Is your app affected by CVE-2026-80541?
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: 4.20
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:
drm/amdgpu: validate GEM_CREATE domain combinations
AMDGPU_GEM_CREATE checked domain bits against AMDGPU_GEM_DOMAIN_MASK,
but did not validate domain combinations. Userspace could combine
CPU|GTT|VRAM with DOORBELL, GDS, GWS, or OA, making
amdgpu_bo_placement_from_domain() exceed AMDGPU_BO_MAX_PLACEMENTS and
hit BUG_ON().
Allow combinations only within CPU/GTT/VRAM, and require non-CPU/GTT/
VRAM domains to be specified one at a time. Return -EINVAL for invalid
combinations in amdgpu_gem_create_ioctl().
v2: Rename helper from amdgpu_gem_domain_valid() to
amdgpu_gem_are_domains_valid() (Christian)
(cherry picked from commit db39852d0c39843cb02048dfb47e4b8c703e9080)
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.
