CVE-2022-40504Network attack vector

Transient service interruption via modem assertion

Published May 2, 2023 · Updated Aug 3, 2024

A reachable assertion in Qualcomm Snapdragon modem firmware allows remote attackers to interrupt cellular service via a network message. The modem reaches an assertion while processing a downlink data indication received from the cellular network, causing a transient denial of service instead of safely handling the indication. Exploitation requires network delivery to an affected modem but requires no authentication, local access, or user interaction.
