CVE-2021-47215 Information

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.
