Rust embedders that leak a dispatched future (e.g. via mem::forget) and drop the transaction cause pool workers to read and write freed memory, risking crashes or memory corruption.","published":"2026-11-03T15:17:31.553","modified":"2026-11-03T15:17:31.700","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/surrealdb/surrealdb/commit/17584a181979f04f2aaad867332c22db1caa511a","label":"surrealdb/surrealdb@17584a1"},"references":[{"type":"WEB","url":"https://github.com/surrealdb/surrealdb/commit/17584a181979f04f2aaad867332c22db1caa511a"},{"type":"WEB","url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-pm86-cc75-q463"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/surrealdb-before-3.3.0-use-after-free-via-affinitypool-spawn-local-in-kv-backends"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-03T15:17:31.700"}}
