Summary

[none]

Details

In the Linux kernel, the following vulnerability has been resolved:

igb: Fix use-after-free error during reset

Cleans the next descriptor to watch (nexttowatch) 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)
