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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/28d984a66b9e14be74986167b6ad40b5e0daf19a","https://git.kernel.org/stable/c/2e509ef60ee41a2da0deb062c262bb530143fb37","https://git.kernel.org/stable/c/84b205297fa15f97510342221d8c9a0119711478","https://git.kernel.org/stable/c/8dbfd8e32a13e116790780ed0be82b5a05eb9916","https://git.kernel.org/stable/c/c83e79c0842ed29860648bcce5022ef0ba5001c6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:17.453294893+00:00"},"epss":{"cve":"CVE-2026-80572","score":0.0012,"percentile":0.0184,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
