{"id":"GHSA-585q-cm62-757j","summary":"mnl has segmentation fault and invalid memory read in `mnl::cb_run`","details":"The function `mnl::cb_run` is marked as safe but exhibits unsound behavior when processing malformed Netlink message buffers.\n\nPassing a crafted byte slice to `mnl::cb_run` can trigger memory violations. 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.","aliases":["RUSTSEC-2025-0142"],"modified":"2026-02-10T16:30:09.738803Z","published":"2026-01-09T19:53:23Z","database_specific":{"github_reviewed_at":"2026-01-09T19:53:23Z","nvd_published_at":null,"cwe_ids":["CWE-125"],"severity":"LOW","github_reviewed":true},"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"}],"affected":[{"package":{"name":"mnl","ecosystem":"crates.io","purl":"pkg:cargo/mnl"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.3.1"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 0.3.0","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/01/GHSA-585q-cm62-757j/GHSA-585q-cm62-757j.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P"}]}
