CVE-2026-63884 is a potential use-after-free vulnerability in the Linux kernel Intel i915 graphics driver's TTM object-purge handling. During eviction of an object marked as no longer needed, ttm_bo_validate() can replace the bo->ttm object. If the driver obtains an i915_tt pointer before validation, subsequent purge processing can dereference a stale page-vector container, including its file-pointer field. The issue produced a general protection fault in i915_ttm_purge during heavy graphics activity on DG2 hardware. The fix defers obtaining the i915_tt pointer until after ttm_bo_validate() so that subsequent processing uses the current object.
