Description

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.
