CVSS v3.1

Official Description

Incorrect parameter validation in the synaTee component of Synaptics WBF drivers using an SGX enclave (all versions prior to 2019-11-15) allows a local user to execute arbitrary code in the enclave (that can compromise confidentiality of enclave data) via APIs that accept invalid pointers.

Technical Analysis

CVE-2019-18619 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

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 7.8.
