This hides the error condition from the caller of\nregcache_init(), and can cause NULL pointer dereferences when the regcache\nis later accessed.","published":"2026-08-15T06:22:19.000Z","lastModified":"2026-10-26T16:17:22.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00198,"percentile":0.09435,"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.
