CVE-2020-8322
A potential vulnerability in the SMI callback function used in the Legacy USB driver in some Lenovo Notebook and ThinkStation models may allow arbitrary code execution.
Does this matter?
Lower severity and a low EPSS score (0.33%). Track it; it rarely justifies an emergency change on its own.
