Description (CNA)
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.
