CVE-2024-24452Network attack vector

Cellular service interruption via malformed E-RAB messages

Published Nov 15, 2024 · Updated Mar 31, 2025

Invalid memory access in Athonet vEPC MME 11.4.0 allows remote attackers to interrupt cellular service via crafted S1AP messages. The E-RAB Release Indication handler performs an invalid memory access while processing a crafted ProtocolIE_ID field. Repeated unauthenticated connections to the S1-MME control-plane interface can deny subscriber connectivity, but no code execution is reported.
