Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Vector
Red Hat: CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:H
NVD: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
Red Hat CVSS v3 Score Explanation
The Attack Vector (AV) is Physical (P) because a maliciously crafted USB audio device is needed. The Confidentiality impact (C) is Low (L) because restricted information may appear in kernel log but the attacker has no control over this.
