Deskripsi CVE
In the Linux kernel, the following vulnerability has been resolved:
USB: c67x00: fix use-after-free in c67x00_add_iso_urb()
When TD creation fails for the last packet of an isochronous URB,
c67x00_add_iso_urb() gives the URB back before updating the endpoint
scheduling state.
c67x00_giveback_urb() frees the URB private data, and the completion
callback may release the final URB reference. The following accesses to
urbp->ep_data, urb->interval, and urbp->cnt can therefore use freed
memory.
Update next_frame and cnt before giving back the failed final packet,
making the giveback the last operation that uses the URB and its private
data.
