An update for multipath-tools is now available for openEuler-24.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-4156 Final 1.0 1.0 2026-09-30 Initial 2026-09-30 2026-09-30 openEuler SA Tool V1.0 2026-09-30 multipath-tools security update An update for multipath-tools is now available for openEuler-24.03-LTS-SP3 This package provides the multipath tool and the multipathd daemon to manage dm-multipath devices. multipath can detect and set up multipath maps. multipathd sets up multipath maps automatically, monitors path devices for failure, removal, or addition, and applies the necessary changes to the multipath maps to ensure continuous availability of the map devices. Security Fix(es): A flaw was found in `multipathd`. A local attacker with access to the `multipathd` UNIX control socket can exploit this vulnerability by sending valid commands and then ceasing to read replies. This action can cause the `multipathd` listener thread to block, leading to a Denial of Service (DoS) where legitimate Inter-Process Communication (IPC) operations may hang or time out. This issue does not result in privilege escalation, arbitrary code execution, or impact data confidentiality or integrity.(CVE-2026-89329) An update for multipath-tools is now available for openEuler-24.03-LTS-SP3. openEuler Security has rated this update as having a security impact of medium.
