Description

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system. (CVE-2016-5195, Important)

Red Hat would like to thank Phil Oester for reporting this issue.
