NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-4.19 package and not the linux-4.19 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
