In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Kill timer properly at removal The USB-audio MIDI code initializes the timer, but in a rare case, the driver might be freed without the disconnect call. This leaves the timer in an active state while the assigned object is released via snd_usbmidi_free(), which ends up with a kernel warning when the debug configuration is enabled, as spotted by fuzzer. For avoiding the problem, put timer_shutdown_sync() at snd_usbmidi_free(), so that the timer can be killed properly. While we're at it, replace the existing timer_delete_sync() at the disconnect callback with timer_shutdown_sync(), too. A flaw was found in the Linux kernel's USB-audio MIDI driver. In a rare scenario, the driver may be freed without properly shutting down an associated timer. This can leave the timer in an active state while its assigned object is released, potentially leading to a kernel warning and a Denial of Service (DoS) condition for a local user.
