CVE-2016-5195 Open this link in a new tabHow to fix?
Upgrade RHEL:7 kernel-rt-debug to version 0:3.10.0-327.36.3.rt56.238.el7 or higher.
This issue was patched in RHSA-2016:2110.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug package and not the kernel-rt-debug package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
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."
