Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: clk: mediatek: Drop __initconst from gates Since commit 8ceff24a754a ("clk: mediatek: clk-gate: Refactor mtk_clk_register_gate to use mtk_gate struct") the mtk_gate structs are no longer just used for initialization/registration, but also at runtime. So drop __initconst annotations.

Executive Summary

This vulnerability relates to the Linux kernel's MediaTek clock driver. Specifically, a change was made to drop the __initconst annotation from mtk_gate structs because these structs are now used not only during initialization and registration but also at runtime. The __initconst annotation was originally intended for data used only during initialization, so keeping it at runtime could cause issues.
