Jann Horn 4b8a938e32 dccp: Fix out of bounds access in DCCP error handler ... commit 977ad86c2a upstream. There was a previous attempt to fix an out-of-bounds access in the DCCP error handlers, but that fix assumed that the error handlers only want to access the first 8 bytes of the DCCP header. Actually, they also look at the DCCP sequence number, which is stored beyond 8 bytes, so an explicit pskb_may_pull() is required. Fixes: 6706a97fec ("dccp: fix out of bound access in dccp_v4_err()") Fixes: 1aa9d1a0e7 ("ipv6: dccp: fix out of bound access in dccp_v6_err()") Cc: stable@vger.kernel.org Signed-off-by: Jann Horn <jannh@google.com> Reviewed-by: Kuniyuki Iwashima <kuniyu@amazon.com> Signed-off-by: David S.
