The SUSE Linux Enterprise 15 SP1 LTSS 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-2022-0330: Fixed flush TLBs before releasing backing store (bsc#1194880).
