CVE-2023-43529Network attack vector

Service interruption via malformed IKEv2 fragment

Published May 6, 2024 · Updated Aug 2, 2024

Reachable assertion in Qualcomm Snapdragon Data Modem firmware allows remote attackers to interrupt service via a malformed IKEv2 fragment. The IKEv2 Informational-request path reaches an assertion while processing a malformed fragment packet. No authentication or user interaction is required, and the resulting denial of service is transient rather than persistent.
