Descriptions

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

media: rkisp1: Fix IRQ handling due to shared interrupts

The driver requests the interrupts as IRQF_SHARED, so the interrupt
handlers can be called at any time. If such a call happens while the ISP
is powered down, the SoC will hang as the driver tries to access the
ISP registers.

This can be reproduced even without the platform sharing the IRQ line:
Enable CONFIG_DEBUG_SHIRQ and unload the driver, and the board will
hang.

Fix this by adding a new field, 'irqs_enabled', which is used to bail
out from the interrupt handler when the ISP is not operational.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: media: rkisp1: Corrige el manejo de IRQ debido a interrupciones compartidas. El controlador solicita las interrupciones como IRQF_SHARED, por lo que se puede llamar a los controladores de interrupciones en cualquier momento. Si se produce una llamada de este tipo mientras el ISP está apagado, el SoC se bloqueará cuando el controlador intente acceder a los registros del ISP. Esto se puede reproducir incluso sin que la plataforma comparta la línea IRQ: habilite CONFIG_DEBUG_SHIRQ y descargue el controlador, y la placa se bloqueará. Solucione este problema agregando un nuevo campo, 'irqs_enabled', que se utiliza para salir del controlador de interrupciones cuando el ISP no está operativo.
