| Doc Text: |
A flaw was found in vyper. An incorrect stack pointer calculation occurs when internal function calls are evaluated within tuples or nested calls, leading to memory corruption in compiled contracts. A remote caller interacting with an affected smart contract can exploit this issue to produce corrupted return values or pass unintended arguments to external calls, compromising the integrity of contract execution.
