Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 已修复 Linux 内核中的下列漏洞：powercap: arm_scmi: Remove recursion while parsing zones Powercap zones can be defined as arranged in a hierarchy of trees and when registering a zone with powercap_register_zone(), the kernel powercap subsystem expects this to happen starting from the root zones down to the leaves; on the other side, de-registration by powercap_deregister_zone() must begin from the leaf zones. Available SCMI powercap zones are retrieved dynamically from the platform at probe time and, while any defined hierarchy between the zones is described properly in the zones descriptor, the platform returns the availables zones with no particular well-defined order: as a consequence, the trees possibly composing the hierarchy of zones have to be somehow walked properly to register the retrieved zones from the root. Currently the ARM SCMI Powercap driver walks the zones using a recursive algorithm; this approach, even though correct and tested can lead to kernel stack overflow when processing a returned hierarchy of zones composed by particularly high trees. Avoid possible kernel stack overflow by substituting the recursive approach with an iterative one supported by a dynamically allocated stack-like data structure. (CVE-2023-53428)
