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