{"id":"CVE-2025-38105","summary":"ALSA: usb-audio: Kill timer properly at removal","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: usb-audio: Kill timer properly at removal\n\nThe USB-audio MIDI code initializes the timer, but in a rare case, the\ndriver might be freed without the disconnect call.  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.","modified":"2026-04-02T12:47:48.269207Z","published":"2025-07-03T08:35:15.301Z","related":["SUSE-SU-2025:02846-1","SUSE-SU-2025:02853-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:02969-1","SUSE-SU-2025:02996-1","SUSE-SU-2025:02997-1","SUSE-SU-2025:03011-1","SUSE-SU-2025:03023-1","SUSE-SU-2025:20577-1","SUSE-SU-2025:20586-1","SUSE-SU-2025:20601-1","SUSE-SU-2025:20602-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38105.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0718a78f6a9f04b88d0dc9616cc216b31c5f3cf1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/62066758d2ae169278e5d6aea5995b1b6f6ddeb5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/647410a7da46067953a53c0d03f8680eff570959"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c611b9e55174e439dcd85a72969b43a95f3827a4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/efaf61052b8ff9ee8968912fbaf02c2847c78ede"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38105.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38105"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"c88469704d63787e8d44ca5ea1c1bd0adc29572d"},{"fixed":"efaf61052b8ff9ee8968912fbaf02c2847c78ede"},{"fixed":"647410a7da46067953a53c0d03f8680eff570959"},{"fixed":"c611b9e55174e439dcd85a72969b43a95f3827a4"},{"fixed":"62066758d2ae169278e5d6aea5995b1b6f6ddeb5"},{"fixed":"0718a78f6a9f04b88d0dc9616cc216b31c5f3cf1"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-38105.json"}}],"schema_version":"1.7.5"}
