tag_insight = "Pipes are a form of inter-process communication (IPC) provided by the
FreeBSD kernel.  kqueue is an event management API that applications can
use to monitor pipes and other kernel services.

A race condition exists in the pipe close() code relating to kqueues,
causing use-after-free for kernel memory, which may lead to an
exploitable NULL pointer vulnerability in the kernel, kernel memory
corruption, and other unpredictable results.";
