ipv6: dccp: fix out of bound access in dccp_v6_err()
[ Upstream commit 1aa9d1a0e7eefcc61696e147d123453fc0016005 ]
dccp_v6_err() does not use pskb_may_pull() and might access garbage.
We only need 4 bytes at the beginning of the DCCP header, like TCP,
so the 8 bytes pulled in icmpv6_notify() are more than enough.
