The counter has no dedicated synchronization mechanism,\nresulting in a potential data race when concurrently opening a device.\n\nThe race is a regression introduced by commit 8590222e4b02 (\"HID:\nhidraw: Replace hidraw device table mutex with a rwsem\"). While\nminors_rwsem is intended to protect the hidraw_table itself, by instead\nacquiring the lock for writing, the reference counter is also protected.\nThis is symmetrical to hidraw_release().","published":"2025-12-08T02:15:52.000Z","lastModified":"2026-08-04T10:19:20.000Z","status":"Deferred","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":[],"epss":{"score":0.00142,"percentile":0.0352,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.14%).
