Frequently Asked Questions

1

What level of access does an attacker need to exploit this issue?

The CVSS vector indicates local attack access, with no privileges or user interaction required and low attack complexity. This means the issue is relevant where an attacker can execute code or otherwise act locally on a system.

2

Which installed components are in scope for this update?

The advisory lists rocky-linux/libblkid, rocky-linux/libfdisk, and rocky-linux/libmount, including their debuginfo and development packages. Systems with these Rocky Linux packages installed should review the applicable security update.

3

What is the potential security impact?

The issue is an integer overflow in the DOS partition parser that can compromise partition metadata. The supplied CVSS vector rates confidentiality impact as low and integrity and availability impact as high.
