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"}}}}
