Description

A flaw was found in the Linux kernel's DisplayPort Multi-Stream Transport (DP MST) subsystem.

A local user or an attacker with physical access to the display port can trigger this flaw during topology removal, leading to memory corruption and a Denial of Service (DoS) through a system crash.

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).
