CVE-2026-98785
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:
drm/amd/display: comprobar si dc_state_create_copy() devuelve NULL en dm_suspend
dc_state_create_copy() puede devolver NULL si falla la asignación de memoria. dm_suspend() solo omite de forma condicional dm_gpureset_toggle_interrupts() y continúa la ejecución, devolviendo éxito. Después, dm_resume() desreferencia el cached_dc_state NULL en link_enc_cfg_copy() y en el siguiente bucle sobre dc_state->stream_count, lo que provoca un fallo durante la recuperación tras el reinicio de la GPU.
Devolver -ENOMEM inmediatamente si la copia falla, de modo que el invocador aborte la suspensión en lugar de dejar un estado en caché NULL para la reanudación.
