CVE-2026-97419 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 5.10.271, 5.15.222, 6.1.189, 6.6.158, 6.12.111, 6.18.53 or higher.
Overview
Affected versions of this package are vulnerable to Exposure of Sensitive Information to an Unauthorized Actor due to improper handling of network namespace isolation in the hsr_nl_ringerror and hsr_nl_nodedown functions. An attacker can obtain sensitive information from other network namespaces by listening for broadcasted events that include peer node MAC addresses and slave port interface indices.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
