Security Advice for Linux Kernel – Risk: medium
Risk level: 3 (medium)
CVSS Base Score: 6,6
CVSS Temporal Score: 5,8
Remote Attack: No
The Common Vulnerability Scoring System (CVSS) is used to assess the severity of security vulnerabilities in computer systems. The CVSS standard makes it possible to compare potential or actual security gaps based on various metrics in order to create a priority list based on this for initiating 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. With the temporal score, framework conditions that change over time are included in the evaluation. The severity of the vulnerability discussed here is classified as “medium” according to the CVSS with a base score of 6.6.
