Ubuntu.comUB:CVE-2021-47301CVE-2021-47301
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)
