Description

The SUSE Linux Enterprise 12 rt-kernel was updated to 3.12.69 to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2015-8962: Fixed a double free vulnerability in the SCSI subsystem that allowed local users to gain privileges or cause a denial of service (memory corruption and system crash) (bnc#1010501).
