5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Details

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.
