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: iwlwifi: Fix error code in iwl_op_mode_dvm_start()
Preserve the error code if iwl_setup_deferred_work() fails. The current
code returns ERR_PTR(0) (which is NULL) on this path. I believe the
missing error code potentially leads to a use after free involving
debugfs.
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.
