Subject: CVE Request: kernel - sock_diag: Fix out-of-bounds access to sock_diag_handlers[]
An unprivileged user can send a netlink message resulting in an
out-of-bounds access of the sock_diag_handlers[] array which, in turn,
allows userland to take over control while in kernel mode.
Patch (already in net/master):
http://thread.gmane.org/gmane.linux.network/260061
Affected versions:
v3.3 - v3.8
PoC is not attached this time but can be requested on demand. Hint:
Works well on Fedora 18, bypassing all mmap_min_addr checks. ;)
Thanks,
Mathias
