If the read fails, val_v remains\nuninitialized and its random stack content is subsequently reported\nas a measurement result.\n\nInitialize val_v to zero to ensure a predictable value is reported\nin case of bus failure and to prevent potential stack data leakage.\nThis also satisfies static analyzers that might otherwise flag the\nvariable as used uninitialized.","published":"2026-07-19T16:17:12.000Z","lastModified":"2026-07-27T17:44:24.000Z","status":"Awaiting Analysis","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00209,"percentile":0.10939,"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.
