vulnerability:
- 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.
