      "scenario": "AV:L - The vulnerable paths are exposed through local IIO sysfs attributes and the IIO character device for the MPU3050 sensor, not through a network protocol.\nAC:L - Although this is a probe/remove ordering race, a local attacker can hammer the published IIO interfaces while the device is being registered or torn down; no special heap layout or condition beyond the device being present is required for the vulnerable callbacks to be reached.\nPR:L - A basic local user can reach world-readable IIO sysfs attributes, and typical IIO device deployments expose these sensor interfaces to local users or services. No real init-namespace administrative capability is required for the read-side race.\nUI:N - Exploitation does not require a victim user to open a file or perform another action; the attacker directly accesses the local IIO interfaces.\nS:U - The issue corrupts or misuses kernel objects within the same kernel security authority. It does not cross a VM, IOMMU, or other separate security scope boundary.\nC:H - The old ordering can leave userspace-visible IIO attributes and file operations pointing at freed or partially initialized buffer/trigger state. This use-after-free class can be leveraged for kernel memory disclosure, so confidentiality impact is High.\nI:H - The dangling IIO buffer state includes function-pointer-bearing access structures and kernel object pointers reachable from callbacks. A use-after-free in this context is defensibly exploitable for control-flow hijack or arbitrary kernel memory modification.\nA:H - Even without full exploitation, racing these callbacks against probe or removal can dereference invalid or freed kernel objects and crash or hang the kernel."
