What it is

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

net/mlx5e: kTLS, Fix crash in RX resync flow

For the TLS RX resync flow, we maintain a list of TLS contexts

that require some attention, to communicate their resync information

to the HW.

Here we fix list corruptions, by protecting the entries against

movements coming from resync_handle_seq_match(), until their resync

handling in napi is fully completed.
