A malformed firmware response can return a different object\ntype or an empty buffer, and the direct ret->buffer.pointer dereference\ncan then access an invalid pointer.\n\nUse the typed _DSM helper, validate that the returned buffer contains at\nleast one byte, and free the ACPI object after reading it.","published":"2026-08-10T13:20:25.000Z","lastModified":"2026-08-17T06:17:43.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00209,"percentile":0.10994,"date":"2026-10-26","history":[]},"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.
