This allows local users     (with /dev/video0 access) to obtain read and write     permissions on kernel physical pages, which can     possibly result in a privilege     escalation.(CVE-2019-18675)A flaw was found in the way     signature calculation was handled by cephx     authentication protocol.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - 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:
    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
    __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.
    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)
