There is no network, adjacent-radio, or physical-access path to this code.\nAC:L - Triggering is a single deterministic ioctl with an invalid domain bitmask (e.g. CPU|GTT|VRAM|DOORBELL); the attacker fully controls the domains field and needs no race, special memory layout, or victim state. Invalid combinations reliably exceed AMDGPU_BO_MAX_PLACEMENTS (3) and hit BUG_ON() on every attempt.\nPR:L - AMDGPU_GEM_CREATE is registered with DRM_AUTH|DRM_RENDER_ALLOW, so any local unprivileged user who can open the render node (default on desktops, ChromeOS, Steam Deck, and cloud GPU tenants via render/video group or ACL) can invoke it without real root or init-namespace capabilities.\nUI:N - The attacking process performs the GEM_CREATE ioctl itself; no other user must mount a filesystem, open a file, click a link, or take any other action for the invalid domain combination to reach amdgpu_bo_placement_from_domain() and panic the kernel.\nS:U - Impact is confined to host-kernel memory corruption and panic within the amdgpu/TTM driver; it does not cross a VM, IOMMU, or sandbox security boundary, and is standard local kernel privilege-escalation/DoS scope rather than a guest-to-host escape.\nC:H - Before BUG_ON(), amdgpu_bo_placement_from_domain() writes past the fixed placements[AMDGPU_BO_MAX_PLACEMENTS] array into adjacent amdgpu_bo fields (including struct ttm_placement) with attacker-influenced mem_type and flag values; this out-of-bounds write is memory corruption that could be leveraged for kernel info disclosure.\nI:H - The same out-of-bounds placement writes corrupt adjacent kernel heap objects in the amdgpu_bo allocation with partially attacker-controlled ttm_place contents; out-of-bounds writes into kernel structures are classed as high integrity impact and could enable further heap corruption or control-flow hijacking.\nA:H - Once placement count exceeds three the kernel hits BUG_ON(c > AMDGPU_BO_MAX_PLACEMENTS), causing an oops or panic; an unprivileged GPU client on shared AMD hardware (multi-user workstations or cloud GPU nodes) can repeatedly crash the entire host, denying service to all co-tenants."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
