      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: rkisp1: Fix IRQ handling due to shared interrupts\n\nThe driver requests the interrupts as IRQF_SHARED, so the interrupt\nhandlers can be called at any time. If such a call happens while the ISP\nis powered down, the SoC will hang as the driver tries to access the\nISP registers.\n\nThis can be reproduced even without the platform sharing the IRQ line:\nEnable CONFIG_DEBUG_SHIRQ and unload the driver, and the board will\nhang.\n\nFix this by adding a new field, 'irqs_enabled', which is used to bail\nout from the interrupt handler when the ISP is not operational."

      "value": " 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 est\u00e1 apagado, el SoC se bloquear\u00e1 cuando el controlador intente acceder a los registros del ISP. Esto se puede reproducir incluso sin que la plataforma comparta la l\u00ednea IRQ: habilite CONFIG_DEBUG_SHIRQ y descargue el controlador, y la placa se bloquear\u00e1. Solucione este problema agregando un nuevo campo, 'irqs_enabled', que se utiliza para salir del controlador de interrupciones cuando el ISP no est\u00e1 operativo."
