+Subject: [PATCH] sock_diag: Fix out-of-bounds access to sock_diag_handlers[]
+
+Userland can send a netlink message requesting SOCK_DIAG_BY_FAMILY
+with a family greater or equal then AF_MAX -- the array size of
+sock_diag_handlers[]. The current code does not test for this
+condition therefore is vulnerable to an out-of-bound access opening
+doors for a privilege escalation.
