What it is

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

ALSA: 6fire: Release resources at card release

The current 6fire code tries to release the resources right after the

call of usb6fire_chip_abort(). But at this moment, the card object

might be still in use (as we're calling snd_card_free_when_closed()).

For avoid potential UAFs, move the release of resources to the card's

private_free instead of the manual call of usb6fire_chip_destroy() at

the USB disconnect callback.
