The SUSE Linux Enterprise 11 SP3 kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2019-16746: Fixed an improper check of the length of variable elements in a beacon head, leading to a buffer overflow (bsc#1152107). - CVE-2019-5108: Fixed a denial-of-service vulnerability caused by triggering AP to send IAPP location updates for stations before the required authentication process has completed (bnc#1159912). - CVE-2019-6133: Fixed an issue where the 'start time' protection mechanism could have been bypassed and therefore authorization decisions are improperly cached (bsc#1128172). - CVE-2020-0305: Fixed a race condition which could have led to local escalation of privilege (bsc#1174462). - CVE-2020-0404: Fixed a linked list corruption due to an unusual root cause (bsc#1176423). - CVE-2020-0431: Fixed an out of bounds write due to a missing bounds check (bsc#1176722). - CVE-2020-10732: Fixed an improper implementation of userspace core dumps which could have led to crash a trivial program and exfiltrate private kernel data (bsc#1171220). - CVE-2020-10769: Fixed a buffer over-read in the IPsec Cryptographic algorithm's module, authenc.

The following non-security bugs were fixed:
- CIFS: fix uninitialized memory access (bsc#1120326). - fs/xfs: fix f_ffree value for statfs when project quota is set (bsc#1165985). - net/x25: fix a race in x25_bind() (bsc#1178590). - net/x25: prevent a couple of overflows (bsc#1178590). - tty: fix memleak in alloc_pid (bsc#1179745).
