Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Lock XArray when getting entries for the VM Similar to commit cac075706f29 ("drm/panthor: Fix race when converting group handle to group object") we need to use the XArray's internal locking when retrieving a vm pointer from there. v2: Removed part of the patch that was trying to protect fetching the heap pointer from XArray, as that operation is protected by the @pool->lock.

No network or remote path exists.\nAC:L - The attacker controls both sides of the race entirely \u2014 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 \u2014 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-\u003eunusable, 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-\u003eops-\u003evm_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 \u2014 a full denial of service."
