CVE-2025-12106 is a vulnerability in OpenVPN affecting versions 2.7_alpha1 through 2.7_rc1. The issue is described as insufficient argument validation during IP address parsing, specifically in IPv6 address parsing, which can cause a heap buffer over-read when invalid input is processed. Based on the provided content, malformed address input reaches parsing logic without adequate validation, resulting in an out-of-bounds read from heap memory. The available information indicates a memory-safety flaw in the address parsing path rather than a write primitive or confirmed code-execution condition.
