"value": "AV:L - The vulnerable code is reached only through local PCI driver probe of the Intel THC QuickI2C controller, consuming ACPI `_DSD` data from the local platform firmware namespace; there is no network or adjacent-network path to it.\nAC:L - The overflow is fully deterministic — every probe on affected hardware copies a firmware-returned buffer that is one byte larger than the destination stack struct, with no race, no memory-layout dependency, and no conditional configuration required.\nPR:N - The vulnerable memcpy executes unconditionally during automatic async device probe at boot, before any user authenticates; no capability, credential, or privileged operation is checked anywhere on the path from PCI enumeration to the overflow.\nUI:N - Probe is triggered by PCI device enumeration on the async probe workqueue with no user action whatsoever — no file to open, no device to attach, no mount to perform.\nS:U - The corruption is confined to the kernel stack within the same security authority; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - An out-of-bounds write on the kernel stack adjacent to other frame locals, saved registers, and the return address is leveragable for control-flow manipulation and therefore arbitrary kernel memory disclosure, and the copy length is entirely unvalidated so the overwrite is not inherently bounded.\nI:H - This is a stack out-of-bounds write whose size comes unchecked from the ACPI buffer length, giving a write primitive past the destination object into the caller's frame — including canary and saved return address — which is the classic path to control-flow hijack.\nA:H - The bug is a confirmed KASAN stack-out-of-bounds that crashed the kernel on affected hardware, and stack corruption reliably produces a panic (stack-protector abort or corrupted return), rendering the machine unbootable at probe time."
