Published Dec 9, 2025

Updated

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

cpufreq: qcom: fix memory leak in error path

If for some reason the speedbin length is incorrect, then there is a memory leak in the error path because we never free the speedbin buffer. This commit fixes the error path to always free the speedbin buffer.
