The do_change_type function in fs/namespace.c in the Linux kernel before 2.6.22 does not verify that the caller has the CAP_SYS_ADMIN capability, which allows local users to gain privileges or cause a denial of service by modifying the properties of a mountpoint.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
