Subject: [Bug nptl/13690] pthread_mutex_unlock potentially cause invalid access
Date: Fri, 20 Jun 2014 18:29:00 -0000	[thread overview]
Message-ID: <bug-13690-131-vrPtZuXVDp@http.sourceware.org/bugzilla/> (raw)

--- Comment #38 from Torvald Riegel <triegel at redhat dot com> ---
We already started looking at the implications and into possible fixes.  The
any accesses to the mutex' memory are the easy part of the problem of this. 
The fact that the futex_wake call can now hit reused memory (i.e., after
destruction of the mutex) is the trickier issue IMO.  More details on the
latter can be found in an email I sent a while ago to libc-alpha.
