Common questions
How do I fix CVE-2020-25672?
Published advisories record a fix for 107 affected products. The "How to fix" section on this page lists the fixed version and source advisory for each one, so apply the entry matching what you actually run.
Is CVE-2020-25672 being actively exploited?
Not that we know of. CVE-2020-25672 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 3.1% is the estimated probability that it will be exploited in the next 30 days. That is higher than 87% of all scored CVEs.
How severe is CVE-2020-25672?
CVE-2020-25672 has a CVSS v3 base score of 7.5, rated high. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.
What does CVE-2020-25672 affect?
Published advisories record a fix for linux (Debian), linux (Ubuntu), linux-aws (Ubuntu), linux-aws-5.4 (Ubuntu), and 103 more. Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.
