Descriptions
The ioapic_deliver function in virt/kvm/ioapic.c in the Linux kernel through 3.14.1 does not properly validate the kvm_irq_delivery_to_apic return value, which allows guest OS users to cause a denial of service (host OS crash) via a crafted entry in the redirection table of an I/O APIC. NOTE: the affected code was moved to the ioapic_service function before the vulnerability was announced.
La función ioapic_deliver en virt/kvm/ioapic.c en el kernel de Linux hasta 3.14.1 no valida debidamente el valor de vuelta kvm_irq_delivery_to_apic, lo que permite a usuarios invitados del sistema operativo causar una denegación de servicio (caída de sistema operativo anfitrión) a través de una entrada manipulada en la tabla de redirección de I/O APIC. NOTA: el código afectado fue trasladado a la función ioapic_service antes de que la vulnerabilidad fue anunciada.
Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or gain administrative privileges. A flaw was discovered in the Linux kernel virtual machine's (kvm) validation of interrupt requests (irq). A guest OS user could exploit this flaw to cause a denial of service (host OS crash). An information leak was discovered in the netfilter subsystem of the Linux kernel. An attacker could exploit this flaw to obtain sensitive information from kernel memory. Various other issues were also addressed.
