Description:

The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2020-10768: Fixed an issue with the prctl() function which could have allowed indirect branch speculation even after it has been disabled (bsc#1172783).
  • CVE-2020-10767: Fixed an issue where the Indirect Branch Prediction Barrier (IBPB) would have been disabled when STIBP is unavailable or enhanced IBRS is available making the system vulnerable to spectre v2 (bsc#1172782).
  • CVE-2020-10766: Fixed an issue with Linux scheduler which could have allowed an attacker to turn off the SSBD protection (bsc#1172781).

  • xfs: Fix tail rounding in xfs_alloc_file_space() (bsc#1172049).

Special Instructions and Notes:

  • Please reboot the system after installing this update.
