Overview

CVE-2026-64377 is a known-severity vulnerability. It was published on July 25, 2026.

Technical 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->driver_data.

qcom_cpufreq_hw_cpu_exit() currently calls kfree() on policy->driver_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.

How can CyberStrike help with CVE-2026-64377?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-64377 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
