SUSE-SU-2022:1668-1

The SUSE Linux Enterprise 12 SP5 RT kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

• CVE-2022-28748: Fixed memory lead over the network by ax88179_178a devices (bsc#1196018).
• CVE-2022-28356: Fixed a refcount leak bug found in net/llc/af_llc.c (bnc#1197391).
• CVE-2022-1516: Fixed null-ptr-deref caused by x25_disconnect (bsc#1199012).
• CVE-2022-1419: Fixed a concurrency use-after-free in vgemgemdumb_create (bsc#1198742).
• CVE-2022-1353: Fixed access controll to kernel memory in the pfkeyregister function in net/key/afkey.c (bnc#1198516).
• CVE-2022-1280: Fixed a use-after-free vulnerability in drmleaseheld in drivers/gpu/drm/drm_lease.c (bnc#1197914).
• CVE-2022-1011: Fixed a use-after-free flaw inside the FUSE filesystem in the way a user triggers write(). This flaw allowed a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation (bnc#1197343).
• CVE-2021-43389: Fixed an array-index-out-of-bounds flaw in the detachcapictr function in drivers/isdn/capi/kcapi.c (bnc#1191958).
• CVE-2021-38208: Fixed a denial of service (NULL pointer dereference and BUG) by making a getsockname call after a certain type of failure of a bind call (bnc#1187055).
• CVE-2021-20321: Fixed a race condition accessing file object in the OverlayFS subsystem in the way users do rename in specific way with OverlayFS. A local user could have used this flaw to crash the system (bnc#1191647).
• CVE-2021-20292: Fixed object validation prior to performing operations on the object in nouveausgdmacreate_ttm in Nouveau DRM subsystem (bnc#1183723).
• CVE-2019-20811: Fixed issue in rxqueueaddkobject() and netdevqueueaddkobject() in net/core/net-sysfs.c, where a reference count is mishandled (bnc#1172456).
• CVE-2018-7755: Fixed an issue in the fdlockedioctl function in drivers/block/floppy.c. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location of kernel code and data and bypass kernel security protections such as KASLR (bnc#1084513).
