Title
amdgpu: validate offset_in_bo of drm_amdgpu_gem_va
Summary
In the Linux kernel, the following vulnerability has been resolved: amdgpu: validate offset_in_bo of drm_amdgpu_gem_va This is motivated by OOB access in amdgpu_vm_update_range when offset_in_bo+map_size overflows. v2: keep the validations in amdgpu_vm_bo_map v3: add the validations to amdgpu_vm_bo_map/amdgpu_vm_bo_replace_map rather than to amdgpu_gem_va_ioctl
Severity

There is no network-facing path to `amdgpu_vm_bo_map()`.\nAC:L - A single ioctl with an attacker-chosen page-aligned `offset_in_bo` near 2^64 deterministically wraps the `offset + size` bounds check; there is no race, no timing window, and no dependence on memory layout the attacker cannot influence. The OOB index is fully attacker-controlled, so the target of the wild access can be aimed rather than guessed.\nPR:L - The ioctl is registered `DRM_AUTH|DRM_RENDER_ALLOW`, so any unprivileged local user with access to the render node can invoke it \u2014 this includes members of the render/video group, any user with a logind graphical session, containers with GPU passthrough, and sandboxed processes such as browser GPU processes. No root or capability is required.\nUI:N - The attacker performs GEM object creation and the malicious `AMDGPU_VA_OP_MAP`/`AMDGPU_VA_OP_REPLACE` ioctl entirely on its own; no victim action or cooperation is needed.\nS:U - The vulnerable amdgpu driver code and the corrupted kernel memory are within the same security authority (the host kernel). This is standard local kernel compromise rather than a VM or IOMMU boundary escape.\nC:H - The overflowed offset produces an OOB read `pages_addr[cursor.start \u003e\u003e PAGE_SHIFT]` at an attacker-chosen index spanning up to 2^55 bytes past the DMA-address array, and the value read becomes the physical address in a GPU page table entry, letting the attacker\u0027s GPU context read arbitrary physical memory. The TT node-walk path additionally performs unbounded OOB reads of kernel heap data.\nI:H - Because the OOB-read value is installed as a GPU PTE physical address, the attacker\u0027s own GPU commands gain DMA write access to arbitrary physical memory, giving a full arbitrary-write primitive suitable for kernel code/credential modification. Attacker-controlled page table entries also corrupt the VM state itself.\nA:H - The same input reliably produces kernel crashes \u2014 wild pointer dereference in the `node++` mm_nodes walk, a reachable `BUG_ON(start + size \u003e res-\u003esize)`, and an effectively unbounded VRAM block-walk loop executed while holding `vm-\u003eeviction_lock` with BOs reserved, causing a soft lockup/hang. Any of these panics or wedges the GPU and the system."
