Is your app affected by CVE-2026-72304?
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: 6.4
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:
ASoC: SOF: ipc4-control: Fix TOCTOU in sof_ipc4_bytes_put
In sof_ipc4_bytes_put(), the copy size is derived from the old
data->size in the buffer rather than the incoming new data's size
field from ucontrol. If the new data has a different size, the copy
uses the wrong length: it may truncate valid data or copy stale bytes.
Fix by validating and using the incoming data's sof_abi_hdr.size from
ucontrol before copying.
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.
