No network or remote path exists.\nAC:L - The attacker controls both sides of the race entirely — one thread loops on VM_DESTROY while another loops on VM_GET_STATE/VM_BIND/TILER_HEAP_CREATE/GROUP_CREATE with the same handle on the same drm_file — and can retry indefinitely at no cost while arranging the VM to hold exactly one reference so the destroy frees it.\nPR:L - All involved ioctls are DRM_RENDER_ALLOW, so any local user or sandboxed application with render-node access (standard for Android apps, the Chrome GPU process, and desktop sessions on Mali CSF hardware) can trigger it. No capabilities or root are required.\nUI:N - The attacking process performs both racing ioctls itself; no victim action, mount, or file open by another user is needed.\nS:U - The corruption is confined to kernel memory within the same security authority; there is no VM, IOMMU, or hypervisor boundary crossed.\nC:H - The use-after-free lets the attacker reclaim the freed panthor_vm slot with sprayed data and have the kernel read it back (vm->unusable, heaps.pool, gpuvm ops), and a group holding the freed VM keeps using its io-pgtable state, enabling disclosure of kernel memory.\nI:H - The racing kref_get performs a refcount_inc write into freed, attacker-reclaimable heap memory, and drm_gpuvm_free() later dispatches through gpuvm->ops->vm_free read from that same reclaimed object, giving write and control-flow-hijack primitives; the extra put also produces a double free.\nA:H - Even unexploited, the UAF and the resulting double free reliably cause refcount warnings, mutex operations on freed memory, and kernel oops/panic, plus dangling GPU page tables — a full denial of service." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/gpu/drm/panthor/panthor_mmu.c" ], "versions": [ { "version": "647810ec247641eb5aec8caef818919a4518a0b1", "lessThan": "3342f066a8e1020a6f7d1fbd6b23bfdeda473eb5", "status": "affected", "versionType": "git" }, { "version": "647810ec247641eb5aec8caef818919a4518a0b1", "lessThan": "444fa5b100e5c90550d6bccfe4476efb0391b3ca", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/gpu/drm/panthor/panthor_mmu.c" ], "versions": [ { "version": "6.10", "status": "affected" }, { "version": "0", "lessThan": "6.10", "status": "unaffected", "versionType": "semver" }, { "version": "6.11.8", "lessThanOrEqual": "6.11.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.10", "versionEndExcluding": "6.11.8" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.10", "versionEndExcluding": "6.12" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/3342f066a8e1020a6f7d1fbd6b23bfdeda473eb5" }, { "url": "https://git.kernel.org/stable/c/444fa5b100e5c90550d6bccfe4476efb0391b3ca" }, { "url": "https://project-zero.issues.chromium.org/issues/377500597" } ], "title": "drm/panthor: Lock XArray when getting entries for the VM", "x_generator": { "engine": "bippy-1.2.0" } } } }
