## Description

In the Linux kernel, the following vulnerability has been resolved: ALSA: 6fire: Fix UAF at error handling during probe Although 6fire driver had a few fixes for dealing with the early error handling during the probe phase, it forgot a pending URB before freeing the resources, which may lead to a UAF. This patch addresses it by doing the almost same cleanup procedure like the normal disconnect phase at the error path.
