The cma_req_handler function in drivers/infiniband/core/cma.c in the Linux kernel 3.14.x through 3.14.1 attempts to resolve an RDMA over Converged Ethernet (aka RoCE) address that is properly resolved within a different module, which allows remote attackers to cause a denial of service (incorrect pointer dereference and system crash) via crafted network traffic. La función cma_req_handler en drivers/infiniband/core/cma.c en el kernel de Linux 3.14.x hasta 3.14.1 intenta resolver un RDMA sobre una dirección Converged Ethernet (también conocido como RoCE) que se resuelve debidamente dentro de un módulo diferente, lo que permite a atacantes remotos causar una denegación de servicio (referencia a puntero incorrecto y caída de sistema) a través de trafico de red manipulado. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=b2853fd6c2d0f383dbdf7427e263eb576a633867 http://www.openwall.com/lists/oss-security/2014/04/10/9 http://www.securityfocus.com/bid/66716 https://bugzilla.redhat.com/show_bug.cgi?id=1085415 https://github.com/torvalds/linux/commit/b2853fd6c2d0f383dbdf7427e263eb576a633867 • CWE-20: Improper Input Validation •

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') •

https://notcve.org/view.php?id=CVE-2014-2678
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). A local, unprivileged user could use this flaw to crash the system. • http://linux.oracle.com/errata/ELSA-2014-0926-1.html http://linux.oracle.com/errata/ELSA-2014-0926.html http://lists.fedoraproject.org/pipermail/package-announce/2014-April/131276.html http://secunia.com/advisories/59386 http://secunia.com/advisories/60130 http://secunia.com/advisories/60471 http://www.openwall.com/lists/oss-security/2014/03/31/10 http://www.securityfocus.com/bid/66543 https://lkml.org/lkml/2014/3/29/188 https://access.redhat.com/security/cve/CV • CWE-476: NULL Pointer Dereference •
