CVE-2025-40085

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ALSA: usb-audio: Fix NULL pointer deference in try_to_register_card<br /> <br /> In try_to_register_card(), the return value of usb_ifnum_to_if() is<br /> passed directly to usb_interface_claimed() without a NULL check, which<br /> will lead to a NULL pointer dereference when creating an invalid<br /> USB audio device. Fix this by adding a check to ensure the interface<br /> pointer is valid before passing it to usb_interface_claimed().
