CVE-2026-31681

CVE-2026-31681 affects the Linux kernel netfilter xt_multiport component. The issue is in ports_match_v1() where a non-zero pflags entry is treated as a range start, causing the end of the range to be consumed incorrectly and potentially reading past the last ports[] element when a malformed rule...
