A vulnerability in the Linux kernel hwmon subsystem (powerz) was resolved by avoiding cacheline sharing for DMA buffers, which could cause issues depending on architecture. The flaw involved transfer buffers sharing cachelines with mutexes, problematic for DMA usage. The fix uses high-level DMA helpers to prevent cacheline sharing. This vulnerability is part of a broader set of Linux kernel security issues addressed in recent updates. The vulnerability has a medium severity with a CVSS score of 5.5 and affects numerous specific Linux kernel versions prior to 7.0.0-27.27. A patch is available and included in updated Linux kernel packages.

The Linux kernel vulnerability CVE-2026-46007 involves the hardware monitoring (hwmon) subsystem on powerz architecture, where DMA transfer buffers could share cachelines with mutexes, potentially causing problematic behavior. The fix applies high-level DMA helpers to ensure cacheline sharing does not occur. This issue is addressed in the Linux kernel updates released by Ubuntu and others, which include numerous other kernel security fixes. The vulnerability affects many specific kernel versions prior to 7.0.0-27.27, as detailed in the affectedVersions list. The vendor advisory confirms that patches are available and users should update to the fixed kernel versions.
