How severe is CVE-2026-8779?

No CVSS score has been assigned to CVE-2026-8779 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-8779?

CVE-2026-8779 affects the following packages: github.com/omec-project/amf (Go). Ecosystems affected: Go.

How do I fix CVE-2026-8779?

Update github.com/omec-project/amf to 2.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-8779 is resolved across your whole dependency graph.

How do I detect CVE-2026-8779 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/omec-project/amf. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2026-8779 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.

How does O3 Security protect against CVE-2026-8779?

O3 pinpoints whether CVE-2026-8779 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2026-8779 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-8779 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-2026-8779?

CVE-2026-8779 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 23th 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-2026-8779?

CVE-2026-8779 is classified as Buffer Overflow (CWE-119). This weakness type 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-2026-8779 published, and has it been updated?

CVE-2026-8779 was published on May 18, 2026 and was last updated on August 12, 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

A vulnerability was determined in omec-project amf up to 2.1.3-dev. Impacted is the function NGSetupRequest of the file ngap/handler.go. Executing a manipulation of the argument InformationElement can lead to memory corruption. The attack can be launched remotely. The exploit has been publicly disclosed and may be utilized. Upgrading to version 2.2.0 is recommended to address this issue. The affected component should be upgraded. The same pull request fixes multiple security issues.
