Descriptions
In the Linux kernel, the following vulnerability has been resolved:
ARM: footbridge: fix PCI interrupt mapping
Since commit 30fdfb929e82 ("PCI: Add a call to pci_assign_irq() in
pci_device_probe()"), the PCI code will call the IRQ mapping function
whenever a PCI driver is probed. If these are marked as __init, this
causes an oops if a PCI driver is loaded or bound after the kernel has
initialised.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ARM: footbridge: corrige el mapeo de interrupciones PCI Desde el commit 30fdfb929e82 ("PCI: agregue una llamada a pci_assign_irq() en pci_device_probe()"), el código PCI llamará a la función de mapeo IRQ cada vez que se prueba un controlador PCI. Si están marcados como __init, esto provoca un error si se carga o enlaza un controlador PCI después de que el kernel se haya inicializado.
