Answer in brief
CVE-2019-1388 records a High severity vulnerability in CVE Program Container. The current sources mark it as known exploited. The current feed maps Microsoft/Windows (generic), Microsoft/Windows 10 Version 1903 for 32-bit Systems (generic), Microsoft/Windows 10 Version 1903 for ARM64-based Systems (generic), Microsoft/Windows 10 Version 1903 for x64-based Systems (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. Known-exploitation status makes exposure review time-sensitive. Treat this as a source-backed prioritization signal, not a statement about your environment.
