CVE-2016-2853: Linux Kernel

High severity, CVSS 7.8. EPSS: 0.9% chance of exploitation in the next 30 days.

The aufs module for the Linux kernel 3.x and 4.x does not properly restrict the mount namespace, which allows local users to gain privileges by mounting an aufs filesystem on top of a FUSE filesystem, and then executing a crafted setuid program.

Affected products

• Linux Linux Kernel: from 3.0.0, up to and including 3.19.8; from 4.0.0, up to and including 4.20.15
