Description

A vulnerability was found in the Linux kernel's cpufreq subsystem. The dbs_data struct, which embeds a kobject, improperly attempts to free the struct using kfree() rather than through the proper release() method. This issue can lead to a use-after-free scenario, resulting in system instability, memory corruption, or potential arbitrary code execution.
