CVE-2026-18725Source published Source updated
AI_ONLY_REPORT package: iscsi-initiator-utils-6.2.1.11-0.git4b3e853.el10 ------ Summary: Out-of-Bounds Write and Information Disclosure via Unvalidated IPv6 Payload Length: crafted ICMPv6 Echo Requests can cause `iscsiuio` to trust an inflated `ipv6_plen` larger than the actual received payload, leading to MTU-bounded out-of-bounds reads and a potential one-byte out-of-bounds write that may disclose data beyond the valid packet boundary. Requirements to exploit: Adjacent-network access on the same L2 segment as a system running `iscsiuio` on an interface that processes IPv6/NDP traffic, plus the ability to send a crafted ICMPv6 Echo Request with a forged `IPv6.plen`. No authentication or user interaction is required. Component affected: `iscsi-initiator-utils` (`iscsiuio`)…

- Mitigation guidance
- To mitigate this issue, ensure that `iscsiuio`-managed interfaces are restricted to trusted L2 network segments. If feasible for your operational environment, disable IPv6 on interfaces where `iscsiuio` is active and not strictly required to process IPv6 traffic. Alternatively, implement firewall rules to filter ICMPv6 Echo Requests before they reach the `iscsiuio` process on affected systems. Changes to network configurations may require a network service restart to take effect, which could temporarily impact network connectivity.
