"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/nouveau: keep DMA buffers required for suspend/resume\n\nNouveau deallocates a few buffers post GPU init which are required for GPU suspend/resume to function correctly.\nThis is likely not as big an issue on systems where the NVGPU is the only GPU, but on multi-GPU set ups it leads to a regression where the kernel module errors and results in a system-wide rendering freeze.\n\nThis commit addresses that regression by moving the two buffers required for suspend and resume to be deallocated at driver unload instead of post init."

"value": "AV:L - The vulnerable path is the nouveau GPU suspend/resume handler, reached through local DRM device-node usage and PCI runtime power management; no network or physical access is involved.\nAC:L - The condition is deterministic — `gsp->wpr_meta.data` and `gsp->rmargs.data` are unconditionally NULLed at postinit, so the very first suspend after driver load faults with no race and no memory-layout dependency.\nPR:L - An unprivileged local user with access to `/dev/dri/renderD*` (the default for a desktop session) can force a `pm_runtime_get_sync`/`put_autosuspend` cycle by opening and closing the render node, triggering runtime suspend within the 5s autosuspend delay; on hybrid-graphics systems it also fires from mere idling.\nUI:N - Nouveau enables runtime PM by default on Optimus/multi-GPU systems, so autosuspend fires automatically after idle and can be induced by the attacker's own process — no victim action such as closing a lid or invoking `systemctl suspend` is needed.\nS:U - The fault and its consequences remain within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed by the driver's own security scope.\nC:H - The freed RMARGS/WPR-meta DMA pages remain mapped into GSP-RM's libos address space and hold the physical address of GSP-RM's shared message queues, so the GPU continues reading memory the kernel has released and reallocated, exposing arbitrary reclaimed kernel data to the device.\nI:H - Premature `dma_free_coherent()` of buffers whose bus addresses are still programmed into the GPU is a device-side use-after-free; queue physical addresses sprayed into the reclaimed page are consumed by GSP-RM as DMA targets, yielding a write primitive into arbitrary kernel memory.\nA:H - A guaranteed NULL pointer dereference at NULL+0xa8 in `r535_gsp_fini()` oopses inside the PM path with device locks held, producing the reported system-wide rendering freeze and an unrecoverable suspend/resume failure."
