   An update that solves three vulnerabilities and has one
   errata is now available.

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).
