Synopsis: Important: kernel
Advisory ID: SLSA-2016:2105-1
Issue Date: 2016-10-25
CVE Numbers: CVE-2016-5195
--

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)
