CVE-2024-24455Network attack vector

Cellular service interruption via invalid UE identifier

Published Nov 15, 2024 · Updated Aug 26, 2025

Invalid memory access in the MME of HPE Athonet Core 11.0 through 11.6 allows remote attackers to interrupt cellular service. The proprietary MME mishandles a UE Context Release message containing an invalid UE identifier, but public sources do not disclose the deeper programmatic cause. Unauthenticated access to the cellular signaling path and repeated crafted connections are required to crash the MME and sustain the network outage.
