The advisory
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix amdgpu_hmm_range_get_pages
The notifier sequence must only be read once or otherwise we could work
with invalid pages.
While at it also fix the coding style, e.g. drop the pre-initialized
return value and use the common define for 2G range.
(cherry picked from commit c08972f555945cda57b0adb72272a37910153390)
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.
