What is CVE-2026-32320?

Ella Core, a solution designed for private 5G networks, experiences a denial of service issue due to its handling of PathSwitchRequest messages. Specifically, versions prior to 1.5.1 can crash when processing requests that include UE Security Capabilities with zero-length NR encryption or integrity protection algorithm bitstrings. An attacker can exploit this vulnerability by sending crafted NGAP messages, resulting in significant service disruption for all subscribers connected to the network. This flaw has been addressed in version 1.5.1.
