Description
A vulnerability in the Linux kernel ALSA virtio driver was fixed by ensuring the device is reset before deleting virtqueues. Previously, virtqueues were deleted before resetting the device, which could allow the device to access freed vring memory. The fix involves resetting the device first to prevent access to released memory, covering normal operation and probe failure cases.
