Frequently Asked Questions
Who can exploit this issue?
The CVSS vector indicates that exploitation requires local access and low privileges. It does not indicate a network-accessible attack path or user interaction requirement.
What is the potential impact of successful exploitation?
The listed severity vector rates confidentiality, integrity, and availability impacts as high. A successful exploit could therefore affect data secrecy, system integrity, and system availability.
Which Ubuntu kernel variants are listed as affected?
The listed software includes ubuntu/linux, ubuntu/linux-fips, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, ubuntu/linux-gcp-fips, and ubuntu/linux-realtime.
