CVE-2025-26265Public exploitNetwork attack vector

Service crash via crafted context-modification response

Published Mar 27, 2025 · Updated Mar 28, 2025

A segmentation fault in openairinterface5g 2.1.0 allows attackers to crash the service via a crafted UE Context Modification response. Public records do not identify the affected function or the invalid buffer operation that triggers the segmentation fault. The response must reach the network-exposed processing path and requires interaction with a UE-context modification exchange; the reported consequence is service interruption only.
