If the new data has a different size, the copy\nuses the wrong length: it may truncate valid data or copy stale bytes.\n\nFix by validating and using the incoming data's sof_abi_hdr.size from\nucontrol before copying.","published":"2026-08-15T06:22:03.000Z","lastModified":"2026-10-16T19:17:21.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":[],"epss":{"score":0.00163,"percentile":0.05499,"date":"2026-10-27","history":[]},"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 (0.16%).
