Summary

[none]

Details

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

bnxt: prevent skb UAF after handing over to PTP worker

When reading the timestamp is required bnxttxint() hands over the ownership of the completed skb to the PTP worker. The skb should not be used afterwards, as the worker may run before the rest of our code and free the skb, leading to a use-after-free.

Since devkfreeskb_any() accepts NULL make the loss of ownership more obvious and set skb to NULL.
