CVE-2024-42100 Information

Description

In the Linux kernel the following vulnerability has been resolved:

clk: sunxi-ng: common: Don’t call hw_to_ccu_common on hw without common

In order to set the rate range of a hw sunxi_ccu_probe calls hw_to_ccu_common() assuming all entries in desc->ccu_clks are contained in a ccu_common struct. This assumption is incorrect and in consequence causes invalid pointer de-references.

Remove the faulty call. Instead add one more loop that iterates over the ccu_clks and sets the rate range if required.
