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

ALSA: usb-audio: stop parsing UAC2 rates at MAX_NR_RATES

parse_uac2_sample_rate_range() caps the number of enumerated
rates at MAX_NR_RATES, but it only breaks out of the current
rate loop. A malformed UAC2 RANGE response with additional
triplets continues parsing the remaining triplets and repeatedly
prints 'invalid uac2 rates' while probe still holds
register_mutex.

Stop the whole parse once the cap is reached and return the
number of rates collected so far.
