n the Linux kernel, the following vulnerability has been resolved: media: intel/ipu6: do not handle interrupts when device is disabled Some IPU6 devices have shared interrupts. We need to handle properly case when interrupt is triggered from other device on shared irq line and IPU6 itself disabled. In such case we get 0xffffffff from ISR_STATUS register and handle all irq's cases, for what we are not not prepared and usually hang the whole system. To avoid the issue use pm_runtime_get_if_active() to check if the device is enabled and prevent suspending it when we handle irq until the end of irq. Additionally use synchronize_irq() in suspend

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: media: intel/ipu6: no gestionan interrupciones cuando el dispositivo está deshabilitado Algunos dispositivos IPU6 tienen interrupciones compartidas. Necesitamos gestionar adecuadamente el caso cuando la interrupción se activa desde otro dispositivo en la línea irq compartida y el propio IPU6 está deshabilitado. En tal caso, obtenemos 0xffffffff del registro ISR_STATUS y gestionamos todos los casos de irq, para lo cual no estamos preparados y generalmente colgamos todo el sistema. Para evitar el problema, use pm_runtime_get_if_active() para verificar si el dispositivo está habilitado y evitar suspenderlo cuando gestionamos irq hasta el final de irq. Además, usesynchronous_irq() en suspensión
