CVE-2025-21607

Vyper is a Pythonic Smart Contract Language for the EVM. When the Vyper Compiler uses the precompiles EcRecover 0x1 and Identity 0x4, the success flag of the call is not checked. As a consequence an attacker can provide a specific amount of gas to make these calls fail but let the overall executi...
