Description

A flaw was found in the Linux kernel's qcom-cpufreq-hw driver. This vulnerability, a double free, occurs due to incorrect memory handling when a device is detached. Specifically, the system attempts to release memory that is already managed, leading to a potential double free. This can result in system instability, memory corruption, or a denial of service (DoS), making the system unavailable to legitimate users.
