In the Linux kernel, the following vulnerability has been resolved:

drm/amd/pm: Update intermediate power state for SI

Update the current state as boot state during dpm initialization.
During the subsequent initialization, set_power_state gets called to
transition to the final power state. set_power_state refers to values
from the current state and without current state populated, it could
result in NULL pointer dereference.

For ex: on platforms where PCI speed change is supported through ACP
