AI-suggested
A patch is available and should be applied to affected Linux kernel versions. The Ubuntu security advisory USN-8029-1 confirms that this and several other kernel vulnerabilities have been fixed. Users should update their Linux kernel packages to the fixed versions provided by their distribution to remediate this issue.
Description
A vulnerability in the Linux kernel's drm/i915 driver was resolved that could cause lock inversion when pinning a virtual memory area (VMA) to the GGTT address space on certain Intel processors (Cherry View family and Broxton generation SoCs with VTD enabled). This lock inversion involves a circular locking dependency between reservation_ww and cpu_hotplug locks, potentially leading to kernel warnings or deadlocks. The issue has been fixed in updated Linux kernel versions.
