Description

A race condition during supplicant re-authentication may leave a stale ACL entry that persists in the system. If the AclAgent subsequently restarts, this stale entry may be applied to new supplicants, resulting in incorrect access control enforcement. User interaction (an AclAgent restart by an administrator) is required for the unintended behavior to take effect.
