Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak issue in the Linux kernel has been identified, specifically related to the thinkpad acpi module and the handling of EFCH MMIO resources. The problem arises because release resource() does not free the resource, unlike release mem region(), leading to a memory leak if the resource is not explicitly freed.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
