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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":8.8,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},{"score":7.8,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793716095135,"publishedAt":1793716095135,"references":[{"source":"CNA: VulnCheck","tags":["vendor-advisory"],"url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-pm86-cc75-q463"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/surrealdb/surrealdb/commit/17584a181979f04f2aaad867332c22db1caa511a"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/surrealdb-before-3.3.0-use-after-free-via-affinitypool-spawn-local-in-kv-backends"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
