Security update for the Linux Kernel

The SUSE Linux Enterprise 12 GA LTSS kernel was updated to fix two issues.

This security bug was fixed:

  • CVE-2016-5195: Local privilege escalation using MAP_PRIVATE. It is reportedly exploited in the wild (bsc#1004418).

This non-security bug was fixed:

  • sched/core: Fix a race between try_to_wake_up() and a woken up task (bsc#1002165, bsc#1001419).

Описание

Race condition in mm/gup.c in the Linux kernel 2.x through 4.x before 4.8.3 allows local users to gain privileges by leveraging incorrect handling of a copy-on-write (COW) feature to write to a read-only memory mapping, as exploited in the wild in October 2016, aka "Dirty COW."
