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 RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

A flaw was found in the iscsiuio component of open-iscsi. The IPv6 Neighbor Discovery handler accesses link-layer address options at a fixed offset without verifying the packet contains them. Additionally, the ARP table is updated unconditionally with attacker-controlled addresses from the packet headers. An attacker on the same network segment can send a minimal Neighbor Advertisement to poison the ARP table and redirect network traffic.
