There is no network-facing component.\nAC:L - The attacker controls both sides of the race \u2014 arming the eviction-fence workers by allocating BOs and inducing TTM eviction, and freeing `amdgpu_fpriv` by closing the render fd \u2014 and can retry the open/allocate/close loop indefinitely at no cost. The path is active by default for any amdgpu client and does not depend on the non-default `amdgpu.user_queue` parameter.\nPR:L - Only an unprivileged local account with render-node access is needed; `AMDGPU_USERQ` and `AMDGPU_GEM_CREATE` are `DRM_RENDER_ALLOW`, and logind/Android ACLs grant `/dev/dri/renderD128` to the logged-in user by default. No root or capability check guards the eviction-fence suspend/restore worker path.\nUI:N - The attacking process performs every step itself \u2014 open the render node, create buffer objects, trigger eviction, close the fd. No action by another user is required.\nS:U - The corruption is confined to kernel slab memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a slab use-after-free on a 4096-byte `struct amdgpu_fpriv` (KASAN reports an 8-byte read of freed memory); an attacker who reclaims the slab controls the contents that are read back, yielding a kernel information-disclosure primitive.\nI:H - The freed object contains `work_struct` function pointers and a `timer_list` that the workqueue and timer subsystems subsequently dereference and call, so heap spraying the reclaimed kmalloc-4k object gives control-flow hijack and thus arbitrary kernel modification.\nA:H - Executing a work item and timer out of freed memory reliably causes a kernel oops or panic, as demonstrated by the KASAN slab-use-after-free report, and the race can be re-triggered repeatedly."
