  "details": "In the Linux kernel, the following vulnerability has been resolved:  cpufreq: Fix hotplug-suspend race during reboot  During system reboot, cpufreq_suspend() is called via the kernel_restart() -\u003e device_shutdown() path. Unlike the normal system suspend path, the reboot path does not call freeze_processes(), so userspace processes and kernel threads remain active.  This allows CPU hotplug operations to run concurrently with cpufreq_suspend(). The original code has no synchronization with CPU hotplug, leading to a race condition where governor_data can be freed by the hotplug path while cpufreq_suspend() is still accessing it, resulting in a null pointer dereference:    Unable to handle kernel NULL pointer dereference   Call Trace:    do_kernel_fault+0x28/0x3c    cpufreq_suspend+0xdc/0x160    device_shutdown+0x18/0x200    kernel_restart+0x40/0x80    arm64_sys_reboot+0x1b0/0x200  Fix this by adding cpus_read_lock()/cpus_read_unlock() to cpufreq_suspend() to block CPU hotplug operations while suspend is in progress.
