Vulnerability Title
ALSA: usb-audio: Fix potential memory leaks
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix potential memory leaks When the driver hits -ENOMEM at allocating a URB or a buffer, it aborts and goes to the error path that releases the all previously allocated resources. However, when -ENOMEM hits at the middle of the sync EP URB allocation loop, the partially allocated URBs might be left without released, because ep->nurbs is still zero at that point. Fix it by setting ep->nurbs at first, so that the error handler loops over the full URB list.
