CVE-2019-11098
Insufficient input validation in MdeModulePkg in EDKII may allow an unauthenticated user to potentially enable escalation of privilege, denial of service and/or information disclosure via physical access.
Does this matter?
Lower severity and a low EPSS score (0.34%). Track it; it rarely justifies an emergency change on its own.
