Title
drm/nouveau: keep DMA buffers required for suspend/resume
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: keep DMA buffers required for suspend/resume Nouveau deallocates a few buffers post GPU init which are required for GPU suspend/resume to function correctly. This 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. This commit addresses that regression by moving the two buffers required for suspend and resume to be deallocated at driver unload instead of post init.

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\u0027s own process \\u2014 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\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed by the driver\u0027s own security scope.\\nC:H - The freed RMARGS/WPR-meta DMA pages remain mapped into GSP-RM\u0027s libos address space and hold the physical address of GSP-RM\u0027s 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.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"6190d4c08897d748dd25f0b78267a90aa1694e15\", \"lessThan\": \"be00e15b240ed71fc30c0576af7ab670c8271661\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"042b5f83841fbf7ce39474412db3b5e4765a7ea7\", \"lessThan\": \"f6ecfdad359a01c7fd8a3bcfde3ef0acdf107e6e\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"6.7.6\", \"lessThan\": \"6.7.9\", \"versionType\": \"semver\"}], \"programFiles\": [\"drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c\"], \"defaultStatus\": \"unaffected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/be00e15b240ed71fc30c0576af7ab670c8271661\"}, {\"url\": \"https://git.kernel.org/stable/c/f6ecfdad359a01c7fd8a3bcfde3ef0acdf107e6e\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"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.\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.7.9\", \"versionStartIncluding\": \"6.7.6\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-08-05T11:29:42.130Z\"}}}",
