CVE-2023-36184Network attack vector

Node crash via unbounded Move value nesting

Published Sep 8, 2023 · Updated Sep 26, 2024

Stack exhaustion in Mysten Labs Sui blockchain 1.2.0 allows remote attackers to crash network nodes using deeply nested Move values. The Move VM constructs nested struct and vector values without enforcing a maximum value depth, allowing recursive processing to exhaust the process stack. Exploitation requires a crafted Move program to reach node execution; the documented consequence is service interruption without confidentiality or integrity impact.
