NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-core package and not the kernel-uek-core package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

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-&gt;clk_pwms[pwm-&gt;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
