  "title": "cpufreq: qcom-cpufreq-hw: Fix possible double free",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  cpufreq: qcom-cpufreq-hw: Fix possible double free  qcom_cpufreq.data is allocated with devm_kzalloc() in probe() as an array of per-domain data. qcom_cpufreq_hw_cpu_init() stores a pointer to one element of this array in policy-\u003Edriver_data.  qcom_cpufreq_hw_cpu_exit() currently calls kfree() on policy-\u003Edriver_data. This is not valid because the memory is devm-managed. For the first domain, this can free the devm-managed allocation while the devres entry is still active, leading to a possible double free when the platform device is later detached. For other domains, the pointer may refer to an element inside the array rather than the allocation base.  Remove the kfree(data) call and let devres release qcom_cpufreq.data.  This issue was found by a static analysis tool I am developing.",
