# CVE-2025-6297: dpkg-deb: Fix cleanup for control member with restricted directories > Attackers can cause disk exhaustion and denial of service by exploiting improper cleanup of temporary files during dpkg-deb extraction of malicious packages. - **Severity:** High 8.2 (`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 1 Jul 2025 - **Updated:** 8 Jul 2026 - **Also known as:** AZL-64641, CLSA-2025-1760024944, CLSA-2025-1764321086, DEBIAN-CVE-2025-6297, ECHO-9dc0-d8d0-3783, GHSA-w56q-6jw5-h5xf, MGASA-2025-0204, SUSE-SU-2025:02734-1, SUSE-SU-2025:20562-1, SUSE-SU-2025:20670-1, UBUNTU-CVE-2025-6297, USN-7768-1, openSUSE-SU-2025:15314-1 ## What is CVE-2025-6297? CVE-2025-6297 is a high-severity denial of service vulnerability in Debian dpkg, published on 1 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official 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.

What it is: CVE-2025-6297 is a high-severity denial of service vulnerability in Debian dpkg, published on 1 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim. Exploitation: There is no known exploitation of CVE-2025-6297 in the wild and no public exploit code. Affected product: Debian dpkg. No package-level version data is available, so check the vendor advisory linked from the reference page. Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
