Technical Analysis
CVE-2020-16235 requires local access, meaning attackers must already have a foothold on the target system.

A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 6.5.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
