CVE-2024-27040

  3. CVE-2024-27040
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) { replay->funcs->replay_set_power_opt(replay, *power_opts, panel_inst); link->replay_settings.replay_power_opt_active = *power_opts; } If 'replay' is NULL, this will cause a null pointer dereference. Fixes the below found by smatch: drivers/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)

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amd/display: agregue la verificación NULL 'replay' en 'edp_set_replay_allow_active()' En la primera declaración if, estamos verificando si 'replay' es NULL. Pero en la segunda declaración if, no estamos verificando si 'replay' es NULL nuevamente antes de llamar a replay->funcs->replay_set_power_opt(). si (repetición == 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 'repetición' es NULL, esto provocará una desreferencia del puntero nulo. Corrige el siguiente error encontrado por smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_edp_panel_control.c:895 edp_set_replay_allow_active(): previamente asumimos que 'repetir' podría ser nulo (ver línea 887)
