Security Advice for Linux Kernel – Risk: medium
Risk level: 3 (medium)
CVSS Base Score: 7,8
CVSS Temporal Score: 6,8
Remote Attack: No
The Common Vulnerability Scoring System (CVSS) is used to assess the severity of vulnerabilities in computer systems. The CVSS standard makes it possible to compare potential or actual security vulnerabilities based on various criteria in order to better prioritize countermeasures. The attributes “none”, “low”, “medium”, “high” and “critical” are used for the severity of a vulnerability. The base score assesses the prerequisites for an attack (including authentication, complexity, privileges, user interaction) and its consequences. The Temporal Score also takes into account changes over time with regard to the risk situation. The risk of the current vulnerability is classified as “medium” according to the CVSS with a base score of 7.8.
