CVE-2022-23937Network attack vector

Availability loss via crafted IKE packet

Published Mar 29, 2022 · Updated Aug 3, 2024

Out-of-bounds read in Wind River VxWorks 6.9 and 7 allows remote attackers to cause availability loss via a crafted IKE packet. During an IKE initial exchange, processing the packet reads beyond the intended memory boundary; public records do not identify the malformed field or responsible function. The IKE endpoint must be network-reachable, but no authentication or user interaction is required; only availability impact is reported.
