Summary
In the Linux kernel, the following vulnerability has been resolved: igc: 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 igc_poll() runs while the controller is being reset this can lead to the driver try to free a skb that was already freed. Log message: [ 101.525242] refcount_t: underflow; use-after-free.
