Description:

The SUSE Linux Enterprise 11 SP4 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-2020-12652: 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-2020-12653: 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-2020-12654: Fixed an issue in he wifi driver which could have allowed a remote AP to trigger a heap-based buffer overflow (bsc#1171202).
  • CVE-2020-10690: Fixed the race between the release of ptp_clock and cdev (bsc#1170056).

The following non-security bugs were fixed:
  • nfsd4: clean up open owners on OPEN failure (bsc#1154290).
  • random: always use batched entropy for get_random_u{32,64} (bsc#1164871).
