CVE-2024-42100

Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:

Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> clk: sunxi-ng: common: Don&amp;#39;t call hw_to_ccu_common on hw without common<br /> <br /> In order to set the rate range of a hw sunxi_ccu_probe calls<br /> hw_to_ccu_common() assuming all entries in desc-&gt;ccu_clks are contained<br /> in a ccu_common struct. This assumption is incorrect and, in<br /> consequence, causes invalid pointer de-references.<br /> <br /> Remove the faulty call. Instead, add one more loop that iterates over<br /> the ccu_clks and sets the rate range, if required.
