Description
In the Linux kernel, the following vulnerability has been resolved:
igb: Fix use-after-free error during reset
Cleans the next descriptor to watch (next_to_watch) when cleaning the
TX ring.
Failure to do so can cause invalid memory accesses. If igb_poll() runs
while the controller is reset this can lead to the driver try to free
a skb that was already freed.
(The crash is harder to reproduce with the igb driver, but the same
potential problem exists as the code is identical to igc)
