USN-8286-1: OpenVPN vulnerabilities

Guannan Wang, Zhanpeng Liu, Guancheng Li, and Emma Reuter
discovered that OpenVPN incorrectly handled suitably malformed
packets with valid tls-crypt-v2 keys. An attacker could possibly use
this issue to cause OpenVPN to crash, resulting in a denial of
service. (CVE-2026-35058)

Guannan Wang, Zhanpeng Liu, and Guancheng Li discovered that
OpenVPN had a race condition in the TLS handshake process that could
leak packet data from a previous handshake under certain
circumstances. An attacker could possibly use this issue to obtain
sensitive information. (CVE-2026-40215)
