CVE-2026-86287
Published Sep 7, 2026
Last updated 3 hours ago
- Description
- Net::IP::LPM versions before 1.12 for Perl accept malformed prefix lengths. Non-numeric and non-ASCII prefix lengths are accepted and treated as 0. Integers over 31 bits are silently truncated. A single malformed mask will poison the lookup table. The result is that the lookup will silently succeed for every address. An allow-list will allow every address, and a deny-list will block every address.
