This does not wait for a running byd_clear_touch() callback, which\ndereferences the private data and its psmouse pointer.  A callback racing\nwith disconnect can therefore access the private data after it has been\nfreed.  The timer can also still be re-armed by byd_process_byte() while\nthe disconnect is in progress.\n\nUse timer_shutdown_sync() before freeing the private data: it waits for\na running callback and turns any later re-arm attempt into a no-op.","published":"2026-08-26T15:17:13.000Z","lastModified":"2026-10-16T20:18:01.000Z","status":"Received","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":0.0012,"percentile":0.0184,"date":"2026-10-27","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 (0.12%).
