Overview

CVE-2026-68341 is a high-severity vulnerability. It was published on August 10, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

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

ovpn: fix use after free in unlock_ovpn()

unlock_ovpn() iterates over the release_list using llist_for_each_entry()

and drops the peer reference inside the loop body via ovpn_peer_put().

If this drops the last reference, the peer is eventually freed. However,

llist_for_each_entry() reads peer->release_entry.next in the loop advance

expression, which runs after the body. By that time the peer may have

already been freed, resulting in a use after free when advancing to the

next list entry.

Fix this by using llist_for_each_entry_safe(), which caches the next

pointer before executing the loop body.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
