    descriptionThe SUSE Linux Enterprise 12 SP5 azure kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2020-8834: KVM on Power8 processors had a conflicting use of HSTATE_HOST_R1 to store r1 state in kvmppc_hv_entry plus in kvmppc_{save,restore}_tm, leading to a stack corruption. Because of this, an attacker with the ability to run code in kernel space of a guest VM can cause the host kernel to panic (bnc#1168276). CVE-2020-11494: An issue was discovered in slc_bump in drivers/net/can/slcan.c, which allowed attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL (bnc#1168424). CVE-2020-10942: In 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 (bnc#1167629). CVE-2019-9458: In the video driver there was a use after free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed (bnc#1168295). CVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a system crash (bnc#1120386). CVE-2019-19770: Fixed a use-after-free in the debugfs_remove function (bsc#1159198). CVE-2020-11669: Fixed an issue where arch/powerpc/kernel/idle_book3s.S did not have save/restore functionality for PNV_POWERSAVE_AMR, PNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR (bnc#1169390). CVE-2020-8647: There was a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929). CVE-2020-8649: There was a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162931). CVE-2020-9383: An issue was discovered 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 (bnc#1165111). CVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bnc#1159285). CVE-2018-20836: Fixed an issue where a race condition in smp_task_timedout() and smp_task_done() could lead to a use-after-free (bnc#1134395). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionAl Viro discovered that the Linux kernel for s390x systems did not properly perform page table upgrades for kernel sections that use secondary address mode. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2020-11884) It was discovered that the Intel Wi-Fi driver in the Linux kernel did not properly check for errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-16234) Tristan Madani discovered that the block I/O tracing implementation in the Linux kernel contained a race condition. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2019-19768) It was discovered that the vhost net driver in the Linux kernel contained a stack buffer overflow. A local attacker with the ability to perform ioctl() calls on /dev/vhost-net could use this to cause a denial of service (system crash). (CVE-2020-10942) It was discovered that the virtual terminal implementation in the Linux kernel contained a race condition. A local attacker could possibly use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2020-8648) Shijie Luo discovered that the ext4 file system implementation in the Linux kernel did not properly check for a too-large journal size. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (soft lockup). (CVE-2020-8992) Jordy Zomer discovered that the floppy driver in the Linux kernel did not properly check for errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2020-9383).

    descriptionThe SUSE Linux Enterprise 12 SP4 azure kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2020-8834: KVM on Power8 processors had a conflicting use of HSTATE_HOST_R1 to store r1 state in kvmppc_hv_entry plus in kvmppc_{save,restore}_tm, leading to a stack corruption. Because of this, an attacker with the ability to run code in kernel space of a guest VM can cause the host kernel to panic (bnc#1168276). CVE-2020-11494: An issue was discovered in slc_bump in drivers/net/can/slcan.c, which allowed attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL (bnc#1168424). CVE-2020-10942: In 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 (bnc#1167629). CVE-2019-9458: In the video driver there was a use after free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed (bnc#1168295). CVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a system crash (bnc#1120386). CVE-2019-19770: Fixed a use-after-free in the debugfs_remove function (bsc#1159198). CVE-2020-11669: Fixed an issue where arch/powerpc/kernel/idle_book3s.S did not have save/restore functionality for PNV_POWERSAVE_AMR, PNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR (bnc#1169390). CVE-2020-8647: There was a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929). CVE-2020-8649: There was a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162931). CVE-2020-9383: An issue was discovered 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 (bnc#1165111). CVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bnc#1159285). The update package also includes non-security fixes. See advisory for details.

    descriptionThis update is now available for all supported architectures. For reference the original advisory text follows. Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2015-8839 A race condition was found in the ext4 filesystem implementation. A local user could exploit this to cause a denial of service (filesystem corruption). CVE-2018-14610, CVE-2018-14611, CVE-2018-14612, CVE-2018-14613 Wen Xu from SSLab at Gatech reported that crafted Btrfs volumes could trigger a crash (Oops) and/or out-of-bounds memory access. An attacker able to mount such a volume could use this to cause a denial of service or possibly for privilege escalation. CVE-2019-5108 Mitchell Frank of Cisco discovered that when the IEEE 802.11 (WiFi) stack was used in AP mode with roaming, it would trigger roaming for a newly associated station before the station was authenticated. An attacker within range of the AP could use this to cause a denial of service, either by filling up a switching table or by redirecting traffic away from other stations. CVE-2019-19319 Jungyeon discovered that a crafted filesystem can cause the ext4 implementation to deallocate or reallocate journal blocks. A user permitted to mount filesystems could use this to cause a denial of service (crash), or possibly for privilege escalation. CVE-2019-19447 It was discovered that the ext4 filesystem driver did not safely handle unlinking of an inode that, due to filesystem corruption, already has a link count of 0. An attacker able to mount arbitrary ext4 volumes could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation. CVE-2019-19768 Tristan Madani reported a race condition in the blktrace debug facility that could result in a use-after-free. A local user able to trigger removal of block devices could possibly use this to cause a denial of service (crash) or for privilege escalation. CVE-2019-20636 The syzbot tool found that the input subsystem did not fully validate keycode changes, which could result in a heap out-of-bounds write. A local user permitted to access the device node for an input or VT device could possibly use this to cause a denial of service (crash or memory corruption) or for privilege escalation. CVE-2020-0009 Jann Horn reported that the Android ashmem driver did not prevent read-only files from being memory-mapped and then remapped as read-write. However, Android drivers are not enabled in Debian kernel configurations. CVE-2020-0543 Researchers at VU Amsterdam discovered that on some Intel CPUs supporting the RDRAND and RDSEED instructions, part of a random value generated by these instructions may be used in a later speculative execution on any core of the same physical CPU. Depending on how these instructions are used by applications, a local user or VM guest could use this to obtain sensitive information such as cryptographic keys from other users or VMs. This vulnerability can be mitigated by a microcode update, either as part of system firmware (BIOS) or through the intel-microcode package in Debian

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service, or information leak. - CVE-2020-2732 Paulo Bonzini discovered that the KVM implementation for Intel processors did not properly handle instruction emulation for L2 guests when nested virtualization is enabled. This could allow an L2 guest to cause privilege escalation, denial of service, or information leaks in the L1 guest. - CVE-2020-8428 Al Viro discovered a use-after-free vulnerability in the VFS layer. This allowed local users to cause a denial-of-service (crash) or obtain sensitive information from kernel memory. - CVE-2020-10942 It was discovered that the vhost_net driver did not properly validate the type of sockets set as back-ends. A local user permitted to access /dev/vhost-net could use this to cause a stack corruption via crafted system calls, resulting in denial of service (crash) or possibly privilege escalation. - CVE-2020-11565 Entropy Moe reported that the shared memory filesystem (tmpfs) did not correctly handle an
