If panfrost_priv has been\nfreed this is a use-after-free which I've been able to trigger resulting\nin a splat.\n\nTo fix this, drop the reference to panfrost_priv in the job structure\nand add a direct reference to the MMU structure which is what's actually\nneeded."

"value": "AV:L - The bug is reached via DRM ioctls (DRM_IOCTL_PANFROST_SUBMIT) and close() on the Panfrost render node (/dev/dri/renderD*), which requires local process access to the device file rather than network or adjacent-network input.\nAC:L - An attacker controls both sides by submitting GPU jobs then closing the FD; panfrost_postclose frees file_priv while in-flight/hard-stopped jobs still dereference it on the IRQ completion path, and the author reproduced the UAF splat without depending on uncontrolled conditions.\nPR:L - Panfrost ioctls are marked DRM_RENDER_ALLOW on a render node that grants GPU access to unprivileged clients (e.g., Android apps or desktop users with render-node access) without root or DRM master authentication.\nUI:N - The attacker opens the render node, submits jobs, and closes their own FD; no separate victim action is required.\nS:U - Impact is confined to the host kernel authority (heap UAF / potential local privilege escalation); this is not a VM escape or IOMMU/DMA security-boundary bypass.\nC:H - Use-after-free of panfrost_file_priv lets an attacker reclaim the object and corrupt the mmu pointer used by panfrost_mmu_as_get/put, enabling arbitrary kernel memory disclosure per UAF exploitation guidance.\nI:H - The same reclaimed file_priv/MMU pointer is consumed by job submit and IRQ completion paths that mutate MMU address-space state, yielding a controllable write/control-flow primitive suitable for integrity compromise and code execution.\nA:H - Dereferencing the freed file_priv causes a kernel oops/splat (as reported by the fix author) and can panic or hang the system, which is High availability impact."
