CVE-2025-37850

5.5 · MEDIUM
Published May 9, 2025 linux CWE-369 EPSS 0.27% (19th pctl)

Overview

CVE-2025-37850 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 9, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

pwm: mediatek: Prevent divide-by-zero in pwm_mediatek_config()

With CONFIG_COMPILE_TEST && !CONFIG_HAVE_CLK, pwm_mediatek_config() has a

divide-by-zero in the following line:

do_div(resolution, clk_get_rate(pc->clk_pwms[pwm->hwpwm]));

due to the fact that the !CONFIG_HAVE_CLK version of clk_get_rate()

returns zero.

This is presumably just a theoretical problem: COMPILE_TEST overrides

the dependency on RALINK which would select COMMON_CLK. Regardless it's

a good idea to check for the error explicitly to avoid divide-by-zero.

Fixes the following warning:

drivers/pwm/pwm-mediatek.o: warning: objtool: .text: unexpected end of section

[ukleinek: s/CONFIG_CLK/CONFIG_HAVE_CLK/]

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
