    descriptionThe SUSE Linux Enterprise 12 SP4 Azure kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2020-2732: Fixed an issue affecting Intel CPUs where an L2 guest may trick the L0 hypervisor into accessing sensitive L1 resources (bsc#1163971). CVE-2020-8992: An issue was discovered in ext4_protect_reserved_inode in fs/ext4/block_validity.c that allowed attackers to cause a soft lockup via a crafted journal size (bnc#1164069). CVE-2020-8648: There was a use-after-free vulnerability in the n_tty_receive_buf_common function in drivers/tty/n_tty.c (bnc#1162928). CVE-2020-8428: There was a use-after-free bug in fs/namei.c, which allowed local users to cause a denial of service or possibly obtain sensitive information from kernel memory (bnc#1162109). CVE-2020-7053: There was a use-after-free (write) in the i915_ppgtt_close function in drivers/gpu/drm/i915/i915_gem_gtt.c (bnc#1160966). CVE-2019-19045: A memory leak in drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c allowed attackers to cause a denial of service (memory consumption) by triggering mlx5_vector2eqn() failures (bnc#1161522). CVE-2019-16994: A memory leak existed in sit_init_net() in net/ipv6/sit.c which might have caused denial of service (bnc#1161523). CVE-2019-19054: A memory leak in the cx23888_ir_probe() function in drivers/media/pci/cx23885/cx23888-ir.c allowed attackers to cause a denial of service (memory consumption) by triggering kfifo_alloc() failures (bnc#1161518). CVE-2019-14896: A heap overflow was found in the add_ie_rates() function of the Marvell Wifi Driver (bsc#1157157). CVE-2019-14897: A stack overflow was found in the lbs_ibss_join_existing() function of the Marvell Wifi Driver (bsc#1157155). CVE-2019-19318: Mounting a crafted btrfs image twice could have caused a use-after-free (bnc#1158026). CVE-2019-19036: An issue discovered in btrfs_root_node in fs/btrfs/ctree.c allowed a NULL pointer dereference because rcu_dereference(root->node) can be zero (bnc#1157692). CVE-2019-14615: An information disclosure vulnerability existed due to insufficient control flow in certain data structures for some Intel(R) Processors (bnc#1160195). CVE-2019-19965: There was a NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition (bnc#1159911). CVE-2019-20095: Fixed a memory leak and denial of service in mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c, where some error-handling cases did not free allocated hostcmd memory (bnc#1159909). CVE-2019-20054: Fixed a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c related to put_links (bnc#1159910). CVE-2019-20096: Fixed a memory leak in __feat_register_sp() in net/dccp/feat.c, which may cause denial of service (bnc#1159908). CVE-2019-19966: Fixed a use-after-free in cpia2_exit() in drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service (bnc#1159841). CVE-2019-19447: Mounting a crafted ext4 filesystem image, performing some operations, and unmounting could have led to a use-after-free in fs/ext4/super.c (bnc#1158819). CVE-2019-19319: A setxattr operation, after a mount of a crafted ext4 image, could cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call (bnc#1158021). CVE-2019-19767: The Linux kernel mishandled ext4_expand_extra_isize, as demonstrated by use-after-free errors in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c (bnc#1159297). CVE-2019-18808: A memory leak in the ccp_run_sha_cmd() in drivers/crypto/ccp/ccp-ops.c allowed attackers to cause a denial of service (memory consumption) (bnc#1156259). CVE-2019-19066: A memory leak in the bfad_im_get_stats() in drivers/scsi/bfa/bfad_attr.c allowed attackers to cause a denial of service (memory consumption) by triggering bfa_port_get_stats() failures (bnc#1157303). The update package also includes non-security fixes. See advisory for details.

    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - drivers/gpu/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) - 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) - 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) - 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 n_tty_receive_buf_common function in drivers/tty/n_tty.c.(CVE-2020-8648) - 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) - ext4_protect_reserved_inode in fs/ext4/block_validity.c in the Linux kernel through 5.5.3 allows attackers to cause a denial of service (soft lockup) via a crafted journal size.(CVE-2020-8992) - 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) - 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) - 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) - 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

    descriptionAccording 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
