Vulnerability from fkie_nvd - Published: 2025-10-04 16:15 - Updated: 2026-06-17 06:45
Severity
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: cpufreq: davinci: Fix clk use after free The remove function first frees the clks and only then calls cpufreq_unregister_driver(). If one of the cpufreq callbacks is called just before cpufreq_unregister_driver() is run, the freed clks might be used.
