Technical Analysis

CVE-2023-47855 requires local access, meaning attackers must already have a foothold on the target system.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 6.7.
