CVE-2022-21634Network attack vector

Unauthenticated runtime hang or repeated crash

Published Oct 18, 2022 · Updated Sep 24, 2024

Denial of service in Oracle GraalVM Enterprise Edition 20.3.7, 21.3.3, and 22.2.0 allows remote attackers to hang or repeatedly crash it. Oracle identifies the LLVM Interpreter as the affected component but has not published the defective operation or triggering input. Network access over multiple supported protocols is sufficient without authentication, and the reported impact is limited to service interruption.
