A vulnerability in the Linux kernel related to the use of WARN_ON_ONCE when accessing the forward path array has been resolved. The issue involved a warning that could be triggered if userspace constructed a sufficiently long forward path, particularly with recent IPIP tunnel support. The warning was removed to address this unlikely but possible condition. Join the discussion | GCVE Database | 05/27/2026, 15:33:12 UTC Added: 06/26/2026, 22:06:43 UTC |
A medium severity vulnerability (CVE-2026-45847) in the Linux kernel related to the removal of WARN_ON_ONCE when accessing the forward path array has been resolved. The issue is linked to recent support for IPIP tunnels which could trigger this warning if userspace constructs a sufficiently long forward path. This vulnerability is part of a broader set of security fixes addressing multiple subsystems in the Linux kernel. A patch is available and users are advised to update their systems and reboot to apply the fixes. The update may require recompilation of third-party kernel modules due to ABI changes.
