How severe is CVE-2026-97865?

No CVSS score has been assigned to CVE-2026-97865 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-97865?

Affected package information for CVE-2026-97865 is not yet fully mapped. Check the official advisory links for details.

How do I fix CVE-2026-97865?

Upgrade the affected component to the fixed release for CVE-2026-97865, 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 CVE-2026-97865 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 CVE-2026-97865 if there is no patch (or I can't update yet)?

Do not deserialise data from untrusted sources: where the format allows it, restrict deserialisation to an explicit allowlist of expected types, and prefer a data-only format (JSON, Protobuf) over one that can reconstruct arbitrary objects until you can upgrade.

Is CVE-2026-97865 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-97865 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 CVE-2026-97865?

CVE-2026-97865 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 32th 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 CVE-2026-97865?

CVE-2026-97865 is classified as Improper Input Validation (CWE-20), Deserialization of Untrusted Data (CWE-502). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2026-97865 published, and has it been updated?

CVE-2026-97865 was published on September 25, 2026 and was last updated on September 30, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
