CVE-2026-43436

   
Software afectado LINUX KERNEL
 
In the Linux kernel, the following vulnerability has been resolved:

ALSA: usb-audio: Check endpoint numbers at parsing Scarlett2 mixer interfaces

The Scarlett2 mixer quirk in USB-audio driver may hit a NULL
dereference when a malformed USB descriptor is passed, since it
assumes the presence of an endpoint in the parsed interface in
scarlett2_find_fc_interface(), as reported by fuzzer.

For avoiding the NULL dereference, just add the sanity check of
bNumEndpoints and skip the invalid interface.
