Is your app affected by CVE-2026-74408?
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: 3.1
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:
wifi: ath9k: fix OOB access from firmware tx status queue ID
ath_tx_edma_tasklet() accesses sc->tx.txq[ts.qid] where ts.qid is a
4-bit hardware field (0-15), but the txq array only has
ATH9K_NUM_TX_QUEUES (10) entries. A qid >= 10 causes an OOB array
access.
Add a bounds check on ts.qid before using it as an array index.
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.
