- The bug is reached through the RADEON_GEM_VA ioctl on a local DRM device node (/dev/dri/renderD128 or card0), raced against DRM_IOCTL_GEM_CLOSE on the same fd. No network or physical access is involved.\nAC:L - The attacker owns both sides of the race — one thread issues GEM_VA MAP, another issues GEM_CLOSE — and radeon_vm_bo_set_addr() unreserves the BO and then performs long page-table allocation and GPU IB submission before radeon_gem_va_update_vm() runs, leaving a very wide, reliably winnable window.\nPR:L - RADEON_GEM_VA and GEM_CLOSE are both DRM_RENDER_ALLOW and drm_ioctl bypasses DRM_AUTH for render clients, so any local unprivileged user (or containerized/sandboxed process handed a render node) can reach the path with no capabilities.\nUI:N - The attacker drives the entire sequence from its own two threads on a self-opened DRM fd; no victim action or cooperation is needed.\nS:U - The corruption stays within the kernel's own security authority — a standard local kernel memory-safety bug, not a VM, IOMMU, or hypervisor boundary crossing.\nC:H - This is a use-after-free of the radeon_bo_va slab object; with the freed slot refilled, bo_va->bo->tbo.resource supplies mem->start, which is programmed as a raw physical address into GPU page tables, giving GPU-side reads of arbitrary physical memory.\nI:H - The freed object is written through by radeon_vm_bo_update() via list_del()/list_add() on bo_va->vm_status and bo_va->flags, and bo_va->vm is dereferenced for mutex_unlock(), yielding unlink/write primitives plus attacker-influenced GPU page-table entries.\nA:H - In the common case the freed bo_va still holds the NULL written by radeon_bo_unref(), so bo_va->bo->tbo.resource is a NULL-pointer dereference producing an immediate kernel oops, and any unlucky slab reuse panics on corrupted list pointers."}]}],"providerMetadata":{"shortName":"Linux","orgId":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","dateUpdated":"2026-08-05T11:35:05.718Z"},"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"5.10.234"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"5.15.164"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.1.101"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.6.42"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.9.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.10"}]}]}],"x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/a2b201f83971df03c8e81a480b2f2846ae8ce1a3","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/a9100f17428cb733c4f6fbb132d98bed76318342","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/f13c96e0e325a057c03f8a47734adb360e112efe","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/8a500b3a5f0a58c6f99039091fbd715f64f2f8af","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/6fb15dcbcf4f212930350eaee174bb60ed40a536","tags":["x_transferred"]},{"url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"},{"url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}],"providerMetadata":{"shortName":"CVE","orgId":"af854a3a-2127-422b-91ae-364da2661108","dateUpdated":"2025-11-03T22:00:08.758Z"}},{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-41060","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-09-10T16:22:11.951326Z"}}}],"providerMetadata":{"shortName":"CISA-ADP","orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","dateUpdated":"2024-09-11T17:34:01.439Z"}}]}}}
