CVE-2026-68234

A flaw was found in the Linux kernel's drm/amdgpu component. The amdgpubocreatereserved function unconditionally increments a pin counter for a Buffer Object BO even if it is already pinned. This occurs when the function is called multiple times with the same BO, such as during firmware buffer...

CVE-2026-68101

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. During the allocation or deallocation of a user pointer buffer object, a critical reference to its virtual memory object can become unavailable. This improper handling of memory submissions could lead to system instability or a denial ...

CVE-2026-68265

A flaw was found in the Linux kernel. Specifically, within the drm/xe/vm module, an out-of-bounds access can occur when handling the DRMXECONSULTMEMADVISEPREFLOC region for a Buffer Object BO Virtual Memory Area VMA. This happens because a value of -1 is incorrectly used as an index into a memory...

CVE-2026-68266 drm/xe: Hold a dma-buf reference for imported BOs

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Hold a dma-buf reference for imported BOs An imported dma-buf BO is created as a ttmbotypesg BO whose reservation object is the exporter's dmabuf-resv. The importer, however, only takes a dma-buf reference after a...

CVE-2026-68265

CVE-2026-68265 affects the Linux kernel, specifically the drm/xe/vm path. The issue arises when prefetching a BO VMA in the region DRM_XE_CONSULT_MEM_ADVISE_PREF_LOC, where the code uses the value as an index into region_to_mem_type[], causing an out-of-bounds access (value is -1). The remediatio...

CVE-2026-68234

The CVE describes a bug in drm/amdgpu where amdgpu_bo_create_reserved pins and reserves a BO even when a non-NULL pointer is passed, leading to pin_count increments on repeated uses and eventual BO leaks because teardown unpins only once. The fix makes pinning occur only at creation, so repeated ...
