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. • http://git.kernel.org/cgit/virt/kvm/kvm.git/commit/?id=5678de3f15010b9022ee45673f33bcfc71d47b60 http://www.openwall.com/lists/oss-security/2014/04/07/2 https://bugzilla.redhat.com/show_bug.cgi?id=1081589 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2014-2706
Race condition in the mac80211 subsystem in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via network traffic that improperly interacts with the WLAN_STA_PS_STA state (aka power-save mode), related to sta_info.c and tx.c. Condición de carrera en el subsistema mac80211 en el kernel de Linux anterior a 3.13.7 permite a atacantes remotos causar una denegación de servicio (caída de sistema) a través de trafico de red que no interactúa debidamente con el estado WLAN_STA_PS_STA (también conocido como el modo power-save), relacionado con sta_info.c y tx.c. A race condition flaw was found in the way the Linux kernel's mac80211 subsystem implementation handled synchronization between TX and STA wake-up code paths. A remote attacker could use this flaw to crash the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=1d147bfa64293b2723c4fec50922168658e613ba http://linux.oracle.com/errata/ELSA-2014-3052.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00007.html http://secunia.com/advisories/60613 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.13.7 http://www.openwall.com/lists/oss-security/2014/04/01/8 http:/&# • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

The rds_iw_laddr_check function in net/rds/iw.c in the Linux kernel through 3.14 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a bind system call for an RDS socket on a system that lacks RDS transports. La función rds_iw_laddr_check en net/rds/iw.c en el kernel de Linux hasta 3.14 permite a usuarios locales causar una denegación de servicio (referencia a puntero nulo y caída de sistema) o posiblemente tener otro impacto no especificado a través de una llamada de sistema bind para un socket RDS en un sistema que carece de transportes RDS. A NULL pointer dereference flaw was found in the rds_iw_laddr_check() function in the Linux kernel's implementation of Reliable Datagram Sockets (RDS).
