When a caller passes NULL, uuid_parse() ->\n__uuid_parse() -> uuid_is_valid() dereferences the pointer, causing\na kernel panic:\n\n  |  Unable to handle kernel NULL pointer dereference at virtual address\n  |  0000000000000040\n  |  pc : uuid_parse+0x40/0xac\n  |  lr : ffa_partition_info_get+0x1c/0x94 [arm_ffa]\n\nAdd a NULL guard before uuid_parse() so a NULL argument returns\n-ENODEV instead of crashing. Callers are expected to always supply\na valid partition UUID, so NULL is not a supported input.","published":"2026-08-12T00:17:45.000Z","lastModified":"2026-08-19T17:20:50.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00173,"percentile":0.0671,"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.
