In the Linux kernel, the following vulnerability has been resolved:

netfilter: xt_policy: fix strict mode inbound policy matching

match_policy_in() walks sec_path entries from the last transform to the
first one, but strict policy matching needs to consume info->pol[] in
the same forward order as the rule layout.

Derive the strict-match policy position from the number of transforms
already consumed so that multi-element inbound rules are matched
consistently.
