"value": "AV:L - The vulnerable code is in amd_mp2_pci_probe for the onboard AMD Sensor Fusion Hub PCI device and is reached only via local driver probe/bind, not via network packets or a physically attached hotplug device.\nAC:L - An attacker who can apply memory pressure can make mid-probe allocations fail after DMA buffers are already allocated, reliably driving the broken cleanup path; no race or non-attacker-controlled hardware state is required.\nPR:L - Exploitation is assessed from a local unprivileged context on a system with the amd_sfh driver present; when privilege gating of PCI reprobe is ambiguous, the higher-severity Low value is required.\nUI:N - No separate victim action such as mounting a filesystem or opening a malicious file is required once probe runs under the attacker-influenced failure conditions.\nS:U - Impact remains within the kernel's own security authority; this is a host kernel memory-safety/DoS issue, not a VM escape or other cross-boundary impact.\nC:H - On probe failure after partial client init, amd_mp2_pci_remove double-frees DMA coherent allocations whose pointers were not cleared, yielding heap corruption that can be leveraged for arbitrary read primitives.\nI:H - The same double-free heap corruption provides a write/control-flow primitive surface consistent with treating exploitable memory corruption as High integrity impact.\nA:H - Both the mp2_ops NULL dereference on failed action registration and the double-free cleanup path cause kernel oops/panic and loss of system availability."
