CVE-2026-37232: An issue was discovered in OpenAirInterface5G 2.4.0 (nr-softmodem) in the E2SM-KPM RAN Function's PRB utilization metric

A vulnerability in OpenAirInterface5G 2.4.0 allows an attacker to crash a 5G base station by sending many subscription requests through an interface, which causes the system to divide by zero (attempting to divide a number by zero) when calculating radio resource usage metrics, knocking the 5G network offline for all connected devices.
