CVE-2026-99209 Oct 28, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
drm/xe: skip eviction of a BO with no resource
xe_evict_flags() switches on tbo->resource->mem_type to choose an
eviction placement. An xe BO can reach eviction with no ttm.resource,
e.g. an imported dma-buf BO whose resource was freed during teardown
while its attachment is still live: the exporter then invalidates it via
xe_dma_buf_move_notify() -> xe_bo_evict(), and the switch dereferences a
NULL resource and faults.
