CVE-2019-18913
A potential security vulnerability with pre-boot DMA may allow unauthorized UEFI code execution using open-case attacks.
Does this matter?
Lower severity and a low EPSS score (0.60%). Track it; it rarely justifies an emergency change on its own.
Description
A potential security vulnerability with pre-boot DMA may allow unauthorized UEFI code execution using open-case attacks.

This affects HP Intel-based Business PCs that support Microsoft Windows 10 Kernel DMA protection. Affected versions depend on platform (prior to 01.04.02; or prior to 02.04.01; or prior to 02.04.02).
