  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\ndrm/xe: Don't allow evicting of BOs in same VM in array of VM binds\nAn array of VM binds can potentially evict other buffer objects (BOs)\nwithin the same VM under certain conditions, which may lead to NULL\npointer dereferences later in the bind pipeline. To prevent this, clear\nthe allow_res_evict flag in the xe_bo_validate call.\nv2:\n- Invert polarity of no_res_evict (Thomas)\n- Add comment in code explaining issue (Thomas)\n(cherry picked from commit 8b9ba8d6d95fe75fed6b0480bb03da4b321bea08)", "A flaw was found in the Linux kernel's Intel Xe GPU driver. During an array of VM bind operations, buffer objects (BOs) within the same VM can be incorrectly evicted under certain conditions. This eviction leads to NULL pointer dereferences later in the bind pipeline when the code attempts to access the evicted resources. A local user with access to Intel Xe GPU resources could trigger this condition, causing a kernel crash and denial of service." ],
  "statement" : "This vulnerability affects systems with Intel discrete GPUs using the Xe driver. Exploitation requires local access and the ability to perform GPU memory management operations. The impact is limited to denial of service through a kernel crash.",
