This freed the message decoder while it was still in use, causing a use-after-free and a potentially exploitable crash. This vulnerability was fixed in Thunderbird 158.0.1.","cvssScore":5.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L","cwes":["CWE-416"],"vendors":[],"products":[],"references":[{"url":"https://bugzilla.mozilla.org/show_bug.cgi?id=2075530","tags":[]},{"url":"https://www.mozilla.org/security/advisories/mfsa2026-114/","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
