kernel: exec: Cleanup POSIX timers right after de_thread()

A flaw was found in the Linux kernel. When a multi-threaded program sets up a per-thread timer and executes a new program that subsequently fails during startup, the kernel can free timer memory while it remains referenced in an active queue. A local user could exploit this vulnerability to trigg...
