CVE-2024-50181 Information

Description

In the Linux kernel the following vulnerability has been resolved:

clk: imx: Remove CLK_SET_PARENT_GATE for DRAM mux for i.MX7D

For i.MX7D DRAM related mux clock the clock source change should ONLY be done done in low level asm code without accessing DRAM and then calling clk API to sync the HW clock status with clk tree it should never touch real clock source switch via clk API so CLK_SET_PARENT_GATE flag should NOT be added otherwise DRAM’s clock parent will be disabled when DRAM is active and system will hang.
