drm/amdgpu: zero-initialize GART table on allocation
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: zero-initialize GART table on allocation GART TLB is flushed after unmapping but not after mapping. Since amdgpu_bo_create_kernel() does not zero-initialize the buffer, when a sin…

drm/amdkfd: Fix out-of-bounds write in kfd_event_page_set()
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix out-of-bounds write in kfd_event_page_set() The kfd_event_page_set() function writes KFD_SIGNAL_EVENT_LIMIT * 8 bytes via memset without checking the buffer size parameter. Th…

drm/amdgpu: fix amdgpu_hmm_range_get_pages
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…

drm/i915: Fix potential UAF in TTM object purge
In the Linux kernel, the following vulnerability has been resolved: drm/i915: Fix potential UAF in TTM object purge TLDR: The bo->ttm object might be changed by calling ttm_bo_validate(), move casting it to an i915_tt object later to actually get the right po…
