The encoder uses a fixed 64-entry stack array or, for larger counts, a heap array sized from the first pass. If the second pass exceeds that capacity, entries are written out of bounds before the counts are compared.\n\nThis corrupts stack or heap memory and can crash the process.","published":"2026-10-19T19:17:22.000Z","lastModified":"2026-10-19T20:50:18.000Z","status":"Awaiting Analysis","sourceIdentifier":"9b29abf9-4ab0-4765-b253-1875cd9b441e","cvss":null,"cwe":["CWE-787"],"affected":[],"epss":{"score":0.00171,"percentile":0.06474,"date":"2026-10-27","history":[{"date":"2026-10-20","score":0.00171,"percentile":0.06118}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
