Description
In the Linux kernel, the following vulnerability has been resolved:
powercap: dtpm_cpu: Fix NULL pointer dereference in get_pd_power_uw()
The get_pd_power_uw() function can crash with a NULL pointer dereference
when em_cpu_get() returns NULL. This occurs when a CPU becomes impossible
during runtime, causing get_cpu_device() to return NULL, which propagates
through em_cpu_get() and leads to a crash when em_span_cpus() dereferences
the NULL pointer.
Add a NULL check after em_cpu_get() and retur…
