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.
AnalysisAI
NULL pointer dereference in the Linux kernel's ALSA USB-audio Scarlett2 mixer quirk allows a local low-privileged user to crash the kernel (denial of service) by presenting a malformed USB descriptor with zero endpoints. Affected systems running unpatched kernels from the initial commit onward through stable branches 6.1.x, 6.6.x, 6.12.x, 6.18.x, and 6.19.x are exposed whenever the USB-audio driver enumerates a crafted or emulated Scarlett2-type device. …
