"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/i915: mark requests for GuC virtual engines to avoid use-after-free\n\nReferences to i915_requests may be trapped by userspace inside a\nsync_file or dmabuf (dma-resv) and held indefinitely across different\nproceses. To counter-act the memory leaks, we try to not to keep\nreferences from the request past their completion.\nOn the other side on fence release we need to know if rq->engine\nis valid and points to hw engine (true for non-virtual requests).\nTo make it possible extra bit has been added to rq->execution_mask,\nfor marking virtual engines.\n\n(cherry picked from commit 280410677af763f3871b93e794a199cfcf6fb580)"

"value": "AV:L - The vulnerability is reached only through the i915 DRM device node (/dev/dri/renderD* or card node) via GEM context-create/submit ioctls and fence export; there is no network path.\nAC:L - The attacker controls both the freeing of the virtual engine (destroying the GEM context) and the release of the trapped fence, so the dangling-pointer dereference can be ordered deterministically without winning any uncontrollable race.\nPR:L - Creating parallel/virtual GuC contexts and submitting work requires only access to the DRM render node, available to any ordinary local user with GPU access; no CAP_SYS_ADMIN or real root is needed.\nUI:N - The entire sequence (context create, submit, fence trap, context destroy, fence release) is performed by the attacker's own process with no victim action required.\nS:U - The use-after-free corrupts kernel heap memory within the kernel's own security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The freed guc_virtual_engine object is read (engine->flags) after being reallocated, and the attacker can spray controlled contents into it, enabling disclosure of kernel memory contents.\nI:H - Beyond controlling freed-object contents, the power-of-2/single-sibling path performs a cmpxchg write into the freed engine's request_pool field, providing a UAF write primitive usable for heap corruption and control-flow influence.\nA:H - Dereferencing the dangling rq->engine on the fence-release path readily causes a kernel oops/panic, a reliable denial of service."
