The function does not sufficiently validate the input buffer structure before processing, leading to out-of-bounds reads.\n\nThis vulnerability allows an attacker to cause a Denial of Service (segmentation fault) or potentially read unmapped memory by providing a malformed Netlink message.","published":"2026-01-09T19:53:23Z","modified":"2026-02-10T16:30:09.738803Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"mnl","fixedVersion":"0.3.1"}],"fix":{"url":"https://github.com/mullvad/mnl-rs/pull/21","label":"mullvad/mnl-rs#21"},"references":[{"type":"WEB","url":"https://github.com/mullvad/mnl-rs/issues/15"},{"type":"WEB","url":"https://github.com/mullvad/mnl-rs/pull/21"},{"type":"WEB","url":"https://github.com/mullvad/mnl-rs/commit/61929d11c13b6cc4f864840a586fd48c6fd20ad9"},{"type":"PACKAGE","url":"https://github.com/mullvad/mnl-rs"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2025-0142.html"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-02-10T16:30:09.738803Z"}}
