ExecuTorch Integer Overflow Vulnerability Leading to Memory Allocation Issues and Potential Code Execution

A vulnerability allowing integer overflow in the loading of ExecuTorch models has been identified. This overflow can cause memory regions to be allocated in smaller sizes than expected, which may lead to code execution or other negative effects. The issue affects ExecuTorch versions prior to commit 8f062d3f661e20bb19b24b767b9a9a46e8359f2b.

Impact

Exploitation of this vulnerability could result in arbitrary code execution or other undesirable effects due to improper memory allocation.
