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 •

The arch_dup_task_struct function in the Transactional Memory (TM) implementation in arch/powerpc/kernel/process.c in the Linux kernel before 3.13.7 on the powerpc platform does not properly interact with the clone and fork system calls, which allows local users to cause a denial of service (Program Check and system crash) via certain instructions that are executed with the processor in the Transactional state. La función arch_dup_task_struct en la implementación Transactional Memory (TM) en arch/powerpc/kernel/process.c en el kernel de Linux anterior a 3.13.7 en la plataforma powerpc no interactúa debidamente con las llamadas de sistema clon y fork, lo que permite a usuarios locales causar una denegación de servicio (comprobación de programa y caída de sistema) a través de ciertas instrucciones que son ejecutadas con el procesador en el estado transaccional. A flaw was found in the way the Linux kernel performed forking inside of a transaction. A local, unprivileged user on a PowerPC system that supports transactional memory could use this flaw to crash the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=621b5060e823301d0cba4cb52a7ee3491922d291 http://secunia.com/advisories/57436 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.13.7 http://www.openwall.com/lists/oss-security/2014/03/30/5 http://www.securityfocus.com/bid/66477 https://exchange.xforce.ibmcloud.com/vulnerabilities/92113 https://github.com/torvalds/linux/commit/621b5060e823301d0cba4cb52a7ee3491922d291 https://www.kernel.org/pub/linux/kernel/ • CWE-20: Improper Input Validation •
