Kangjie Lu e634fc4866 netfilter: ip6t_srh: fix NULL pointer dereferences ...

[ Upstream commit 6d65561f3d ]

skb_header_pointer may return NULL. The current code dereference
its return values without a NULL check.

The fix inserts the checks to avoid NULL pointer dereferences.

Fixes: 202a8ff545 ("netfilter: add IPv6 segment routing header 'srh' match")
