Description

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.

Affected configurations

• linux linux kernel (>= 2.6.17 < 5.10.258) • linux linux kernel (>= 5.11 < 5.15.209) • linux linux kernel (>= 5.16 < 6.1.175) • linux linux kernel (>= 6.2 < 6.6.141) • linux linux kernel (>= 6.7 < 6.12.91) • linux linux kernel (>= 6.13 < 6.18.33) • linux linux kernel (>= 6.19 < 7.0.10) • linux linux kernel 7.1
