Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The Python package vyper, versions before 0.2.6, has a memory corruption bug that occurs when a function call is placed inside a tuple or used as an argument to another function call, because of an incorrect pointer to the top of the stack. The source does not describe what an attacker must do to trigger it or what the impact would be beyond memory corruption. Upgrade vyper to version 0.2.6 or later.
