## What is CVE-2025-62599?

CVE-2025-62599 is a high-severity vulnerability in Debian Debian Linux, published on 3 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

eprosima Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group). Prior to 2.6.11, 2.14.6, 3.2.4, 3.3.1, and 3.4.1, when the security mode is enabled, modifying the DATA Submessage within an SPDP packet sent by a publisher causes an Out-Of-Memory (OOM) condition, resulting in remote termination of Fast-DDS.
If the fields of PID_IDENTITY_TOKEN or PID_PERMISSION_TOKEN in the DATA Submessage — specifically by tampering with the length field in readPropertySeq — are modified, an integer overflow occurs, leading to an OOM during the resize operation. This vulnerability is fixed in 2.6.11, 2.14.6, 3.2.4, 3.3.1, and 3.4.1.

Weakness: CWE-789 (Memory Allocation with Excessive Size Value), CWE-190 (Integer Overflow or Wraparound)

Check this codebase for CVE-2025-62599 and fix it if it is affected.

What it is: CVE-2025-62599 is a high-severity vulnerability in Debian Debian Linux, published on 3 Feb 2026. 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-2025-62599 in the wild and no public exploit code.

Affected product: Debian Debian Linux. 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.
