However, if driver load fails, this protection is\ninsufficient because drm_dev_unplug() is never called.\n\nAdditionally, devm release functions cannot guarantee that all BOs with\nGGTT mappings are destroyed before the GGTT MMIO region is removed, as\nsome BOs may be freed asynchronously by worker threads.\n\nTo address this, introduce an open-coded flag, protected by the GGTT\nlock, that guards GGTT MMIO access. The flag is cleared during the\ndev_fini_ggtt devm release function to ensure MMIO access is disabled\nonce teardown begins.\n\n(cherry picked from commit 4f3a998a173b4325c2efd90bdadc6ccd3ad9a431)"

It shouldn\u0027t be invalid since this is a re-insertion, so must have\nworked before. Leaving the likely culprit as something already placed\nwhere we want to insert the vma.\n\nFollowing from that, for the case where we do something like a rebind in\nthe middle of a vma, and one or both mapped ends are already compatible,\nwe skip doing the rebind of those vma and set next/prev to NULL. As well\nas then adjust the original unmap va range, to avoid unmapping the ends.\nHowever, if we trigger the unwind path, we end up with three va, with\nthe two ends never being removed and the original va range in the middle\nstill being the shrunken size.\n\nIf this occurs, one failure mode is when another unwind op needs to\ninteract with that range, which can happen with a vector of binds. For\nexample, if we need to re-insert something in place of the original va.\nIn this case the va is still the shrunken version, so when removing it\nand then doing a re-insert it can overlap with the ends, which were\nnever removed, triggering a warning like above, plus leaving the vm in a\nbad state.\n\nWith that, we need two things here:\n\n 1) Stop nuking the prev/next tracking for the skip cases. Instead\n    relying on checking for skip prev/next, where needed. That way on the\n    unwind path, we now correctly remove both ends.\n\n 2) Undo the unmap va shrinkage, on the unwind path. With the two ends\n    now removed the unmap va should expand back to the original size again,\n    before re-insertion.\n\nv2:\n  - Update the explanation in the commit message, based on an actual IGT of\n    triggering this issue, rather than conjecture.\n  - Also undo the unmap shrinkage, for the skip case. With the two ends\n    now removed, the original unmap va range should expand back to the\n    original range.\nv3:\n  - Track the old start/range separately. vma_size/start() uses the va\n    info directly.\n\n(cherry picked from commit aec6969f75afbf4e01fd5fb5850ed3e9c27043ac)"

This fence is used to wait for job\ncompletion.\n\nCurrently, the code drops the fence reference using dma_fence_put()\nbefore calling dma_fence_wait().\n\nIf dma_fence_put() releases the last reference, the fence may be\nfreed before dma_fence_wait() is called. This can lead to a\nuse-after-free.\n\nFix this by waiting on the fence first and releasing the reference\nonly after dma_fence_wait() completes.\n\nFixes the below:\ndrivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.c:697 amdgpu_amdkfd_submit_ib() warn: passing freed memory \u0027f\u0027 (line 696)\n\n(cherry picked from commit 8b9e5259adc385b61a6590a13b82ae0ac2bd3482)"

When uncertain, the lower-complexity option is appropriate.\nPR:L - The path requires local access to the KFD/AMDGPU device interfaces and a render/DRM VM FD, but no kernel administrative capability is checked by the relevant KFD queue ioctls. This is ordinary low-privileged local GPU access rather than real root.\nUI:N - After obtaining local device access, the attacker can issue the ioctl sequence themselves. No separate victim action is required.\nS:U - The impact is within the same kernel security authority: corrupting or crashing kernel/driver state from a local kernel attack surface. It does not cross a VM, IOMMU, or comparable security boundary.\nC:H - The bug is a use-after-free of a `dma_fence`/AMDGPU fence object used by `dma_fence_wait()`. Per kernel scoring guidance, UAF memory corruption can be leveraged for high confidentiality impact.\nI:H - The same UAF exposes kernel object lifetime corruption in a wait path using function pointers, locks, callbacks, and list state. Per guidance, UAF memory corruption is scored as high integrity impact.\nA:H - Even without full exploitation, using a freed fence in `dma_fence_wait()` can cause kernel warnings, crashes, hangs, or panics. A kernel UAF therefore has high availability impact."

No network or physical-device packet path reaches this code.\nAC:L - The race is between attacker-controlled processes sharing the same drm_file after fork and issuing concurrent VM-acquire operations. Because the attacker controls both sides of the race, this is low complexity.\nPR:L - An unprivileged local user with access to /dev/kfd and the amdgpu render node can issue the relevant ioctls; no real root or init-namespace capability check is required. This is basic local user access rather than administrative privilege.\nUI:N - Exploitation does not require a victim user action after the attacker has local execution and device access. The attacker can open the device files, fork, and invoke the ioctls directly.\nS:U - The bug corrupts kernel driver state within the same kernel security authority. It is a standard local kernel memory-corruption/privilege-escalation scenario, not a VM escape or other scope change.\nC:H - The non-atomic VM ownership assignment can leave stale amdkfd_process_info references and cause a kernel use-after-free. Following kernel UAF scoring guidance, this can be leveraged for high-impact information disclosure.\nI:H - The freed process_info object contains list, mutex, fence, and process state used later by KFD/GPUVM paths, making this kernel memory corruption. A defensible worst case is arbitrary kernel memory modification or control-flow influence.\nA:H - Even without full exploitation, the UAF and associated list/lifetime corruption can crash or hang the kernel. Kernel oops/panic-level denial of service is high availability impact."

Because the attacker controls both sides of the race, this is low complexity.\nPR:L - NETLINK_SOCK_DIAG read requests are accepted from non-root users, and the SCTP diag path only uses CAP_NET_ADMIN to gate extra reporting details.

The attacker can create SCTP sockets, race teardown, and issue the diagnostic query directly.\nS:U - The issue affects kernel SCTP diagnostic handling within the same host kernel security authority. It does not cross a VM, IOMMU, or other separate security scope boundary.\nC:H - The stale association can cause an out-of-bounds read from unrelated association memory and return data through the netlink diagnostic response. Following the higher-severity rule for kernel OOB reads, this is treated as high confidentiality impact.\nI:N - The investigated path formats and returns stale association state but does not write through attacker-controlled stale pointers.
