## Overview

The compiler is meant to unwrap pointers which are the operands of a memory move; a no-op interface conversion prevented the compiler from making the correct determination about non-overlapping moves, potentially leading to memory corruption at runtime.

## Affected

- `go < 1.25.9`
- `go >= 1.26.0, < 1.26.2`

## Remediation

Upgrade past the affected range:

- `go 1.26.2`
