The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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 pointer. A user     reported hitting the following bug under heavy use on DG2: [26620.095550] Oops: general protection fault,     probably for non-canonical address 0xa56b6b6b6b6b6b8b: 0000 1 SMP NOPTI [26620.095556] CPU: 2 UID: 0 PID:

That path is taken when the object is marked as no longer needed. Code analysis     revealed a possibility of the i915 TTM page vector container being replaced with a new instance inside a     function that purges content of the object, should it be still busy. That function is called, indirectly     via a more general function that changes the object's placement and caching policy, ---truncated---     (CVE-2026-63884)
