What is CVE-2025-6297?

DPKG has a vulnerability related to improper handling of directory permissions during the extraction of control members into temporary directories. This flaw allows the execution of dpkg-deb commands on adversarial .deb packages, which may lead to lingering temporary files and conditions that can result in a denial of service. Specifically, if a directory is set with permissions that prevent removal by non-root users, repeated automated executions can exhaust disk quotas, leading to potential full disk scenarios.
