CVE-2026-68122

A flaw was found in the Linux kernel's ovpn module. A race condition in the TCP error handling paths can lead to a reference count leak. This occurs when an internal object's reference count is incremented twice but decremented only once, preventing the object from being properly released. Over...

CVE-2026-68342

A flaw was found in the Linux kernel's OpenVPN ovpn module. During the destruction of an ovpn UDP socket, a race condition can occur where a new peer is published before the old socket is fully released. This can lead to a use-after-free vulnerability, allowing an attacker to potentially cause a...

CVE-2026-45929

A flaw was found in the Linux kernel's ovpn module. A use-after-free vulnerability exists in the ovpnnetxmit function where a freed skb socket buffer pointer can be used for subsequent operations. This can occur when skbsharecheck frees the original skb if it is shared, leading to a stale pointer...
