CVE-2026-80735

HighCVSS 7.3/10Last modified Sep 4, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

ovpn: ensure socket is owned by ovpn before deref sk_user_data

Some subsystems, like BPF SOCKMAP, set sk_user_data without actually setting the encap_type.

For this reason, we must make sure that the type is the one ovpn expects before dereferencing sk_user_data.

Failing to do so may lead to out-of-bounds reads.
