Is your app affected by CVE-2026-72296?
Paste this prompt into Claude Code, Cursor or any AI coding tool: it runs a free Shippable scan of your project and fixes what it finds. Built with Lovable, Bolt or v0? Scan your live app. Or upload your package file.
Who is affected
- Linux Linux: 4.6
How to check
- Find out whether you run the affected product and which version, then compare it with the versions above.
How to fix
Copies a prompt for Claude Code, Cursor or Codex that asks it to check whether you run this product.
- Apply the vendor's update or mitigation from the references below. If there is none yet, limit exposure of the affected service until there is.
- If a vulnerable version was live, check your logs and rotate the secrets that server could read.
The advisory
In the Linux kernel, the following vulnerability has been resolved:
net: ife: require ETH_HLEN to be pullable in ife_decode()
ife decode may return after making only the outer IFE header and
metadata pullable. The caller then passes the decapsulated packet to
eth_type_trans(), which expects the inner Ethernet header to be
accessible from the linear data area.
With a malformed IFE frame, the inner Ethernet header may still be
shorter than ETH_HLEN in the linear area, which can lead to a crash in
the original code.
Fix this by extending the pull check in ife_decode() so that the inner
Ethernet header is also guaranteed to be pullable before returning.
Check your whole app
Dependencies are only half of it. Free and read-only: before you push, run npx shippable-dev scan localhost:3000 in your project folder, no account needed. For your live app, you prove it's yours with a one-line tag first.
