Summary
Security update for the Linux Kernel
Details

The SUSE Linux Enterprise 12 SP5 Azure 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-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).
  • CVE-2021-44733: Fixed a use-after-free exists in drivers/tee/teeshm.c in the TEE subsystem, that could have occured because of a race condition in teeshmgetfrom_id during an attempt to free a shared memory object (bnc#1193767).
