Is your app affected by CVE-2026-80593?
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: 2.6.32
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:
hwmon: (asus_atk0110) Check package count before accessing element
atk_ec_present() walks the management group package returned by the GGRP
ACPI method and, for each sub-package, reads its first element:
id = &obj->package.elements[0];
if (id->type != ACPI_TYPE_INTEGER)
without checking that the sub-package is non-empty. ACPICA allocates the
element array with exactly package.count entries, so for a sub-package
with a zero count this reads past the allocation.
The sibling function atk_debugfs_ggrp_open() performs the same access but
skips empty packages with a package.count check first. Add the same
check to atk_ec_present() so a malformed firmware package cannot trigger
an out-of-bounds read.
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.
