Answer in brief
CVE-2021-47215 records a Critical severity (CVSS 9.8) vulnerability in net/mlx5e: kTLS, Fix crash in RX resync flow. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 9.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
