CVE-2017-10661

This PoC exploits a use-after-free (UAF) vulnerability in the Linux kernel 4.10 by racing timerfd_settime operations to trigger a UAF condition, detectable with KASan. It uses multithreading to manipulate timer contexts and induce a race condition.

This PoC exploits a race condition in the Linux kernel's timerfd subsystem (CVE-2017-10661) by creating multiple threads that manipulate timerfd settings concurrently, leading to a use-after-free vulnerability. The code demonstrates the exploit by triggering the race condition through repeated timerfd operations.
