Security Notice for Linux Kernel – Risk Level: Medium

  • Risk Level: 2 (Medium)
  • CVSS Base Score: 6.5
  • CVSS Temporal Score: 6.0
  • Remote Attack: Yes

The Common Vulnerability Scoring System (CVSS) is used to assess the vulnerability of computer systems. The CVSS standard allows potential or actual security vulnerabilities to be compared based on various criteria, aiding in the prioritization of countermeasures. Vulnerability severity levels are categorized as “none,” “low,” “medium,” “high,” and “critical.” The Base Score evaluates the conditions for an attack (such as authentication, complexity, privileges, user interaction) and its consequences. The Temporal Score incorporates factors that can change over time. The current vulnerability is rated as “medium” with a CVSS Base Score of 6.5.

General Recommendations for Handling IT Vulnerabilities

Users of affected applications should ensure their software is up to date. Manufacturers are expected to address discovered vulnerabilities promptly by developing patches or workarounds. If new security updates are available, they should be installed promptly.
