In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: use kvzalloc to allocate struct dc struct dc has grown large over time most of it the two inlined dcscratchspace copies and now sits close to the page allocator's 4 MiB contiguous allocation limit. Its actual siz...

PT-2026-70950

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the drm/amd/display component where the dc create function uses kzalloc to allocate struct dc. Because struct dc has increased in size, it can exceed the page...

CVE-2026-64130

CVE-2026-64130 concerns the Linux kernel memory tagging during allocation of huge zero folios. The issue arises when init_on_free and __GFP_ZEROTAGS are used together: during __free_pages_prepare() pages may be zeroed while allocations with __GFP_ZEROTAGS skip clearing tag memory, and for huge ze...
