVE-2020-9383)ext4_protect_reserved_i node in fs/ext4/block_validity.c in the Linux kernel through 5.5.3 allows attackers to cause a denial of service (soft lockup) via a crafted journal size.(CVE-2020-8992)Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients.(CVE-2017-13080)Linux Kernel version 3.18 to 4.16 incorrectly handles an SG_IO ioctl on /dev/sg0 with dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte cmdp. This may lead to copying up to 1000 kernel heap pages to the userspace. This has been fixed upstream in https://github.com/torvalds/linux/commit/a45b599ad808c3 c982fdcdc12b0b8611c2f92824 already. The problem has limited scope, as users don't usually have permissions to access SCSI devices. On the other hand, e.g. the Nero user manual suggests doing `chmod o+r+w /dev/sg*` to make the devices accessible. NOTE: third parties dispute the relevance of this report, noting that the requirement for an attacker to have both the CAP_SYS_ADMIN and CAP_SYS_RAWIO capabilities makes it 'virtually impossible to exploit.'(CVE-2018-1000204)The Linux kernel through 5.3.13 has a start_offset+size Integer Overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allows local users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation.(CVE-2019-18675)arch/x86/kvm/emulate.c in the Linux kernel before 4.8.12 does not properly initialize Code Segment (CS) in certain error cases, which allows local users to obtain sensitive information from kernel stack memory via a crafted application.(CVE-2016-9756)Double free vulnerability in drivers/ net/usb/cdc_ncm.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (system crash) or possibly have unspecified other impact by inserting a USB device with an invalid USB descriptor.(CVE-2016-3951)Linux Kernel contains an out-of-bounds read flaw in the asn1_ber_decoder() function in lib/asn1_decoder.c that is triggered when decoding ASN.1 data. This may allow a remote attacker to disclose potentially sensitive memory contents.(CVE-2018-9383)Linux Kernel contains a flaw in the ip6_setup_cork() function in net/ipv6/ip6_output.c that is triggered when handling too small IPv6 MTU sizes. This may allow a local attacker to cause a crash or potentially gain elevated privileges.(CVE-2018-9389)In the Android kernel in the video driver there is a use after free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.(CVE-2019-9458)An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use this flaw to crash the system, resulting in a denial of service.(CVE-2019-19332)kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words, although this slice expiration would typically be seen with benign workloads, it is possible that an attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray requests. An attack does not affect the stability of the kernel it only causes mismanagement of application execution.)(CVE-2019-19922)An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.(CVE-2019-5108)A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.(CVE-2019-14896)A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA.(CVE-2019-14897)In the Linux kernel through 5.4.6, there is a NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition, aka CID-f70267f379b5.(CVE-2019-19965)In the Linux kernel before 5.1.6, there is a use-after-free in cpia2_exit() in drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service, aka CID-dea37a972655.(CVE-2019-19966)In the Linux kernel before 5.1, there is a memory leak in\n __feat_register_sp() in net/dccp/feat.c, which may cause denial of service, aka CID-1d3ff0950e2b.(CVE-2019-20096)In the Linux kernel before 5.0.6, there is a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c, related to put_links, aka CID-23da9588037e.(CVE-2019-20054)drivers/ net/usb/pegasus.c in the Linux kernel 4.9.x before 4.9.11 interacts incorrectly with the CONFIG_VMAP_STACK option, which allows local users to cause a denial of service (system crash or memory corruption) or possibly have unspecified other impact by leveraging use of more than one virtual page for a DMA scatterlist.(CVE-2017-8068)A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver.\n The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code.(CVE-2019-14895)The acpi_ds_create_operands() function in drivers/acpi/acpica/dsutils.c in the Linux kernel through 4.12.9 does not flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.(CVE-2017-13693)Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory entry lists.(CVE-2019-10220)A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root.

This may lead to copying up to\n 1000 kernel heap pages to the userspace. This has been\n fixed upstream in\n https://github.com/torvalds/linux/commit/a45b599ad808c3\n c982fdcdc12b0b8611c2f92824 already. The problem has\n limited scope, as users don't usually have permissions\n to access SCSI devices. On the other hand, e.g. the\n Nero user manual suggests doing `chmod o+r+w /dev/sg*`\n to make the devices accessible. NOTE: third parties\n dispute the relevance of this report, noting that the\n requirement for an attacker to have both the\n CAP_SYS_ADMIN and CAP_SYS_RAWIO capabilities makes it\n 'virtually impossible to exploit.'(CVE-2018-1000204)The\n Linux kernel through 5.3.13 has a start_offset+size\n Integer Overflow in cpia2_remap_buffer in\n drivers/media/usb/cpia2/cpia2_core.c because cpia2 has\n its own mmap implementation.

This may allow a local\n attacker to cause a crash or potentially gain elevated\n privileges.(CVE-2018-9389)In the Android kernel in the\n video driver there is a use after free due to a race\n condition. This could lead to local escalation of\n privilege with no additional execution privileges\n needed. User interaction is not needed for\n exploitation.(CVE-2019-9458)An out-of-bounds memory\n write issue was found in the Linux Kernel, version 3.13\n through 5.4, in the way the Linux kernel's KVM\n hypervisor handled the 'KVM_GET_EMULATED_CPUID'\n ioctl(2) request to get CPUID features emulated by the\n KVM hypervisor. A user or process able to access the\n '/dev/kvm' device could use this flaw to crash the\n system, resulting in a denial of\n service.(CVE-2019-19332)kernel/sched/fair.c in the\n Linux kernel before 5.3.9, when cpu.cfs_quota_us is\n used (e.g., with Kubernetes), allows attackers to cause\n a denial of service against non-cpu-bound applications\n by generating a workload that triggers unwanted slice\n expiration, aka CID-de53fd7aedb1. (In other words,\n although this slice expiration would typically be seen\n with benign workloads, it is possible that an attacker\n could calculate how many stray requests are required to\n force an entire Kubernetes cluster into a\n low-performance state caused by slice expiration, and\n ensure that a DDoS attack sent that number of stray\n requests. An attack does not affect the stability of\n the kernel it only causes mismanagement of application\n execution.)(CVE-2019-19922)An exploitable\n denial-of-service vulnerability exists in the Linux\n kernel prior to mainline 5.3. An attacker could exploit\n this vulnerability by triggering AP to send IAPP\n location updates for stations before the required\n authentication process has completed. This could lead\n to different denial-of-service scenarios, either by\n causing CAM table attacks, or by leading to traffic\n flapping if faking already existing clients in other\n nearby APs of the same wireless infrastructure. An\n attacker can forge Authentication and Association\n Request packets to trigger this\n vulnerability.(CVE-2019-5108)A heap-based buffer\n overflow vulnerability was found in the Linux kernel,\n version kernel-2.6.32, in Marvell WiFi chip driver. A\n remote attacker could cause a denial of service (system\n crash) or, possibly execute arbitrary code, when the\n lbs_ibss_join_existing function is called after a STA\n connects to an AP.(CVE-2019-14896)A stack-based buffer\n overflow was found in the Linux kernel, version\n kernel-2.6.32, in Marvell WiFi chip driver. An attacker\n is able to cause a denial of service (system crash) or,\n possibly execute arbitrary code, when a STA works in\n IBSS mode (allows connecting stations together without\n the use of an AP) and connects to another\n STA.(CVE-2019-14897)In the Linux kernel through 5.4.6,\n there is a NULL pointer dereference in\n drivers/scsi/libsas/sas_discover.c because of\n mishandling of port disconnection during discovery,\n related to a PHY down race condition, aka\n CID-f70267f379b5.(CVE-2019-19965)In the Linux kernel\n before 5.1.6, there is a use-after-free in cpia2_exit()\n in drivers/media/usb/cpia2/cpia2_v4l.c that will cause\n denial of service, aka\n CID-dea37a972655.(CVE-2019-19966)In the Linux kernel\n before 5.1, there is a memory leak in\n __feat_register_sp() in net/dccp/feat.c, which may\n cause denial of service, aka\n CID-1d3ff0950e2b.(CVE-2019-20096)In the Linux kernel\n before 5.0.6, there is a NULL pointer dereference in\n drop_sysctl_table() in fs/proc/proc_sysctl.c, related\n to put_links, aka\n CID-23da9588037e.(CVE-2019-20054)drivers/\n net/usb/pegasus.c in the Linux kernel 4.9.x before\n 4.9.11 interacts incorrectly with the CONFIG_VMAP_STACK\n option, which allows local users to cause a denial of\n service (system crash or memory corruption) or possibly\n have unspecified other impact by leveraging use of more\n than one virtual page for a DMA\n scatterlist.(CVE-2017-8068)A heap-based buffer overflow\n was discovered in the Linux kernel, all versions 3.x.x\n and 4.x.x before 4.18.0, in Marvell WiFi chip driver.\n The flaw could occur when the station attempts a\n connection negotiation during the handling of the\n remote devices country settings. This could allow the\n remote device to cause a denial of service (system\n crash) or possibly execute arbitrary\n code.(CVE-2019-14895)The acpi_ds_create_operands()\n function in drivers/acpi/acpica/dsutils.c in the Linux\n kernel through 4.12.9 does not flush the operand cache\n and causes a kernel stack dump, which allows local\n users to obtain sensitive information from kernel\n memory and bypass the KASLR protection mechanism (in\n the kernel through 4.9) via a crafted ACPI\n table.(CVE-2017-13693)Linux kernel CIFS implementation,\n version 4.9.0 is vulnerable to a relative paths\n injection in directory entry lists.(CVE-2019-10220)A\n heap overflow flaw was found in the Linux kernel, all\n versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi\n chip driver. The vulnerability allows a remote attacker\n to cause a system crash, resulting in a denial of\n service, or execute arbitrary code. The highest threat\n with this vulnerability is with the availability of the\n system. If code execution occurs, the code will run\n with the permissions of root. This will affect both\n confidentiality and integrity of files on the\n system.(CVE-2019-14901)In the AppleTalk subsystem in\n the Linux kernel before 5.1, there is a potential NULL\n pointer dereference because register_snap_client may\n return NULL.

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\nA 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)\n\nA 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. The CPU executes instructions in the critical-sections as transactions, while ensuring their atomic state. 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.

These patches address vulnerabilities in Oracle code and in third-party components included in Oracle products. These patches are usually cumulative, but each advisory describes only the security patches added since the previous Critical Patch Update Advisory. Thus, prior Critical Patch Update advisories should be reviewed for information regarding earlier published security patches. Refer to [\u201cCritical Patch Updates, Security Alerts and Bulletins\u201d](<https://www.oracle.com/security-alerts/>) for information about Oracle Security advisories. \n\n**Oracle continues to periodically receive reports of attempts to maliciously exploit vulnerabilities for which Oracle has already released security patches. In some instances, it has been reported that attackers have been successful because targeted customers had failed to apply available Oracle patches. Oracle therefore strongly recommends that customers remain on actively-supported versions and apply Critical Patch Update security patches without delay.**\n\nThis Critical Patch Update contains 391 new security patches across the product families listed below.
