CVE-2026-34761: Ella Core Panics Upon NGAP handover failure

MediumCVSS 6.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 26/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.32% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: ellanetworks core 1.8.0.

Low priority for now. Upgrade to ellanetworks core 1.8.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Ella Core is a 5G core designed for private networks. Prior to version 1.8.0, Ella Core panics when processing a NGAP handover failure message. An attacker able to cause a gNodeB to send NGAP handover failure messages to Ella Core can crash the process, causing service disruption for all connected subscribers. This issue has been patched in version 1.8.0.
