Official Description
Buffer overflow in ovpn‑dco‑win version 2.8.0 allows local attackers to cause a system crash by sending too large packets to the remote peer when the AEAD tag appears at the end of the encrypted packet
Technical Analysis
CVE-2026-2738 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation does not require any privileges, though user interaction (P) is needed, which slightly reduces the risk of mass automated attacks.
