Type:

CWE-476 NULL Pointer Dereference

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 return 0 if unavailable, matching the existing fallback behavior in __dtpm_cpu_setup(). [ rjw: Drop an excess empty code line ]
