   An update that solves 7 vulnerabilities and has four fixes
   is now available.

Description:

   The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:

   - CVE-2020-0543: Fixed a side channel attack against special registers
     which could have resulted in leaking of read values to cores other than
     the one which called it. This attack is known as Special Register Buffer
     Data Sampling (SRBDS) or "CrossTalk" (bsc#1154824).
   - CVE-2020-12656: Fixed an improper handling of certain domain_release
     calls leadingch could have led to a memory leak (bsc#1171219).
   - CVE-2020-12654: Fixed an issue in he wifi driver which could have
     allowed a remote AP to trigger a heap-based buffer overflow
     (bsc#1171202).
   - CVE-2020-12653: Fixed an issue in the wifi driver which could have
     allowed local users to gain privileges or cause a denial of service
     (bsc#1171195).
   - CVE-2020-12652: Fixed an issue which could have allowed local users to
     hold an incorrect lock during the ioctl operation and trigger a race
     condition (bsc#1171218).
   - CVE-2020-12114: Fixed A pivot_root race condition which could have
     allowed local users to cause a denial of service (panic) by corrupting a
     mountpoint reference counter (bsc#1171098).
   - CVE-2020-10757: Fixed an issue where remaping hugepage DAX to anon mmap
     could have caused user PTE access (bsc#1172317).

   The following non-security bugs were fixed:

   - can, slip: Protect tty->disc_data in write_wakeup and close with RCU
     (bsc#1171698).
   - KEYS: allow reaching the keys quotas exactly (bsc#1171689).
   - KEYS: reaching the keys quotas correctly (bsc#1171689).
   - Revert "ipc,sem: remove uneeded sem_undo_list lock usage in exit_sem()"
     (bsc#1172221).
   - random: always use batched entropy for get_random_u{32,64} (bsc#1164871).
