02fb9764-1893-11ed-9b22-002590c1f29c	FreeBSD -- Memory disclosure by stale virtual memory mapping Problem Description: A particular case of memory sharing is mishandled in the virtual memory system. This is very similar to SA-21:08.vm, but with a different root cause. Impact: An unprivileged local user process can maintain a mapping of a page after it is freed, allowing that process to read private data belonging to other processes or the kernel.
