Description

A flaw was found in the cmd/compile package in the Go standard library. The compiler fails to correctly check for integer overflow or underflow in arithmetic operations involving loop induction variables. As a result, the compiler allows invalid memory indexing to occur at runtime, potentially leading to memory corruption.
