CVE-2026-80608

Kernel use-after-free via premature IOMMU domain release

Published Aug 28, 2026 · Updated Aug 28, 2026

Use-after-free in Linux 7.1 allows attackers to access freed IOMMU-domain memory during AMD XDNA device removal. amdxdna_remove() frees xdna->domain before DRM releases all managed GEM objects, so later amdxdna_gem_obj_free() cleanup dereferences expired domain memory. The race requires nondefault force_iova mode, device removal, and delayed GEM-object cleanup; published material establishes no impact beyond invalid kernel-memory access.
