"value": "AV:L - The vulnerable code is reached through local kernel interfaces for the Intel NPU/ivpu device, including debugfs log reads and recovery/coredump paths after local job submission. There is no network or adjacent-radio entry point.\nAC:L - No race or difficult timing is required once invalid firmware log indices are present; the log read/recovery path directly consumes them. A local attacker can repeatedly exercise the NPU and trigger log printing or recovery.\nPR:L - The relevant DRM accel ioctls do not require capabilities, and the debugfs fw_log file is created as readable when debugfs is accessible. This is reachable by a local low-privileged user with access to the NPU device/debug interface, not by an unauthenticated remote attacker.\nUI:N - Exploitation does not require a separate victim action. The attacker can invoke the local device/debugfs path directly.\nS:U - The impact is within the local kernel/device driver security authority. It does not cross a VM, IOMMU, or other separate security scope boundary.\nC:H - Unbounded firmware-controlled indices can make the driver read far beyond the firmware log BO and print kernel memory through the log/coredump output path. This is an out-of-bounds read that can disclose high-value kernel memory.\nI:N - The vulnerable path reads bytes and prints them; it does not write out of bounds or provide an evident memory modification primitive. The fix only clamps read offsets.\nA:H - Out-of-bounds reads from a vmapped buffer can fault while walking unmapped memory or consume excessive resources while printing. This can cause a kernel oops/panic or serious denial of service."
