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.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","cwes":["CWE-416"],"vendors":[],"products":[],"references":[{"url":"https://github.com/surrealdb/surrealdb/commit/17584a181979f04f2aaad867332c22db1caa511a","tags":[]},{"url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-pm86-cc75-q463","tags":[]},{"url":"https://www.vulncheck.com/advisories/surrealdb-before-3.3.0-use-after-free-via-affinitypool-spawn-local-in-kv-backends","tags":[]},{"url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-pm86-cc75-q463","tags":[]}],"exploitRefs":[{"url":"https://github.com/surrealdb/surrealdb/commit/17584a181979f04f2aaad867332c22db1caa511a","tags":[]},{"url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-pm86-cc75-q463","tags":[]},{"url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-pm86-cc75-q463","tags":[]}],"hasPoc":true,"ai":null}
