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

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

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

parseuac2sampleraterange() caps the number of enumerated rates at MAXNRRATES, 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.
