The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to an internal file descriptor leak that can cause a newly-spawned container process (from runc exec) to have a working directory in the host filesystem namespace or a malicious image to allow a container process to gain access to the host filesystem through runc run. A remote attacker can trick the victim into loading a malicious image to bypass sandbox restrictions and execute arbitrary code on the host OS.
