Description:
The SUSE Linux Enterprise 12 SP5 RT kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2022-0435: Fixed remote stack overflow in net/tipc module that validate domain record count on input (bsc#1195254).
- CVE-2022-24448: Fixed an issue inside fs/nfs/dir.c if an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup (bnc#1195612).
- CVE-2021-3564: Fixed double-free memory corruption in the Linux kernel HCI device initialization subsystem that could have been used by attaching malicious HCI TTY Bluetooth devices. A local user could use this flaw to crash the system (bnc#1186207).
- CVE-2020-28097: Fixed out-of-bounds read in vgacon subsystem that mishandled software scrollback (bnc#1187723).
