CVE-2016-5195

CVSS v2.0

7.2

High

VectorAV:L/AC:L/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions Linux kernel versions 2.x through 4.8.2
Description A race condition in the mm/gup.c component allows local users to gain elevated privileges. This is achieved by leveraging the incorrect handling of the copy-on-write (COW) feature—a mechanism that allows multiple processes to share the same memory page until one modifies it—to write data into read-only memory mappings. This issue was exploited in the wild in October 2016 and is commonly known as Dirty COW.
Recommendations Update Linux kernel to version 4.8.3 or later.
