NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_3_18-24_67-default package and not the kernel-livepatch-5_3_18-24_67-default package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients.
