Overview

About vulnerability

In the Linux kernel, the following vulnerability has been resolved:

firmware: arm_scmi: Fix OOB in scmi_power_name_get()

scmi_power_name_get() does not validate the domain number passed by the external caller, which may lead to an out-of-bounds access.

Fix this by returning “unknown” for invalid domains, like scmi_reset_name_get() does.
