"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Add 'replay' NULL check in 'edp_set_replay_allow_active()'\n\nIn the first if statement, we're checking if 'replay' is NULL. But in\nthe second if statement, we're not checking if 'replay' is NULL again\nbefore calling replay->funcs->replay_set_power_opt().\n\nif (replay == NULL && force_static)\n return false;\n\n...\n\nif (link->replay_settings.replay_feature_enabled &&\n replay->funcs->replay_set_power_opt) {\n\treplay->funcs->replay_set_power_opt(replay, *power_opts, panel_inst);\n\tlink->replay_settings.replay_power_opt_active = *power_opts;\n}\n\nIf 'replay' is NULL, this will cause a null pointer dereference.\n\nFixes the below found by smatch:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_edp_panel_control.c:895 edp_set_replay_allow_active() error: we previously assumed 'replay' could be null (see line 887)"

"value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: drm/amd/display: agregue la verificaci\u00f3n NULL 'replay' en 'edp_set_replay_allow_active()' En la primera declaraci\u00f3n if, estamos verificando si 'replay' es NULL. Pero en la segunda declaraci\u00f3n if, no estamos verificando si 'replay' es NULL nuevamente antes de llamar a replay->funcs->replay_set_power_opt(). si (repetici\u00f3n == NULL && force_static) devuelve falso; ... if (enlace->replay_settings.replay_feature_enabled && replay->funcs->replay_set_power_opt) { replay->funcs->replay_set_power_opt(replay, *power_opts, panel_inst); enlace->replay_settings.replay_power_opt_active = *power_opts; } Si 'repetici\u00f3n' es NULL, esto provocar\u00e1 una desreferencia del puntero nulo.
