NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-iscsi-initiator-utils package and not the python3-iscsi-initiator-utils package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

A flaw was found in open-iscsi. This vulnerability allows a remote attacker on the same local network segment to cause a Denial of Service (DoS) in the iscsiuio daemon. By sending a specially crafted Internet Control Message Protocol version 6 (ICMPv6) Router Advertisement with a zero-length option, the attacker can trigger an infinite loop. This leads to sustained CPU usage, rendering the daemon unresponsive and impacting system availability. A secondary risk of out-of-bounds reads exists with a short IPv6 payload, though no memory corruption or data exposure has been confirmed.
