Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ALSA: usb-audio: Check endpoint numbers at parsing Scarlett2 mixer interfaces<br />
<br />
The Scarlett2 mixer quirk in USB-audio driver may hit a NULL<br />
dereference when a malformed USB descriptor is passed, since it<br />
assumes the presence of an endpoint in the parsed interface in<br />
scarlett2_find_fc_interface(), as reported by fuzzer.<br />
<br />
For avoiding the NULL dereference, just add the sanity check of<br />
bNumEndpoints and skip the invalid interface.
