CVE-2026-10115: Open5GS Shared NF-profile nnrf-handler.c denial of service

A vulnerability was identified in Open5GS up to 2.7.7. This affects an unknown part in the library lib/sbi/nnrf-handler.c of the component Shared NF-profile Parser. Such manipulation leads to denial of service. The attack can be launched remotely. The exploit is publicly available and might be used. It is advisable to implement a patch to correct this issue.

Security readout for executives and security teams

Plain-English summary

CVE-2026-10115 is a remotely reachable denial-of-service issue in Open5GS versions 2.7.0 through 2.7.7. It affects parsing of shared NF-profile data. A successful attack could disrupt affected 5G core network functions. Public sources say exploit material is available, but KEV does not list active exploitation.

Executive priority

Treat as a near-term resilience issue for Open5GS-based mobile core environments. Prioritize systems supporting production network services or reachable across shared infrastructure. Business urgency is moderate unless affected interfaces are broadly exposed or availability requirements are strict.

Technical view

The issue is reported in Open5GS lib/sbi/nnrf-handler.c, in the Shared NF-profile Parser. The CVSS 4.0 vector is 5.3, network reachable, low attack complexity, low privileges required, no user interaction, and low availability impact. CWE-404 is assigned. A GitHub pull request is referenced as a patch source, but the bundle does not name a fixed release.

Likely exposure

Organizations running Open5GS 2.7.0 through 2.7.7 are potentially exposed, especially where NRF-related service interfaces are reachable by untrusted or loosely trusted network actors. Exposure depends on deployment architecture, access controls, and whether affected components are enabled.

Exploitation context

The vulnerability can be launched remotely and public exploit material is reported. The CVSS vector requires low privileges, so this is not described as unauthenticated in the provided data. There is no KEV listing and no cited evidence of active exploitation in the supplied sources.

Researcher notes

The source data identifies the affected file and parser but not the exact input condition. Avoid assuming affected network functions beyond what Open5GS issue references state. The patch reference is a GitHub pull request, while a fixed release is not named in the bundle.

Mitigation direction

  • Identify Open5GS deployments and versions, prioritizing 2.7.0 through 2.7.7.
  • Review Open5GS pull request 4527 and vendor project guidance for the patch path.
  • Restrict access to Open5GS service interfaces to trusted network segments.
  • Monitor Open5GS processes for crashes or repeated availability failures.
  • Upgrade when the Open5GS project publishes a fixed release or endorsed patch.

Validation and detection

  • Confirm deployed Open5GS version against the affected 2.7.0 through 2.7.7 range.
  • Check whether components using shared NF-profile parsing are enabled.
  • Review network controls limiting access to NRF and related SBI interfaces.
  • Verify whether PR 4527 or later vendor guidance is applied.
  • Look for service restarts, crashes, or denial-of-service symptoms in Open5GS logs.
