From 5518b29f225dbdf47ded02cf229ff8225a2cdf82 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Sun, 10 Oct 2010 22:46:34 +0000 Subject: [PATCH] ATM: mpc, fix use after free Stanse found that mpc_push frees skb and then it dereferences it. It is a typo, new_skb should be dereferenced there. Signed-off-by: Jiri Slaby Cc: Eric Dumazet Acked-by: Eric Dumazet Signed-off-by: David S.
