CVE-2024-36740Network attack vector

Service interruption via unchecked negative tensor index

Published Jun 6, 2024 · Updated Feb 13, 2025

Improper index validation in OneFlow 0.9.1 allows remote attackers to interrupt a process with an excessively negative tensor index. Tensor indexing accepts a negative index whose magnitude exceeds the indexed dimension's size instead of rejecting it before access. Reachability requires attacker-controlled tensor indexing; public records do not state whether the interruption is a crash, hang, or another failure mode.
