No CVSS score has been assigned to GHSA-2hhg-8xx6-v73w yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-2hhg-8xx6-v73w?

Affected package information for GHSA-2hhg-8xx6-v73w is not yet fully mapped. Check the official advisory links for details.

How do I fix GHSA-2hhg-8xx6-v73w?

Upgrade the affected component to the fixed release for GHSA-2hhg-8xx6-v73w, or apply your distribution's backported patch — distro builds are often patched at an older version number, so check your vendor's advisory rather than the upstream version alone.

How do I detect GHSA-2hhg-8xx6-v73w in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

How do I mitigate GHSA-2hhg-8xx6-v73w if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Is GHSA-2hhg-8xx6-v73w actively exploited in the wild?

No public exploit code has been indexed for GHSA-2hhg-8xx6-v73w yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-2hhg-8xx6-v73w?

GHSA-2hhg-8xx6-v73w has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 34th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-2hhg-8xx6-v73w?

GHSA-2hhg-8xx6-v73w is classified as CWE-415 (CWE-415). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-2hhg-8xx6-v73w published, and has it been updated?

GHSA-2hhg-8xx6-v73w was published on October 12, 2026 and was last updated on October 29, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

FreeRDP before 3.32.0 contains a double-free vulnerability in nsc_context_initialize_encode() that leaves dangling plane pointers after a partial buffer growth failure. Attackers using a crafted RDP client can negotiate NSCodec with a large desktop geometry to trigger allocation failure, crashing the server during context teardown.
