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.

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service.
