CVE-2010-0622

First published: Tue Feb 09 2010(Updated: )

Description of problem: If the owner of a PI futex dies we fix up the pi_state and set pi_state-&gt;owner to NULL. When a malicious or just sloppy programmed user space application sets the futex value to 0 e.g. by calling pthread_mutex_init(), then the futex can be acquired again. A new waiter manages to enqueue itself on the pi_state w/o damage, but on unlock the kernel dereferences pi_state-&gt;owner and oopses. Prevent this by checking pi_state-&gt;owner in the unlock path. If pi_state-&gt;owner is not current we know that user space manipulated the futex value. Ignore the mess and return -EINVAL. This catches the above case and also the case where a task hijacks the futex by setting the tid value and then tries to unlock it.
