CVE-2025-38105

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ALSA: usb-audio: Kill timer properly at removal<br /> <br /> The USB-audio MIDI code initializes the timer, but in a rare case, the<br /> driver might be freed without the disconnect call. This leaves the<br /> timer in an active state while the assigned object is released via<br /> snd_usbmidi_free(), which ends up with a kernel warning when the debug<br /> configuration is enabled, as spotted by fuzzer.<br /> <br /> For avoiding the problem, put timer_shutdown_sync() at<br /> snd_usbmidi_free(), so that the timer can be killed properly.<br /> While we&amp;#39;re at it, replace the existing timer_delete_sync() at the<br /> disconnect callback with timer_shutdown_sync(), too.
