Is your app affected by CVE-2026-72312?
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: 5.14
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:
octeontx2-af: fix VF bringup affecting PF promiscuous state
Mbox handling of nix_set_rx_mode for a VF with promiscuous and
all_multi flags set to false causes deletion of the PF's promiscuous
and allmulti MCAM rules. This occurs because the APIs that
enable/disable these rules operate only on the PF, even when the
mbox request is made via a VF interface.
Guard both rvu_npc_enable_allmulti_entry() and
rvu_npc_enable_promisc_entry() disable paths with an is_vf() check so
that a VF bringing up or tearing down its interface cannot inadvertently
clear the PF's MCAM rules.
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.
