A vulnerability in the Linux kernel's powerpc/xive subsystem caused a kmemleak due to incorrect chip_data lookup. This issue was addressed in the Linux kernel updates released for various Ubuntu 26.04 LTS packages. The vulnerability has a medium severity with a CVSS score of 5.5 and impacts system availability. Multiple Linux kernel subsystems were updated to fix this and other security issues. Users are advised to update to the fixed kernel versions and reboot to apply the patches.

The Linux kernel vulnerability CVE-2026-46141 involves a kmemleak caused by an incorrect chip_data lookup in the powerpc/xive subsystem. This flaw results in unreferenced kernel memory leaks, which can impact system stability and availability. The issue was resolved in Linux kernel versions released for Ubuntu 26.04 LTS and related variants. The vulnerability has a CVSS 3.1 score of 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H), indicating local attack vector with low complexity and privileges required, no user interaction, unchanged scope, no confidentiality or integrity impact, but high impact on availability. The vendor advisory confirms patches are available and recommends updating to specific fixed kernel package versions. The update requires a system reboot and recompilation of third-party kernel modules due to ABI changes.
