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)
A flaw was found in the Linux kernel, specifically within the drm/amdgpu component. This vulnerability arises from incorrect handling of a notifier sequence in the amdgpu_hmm_range_get_pages function, where the sequence can be read more than once. This can lead to the system processing invalid memory pages, potentially resulting in system instability or crashes.
