This leaves the\ntimer in an active state while the assigned object is released via\nsnd_usbmidi_free(), which ends up with a kernel warning when the debug\nconfiguration is enabled, as spotted by fuzzer.\n\nFor avoiding the problem, put timer_shutdown_sync() at\nsnd_usbmidi_free(), so that the timer can be killed properly.\nWhile we're at it, replace the existing timer_delete_sync() at the\ndisconnect callback with timer_shutdown_sync(), too.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/06513dd6d32c37d0364db8488cfdf3e14da238a8","https://git.kernel.org/stable/c/0718a78f6a9f04b88d0dc9616cc216b31c5f3cf1","https://git.kernel.org/stable/c/62066758d2ae169278e5d6aea5995b1b6f6ddeb5","https://git.kernel.org/stable/c/647410a7da46067953a53c0d03f8680eff570959","https://git.kernel.org/stable/c/c611b9e55174e439dcd85a72969b43a95f3827a4"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:04:28.436527499+00:00"},"epss":{"cve":"CVE-2025-38105","score":0.00191,"percentile":0.08662,"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).
