CVE-2024-31580

Process crash via unchecked JIT tuple inputs

Published Apr 17, 2024 · Updated Mar 28, 2025

Heap buffer overflow in PyTorch before 2.2.0 allows attackers to crash a process through malformed JIT tuple bytecode. The tupleConstruct function fails to verify that num_inputs does not exceed the interpreter stack size before accessing tuple inputs. Triggering the flaw requires a target process to execute the crafted JIT input; the reported consequence is a process crash.
