How do I fix CVE-2018-19320?

No fixed release is recorded for CVE-2018-19320 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.

How do I detect CVE-2018-19320 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-2018-19320 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is CVE-2018-19320 actively exploited in the wild?

Yes. There are 11 known exploit references for CVE-2018-19320, including 8 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2018-19320?

CVE-2018-19320 has an EPSS (Exploit Prediction Scoring System) score of 3.6%, placing it in the 89th 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.

Is CVE-2018-19320 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2018-19320 (GIGABYTE Multiple Products Unspecified Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2022-10-24. CISA required all US federal civilian agencies to remediate this vulnerability by 2022-11-14. The required action was: Apply updates per vendor instructions. This CVE has been used in known ransomware campaigns. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

When was CVE-2018-19320 published, and has it been updated?

CVE-2018-19320 was published on December 21, 2018 and was last updated on August 13, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
