Vulnerability from github – Published: 2024-09-04 21:30 – Updated: 2024-10-10 18:31In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Fix opregion leak
Being part o the display, ideally the setup and cleanup would be done by display itself. However this is a bigger refactor that needs to be done on both i915 and xe. For now, just fix the leak:
