Name of the Vulnerable Software and Affected Versions Ubuntu Linux version 6.8

Description AppArmor SAUCE patches fail to acquire a lock when modifying a linked list. This allows an unprivileged local user to trigger a race condition, which can lead to a use-after-free (UAF)—a situation where a program continues to use a pointer after it has been freed—and potentially result in arbitrary code execution.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
