      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmailbox: zynqmp-ipi: Fix SGI cleanup on unbind\n\nThe driver incorrectly determines SGI vs SPI interrupts by checking IRQ\nnumber < 16, which fails with dynamic IRQ allocation. During unbind,\nthis causes improper SGI cleanup leading to kernel crash.\n\nAdd explicit irq_type field to pdata for reliable identification of SGI\ninterrupts (type-2) and only clean up SGI resources when appropriate."

      "value": "En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:\n\nmailbox: zynqmp-ipi: Corrección de la limpieza de SGI al desvincular\n\nEl controlador determina incorrectamente las interrupciones SGI frente a SPI al comprobar que el número de IRQ es inferior a 16, lo que falla con la asignación dinámica de IRQ. Durante la desvinculación, esto provoca una limpieza incorrecta de SGI, provocando un fallo del kernel.\n\nSe añade un campo “irq_type” explícito a “pdata” para la identificación fiable de las interrupciones SGI (tipo 2) y solo se limpian los recursos SGI cuando es apropiado."
