CyberRota Analysis

AI-Generated

The vulnerability affects the Linux kernel, specifically in the OpenVPN (ovpn) module, where improper handling of socket ownership can lead to out-of-bounds reads due to incorrect dereferencing of sk_user_data. This flaw could potentially allow an attacker to exploit memory access issues, leading to information disclosure or system instability. Organizations using Linux systems with OpenVPN should prioritize addressing this vulnerability to mitigate potential security risks.

Original NVD 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.
