Answer in brief
CVE-2021-46911 records a Critical severity (CVSS 9.8) vulnerability in ch_ktls: Fix kernel panic. 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: ch_ktls: Fix kernel panic Taking page refcount is not ideal and causes kernel panic sometimes. It's better to take tx_ctx lock for the complete skb transmit, to avoid page cleanup if ACK received in middle.
