Loading vulnerability…
CVE-2009-3547 is caused by multiple race conditions in the Linux kernel’s fs/pipe.c (kernels prior to 2.6.32-rc6). A local attacker can trigger the race by attempting to open an anonymous pipe through a /proc/*/fd/ pathname, leading to incorrect concurrent state handling that can result in a NULL pointer dereference and system crash, and in some circumstances can be leveraged for local privilege escalation.
