CVE-2025-37972

Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:
20/05/2025
Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Input: mtk-pmic-keys - fix possible null pointer dereference<br /> <br /> In mtk_pmic_keys_probe, the regs parameter is only set if the button is<br /> parsed in the device tree. However, on hardware where the button is left<br /> floating, that node will most likely be removed not to enable that<br /> input. In that case the code will try to dereference a null pointer.<br /> <br /> Let&amp;#39;s use the regs struct instead as it is defined for all supported<br /> platforms. Note that it is ok setting the key reg even if that latter is<br /> disabled as the interrupt won&amp;#39;t be enabled anyway.
