This clamps the index to 0 for safe array\naccess and forces the returned count to 0 speculatively when the index\nis out of bounds.\n\nWe do not need additional array_index_nospec() calls in evdev_get_mask()\nbecause evdev_get_mask_cnt() speculatively forces the count (and\nresulting xfer_size) to 0 for out-of-bounds types, preventing any\nspeculative memory access to client evmasks array.","published":"2026-08-22T16:16:43.000Z","lastModified":"2026-10-14T13:10:00.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.0019,"percentile":0.0857,"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.
