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