The count sizes two variable-length arrays on the thread stack with no upper bound, and the decoder then fills them with attacker-supplied values.","published":"2026-10-09T05:16:45.000Z","lastModified":"2026-10-09T17:16:50.000Z","status":"Deferred","sourceIdentifier":"33c584b5-0579-4c06-b2a0-8d8329fcab9c","cvss":{"version":"4.0","score":9.2,"severity":"CRITICAL","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-121"],"affected":[],"epss":{"score":0.00584,"percentile":0.47668,"date":"2026-10-26","history":[{"date":"2026-10-09","score":0.00584,"percentile":0.46298}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.58%).
