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

drm/amd/display: Add 'replay' NULL check in 'edp_set_replay_allow_active()'

In the first if statement, we're checking if 'replay' is NULL. But in
the second if statement, we're not checking if 'replay' is NULL again
before calling replay->funcs->replay_set_power_opt().

if (replay == NULL && force_static)
    return false;

...

if (link->replay_settings.replay_feature_enabled &&
    replay->funcs->replay_set_power_opt) {
	rep
