Descriptions

In the Linux kernel, the following vulnerability has been resolved:

ALSA: usb-audio: Fix an out-of-bounds bug in __snd_usb_parse_audio_interface()

There may be a bad USB audio device with a USB ID of (0x04fa, 0x4201) and
the number of it's interfaces less than 4, an out-of-bounds read bug occurs
when parsing the interface descriptor for this device.

Fix this by checking the number of interfaces.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ALSA: usb-audio: corrige un error fuera de los límites en __snd_usb_parse_audio_interface() Puede haber un dispositivo de audio USB defectuoso con una ID de USB de (0x04fa, 0x4201) y el Si el número de interfaces es inferior a 4, se produce un error de lectura fuera de límites al analizar el descriptor de interfaz para este dispositivo. Solucione este problema verificando la cantidad de interfaces.
