Descriptions
In the Linux kernel, the following vulnerability has been resolved:
pci_iounmap(): Fix MMIO mapping leak
The #ifdef ARCH_HAS_GENERIC_IOPORT_MAP accidentally also guards iounmap(),
which means MMIO mappings are leaked.
Move the guard so we call iounmap() for MMIO mappings.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: pci_iounmap(): corrige la fuga de mapeo MMIO El #ifdef ARCH_HAS_GENERIC_IOPORT_MAP accidentalmente también protege iounmap(), lo que significa que se filtraron los mapeos MMIO. Mueva la guardia para que llamemos a iounmap() para asignaciones MMIO.
