Overview

CVE-2025-6297 is a high-severity vulnerability. It was published on July 1, 2025 and has a CVSS 3.1 base score of 8.2 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.2, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

It was discovered that dpkg-deb does not properly sanitize directory permissions when extracting a control member into a temporary directory, which is

documented as being a safe operation even on untrusted data. This may result in leaving temporary files behind on cleanup. Given automated and repeated execution of dpkg-deb commands on

adversarial .deb packages or with well compressible files, placed

inside a directory with permissions not allowing removal by a non-root

user, this can end up in a DoS scenario due to causing disk quota

exhaustion or disk full conditions.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
