amdgpu SDMA v4 trap interrupt handler, reached only through GPU activity driven from the local system via a DRM render node (/dev/dri/renderD*) or device-generated interrupts; there is no network-facing path to it.\nAC:H - The broken error path only executes when the interrupt vector carries an SDMA client_id that sdma_v4_0_irq_id_to_seq() does not map, yet amdgpu_irq_dispatch() only routes to this handler for client IDs explicitly registered by sw_init(), all of which map to valid seq 0-7 — so triggering it depends on malformed hardware/firmware interrupt data entirely outside the attacker's influence.\nPR:L - Exercising sdma_v4_0_process_trap_irq() requires only the ability to submit SDMA work through an unprivileged DRM render node, which is available to ordinary desktop/container users in the render group with no elevated capability.\nUI:N - The handler runs from interrupt context on GPU-generated SDMA traps that the attacker's own submissions produce; no action by any other user is needed.\nS:U - The out-of-bounds access stays within the kernel's own memory and security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The unsigned conversion yields index 0xFFFFFFEA, and amdgpu_fence_process() reads fence_drv state, the adev back-pointer, and a dma_fence pointer through that far out-of-bounds address, exposing arbitrary kernel memory contents to fence-signalling logic.\nI:H - The wild pointer is not read-only — amdgpu_fence_process() performs atomic_cmpxchg on drv->last_seq, RCU_INIT_POINTER stores into drv->fences[], timer_delete() on an unvalidated timer_list, and dma_fence_signal()/dma_fence_put() through garbage ->ops function pointers, giving out-of-bounds writes and indirect-call hijack potential.\nA:H - Dereferencing an address roughly 11 TB past the amdgpu_device allocation faults in interrupt context, producing a kernel oops/panic and loss of the GPU and typically the whole system." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [
