CVE-2022-33250Network attack vector

Transient modem interruption via invalid handover container

Published Mar 7, 2023 · Updated Aug 3, 2024

Reachable assertion in Qualcomm Snapdragon modem firmware allows remote attackers to interrupt service through crafted handover traffic. The modem repeatedly processes an invalid message container during an NR-to-LTE handover and reaches an assertion. Exploitation requires network delivery of the malformed container multiple times, and the documented consequence is a transient service interruption.
