## Stack Overflow Vulnerability

A stack overflow vulnerability occurs when a smart contract exceeds the 1024 element stack limit, causing the transaction to revert. This often happens in recursive functions or deeply nested control structures where the EVM cannot allocate enough stack space to complete the operation.

In DeFi, this can be exploited or triggered by malicious input designed to force the contract into a state where it cannot process the transaction. Proper auditing involves analyzing the call graph to ensure that no execution path exceeds the maximum depth allowed by the EVM.

Mitigation strategies include iterative rather than recursive implementations and breaking down large functions into smaller, modular components.
