net/llc/sysctl_net_llc.c in the Linux kernel before 3.19 uses an incorrect data type in a sysctl table, which allows local users to obtain potentially sensitive information from kernel memory or possibly have unspecified other impact by accessing a sysctl entry. net/llc/sysctl_net_llc.c en el kernel de Linux anterior a 3.19 utiliza un tipo de datos incorrecto en una tabla sysctl, lo que permite a usuarios locales obtener información sensible de la memoria del kernel o posiblemente tener otro impacto no especificado mediante el acceso a una entrada sysctl. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=6b8d9117ccb4f81b1244aafa7bc70ef8fa45fc49 http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00004.html http://www.debian.org/security/2015/dsa-3237 http://www.openwall.com/lists/oss-secu • CWE-17: DEPRECATED: Code •

The IPv4 implementation in the Linux kernel before 3.18.8 does not properly consider the length of the Read-Copy Update (RCU) grace period for redirecting lookups in the absence of caching, which allows remote attackers to cause a denial of service (memory consumption or system crash) via a flood of packets. La implementación IPv4 en el kernel de Linux anterior a 3.18.8 no considera correctamente la longitud del periodo de gracia de Read-Copy Update (RCU) para redirigir búsquedas en la ausencia de cacheo, lo que permite a atacantes remotos causar una denegación de servicio (corrupción de memoria o caída de sistema) a través de una inundación de paquetes. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=df4d92549f23e1c037e83323aff58a21b3de7fe0 http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00009.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.18.8 http://www.openwall.com/lists/oss-security/2015/02/03/13 http://www.securityfocus.com& • CWE-17: DEPRECATED: Code •

Xen 3.3.x through 4.5.x and the Linux kernel through 3.19.1 do not properly restrict access to PCI command registers, which might allow local guest OS users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response. Xen 3.3.x hasta la versión 4.5.x y en el kernel de Linux hasta la versión 3.19.1 no restringe adecuadamente el acceso al registro de comandos PCI, lo que podría permitir a usuarios locales del SO invitados provocar una denegación de servicio (interrupción no enmascarable y caída del host) deshabilitando (1) la memoria o (2) la descodificación I/O para un dispositivo PCI Express posteriormente accediendo al dispositivo, lo que desencadena una respuesta Unsupported Request (UR). • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=af6fc858a35b90e89ea7a7ee58e66628c55c776b http://lists.fedoraproject.org/pipermail/package-announce/2015-April/155804.html http://lists.fedoraproject.org/pipermail/package-announce/2015-April/155854.html http://lists.fedoraproject.org/pipermail/package-announce/2015-April/155908.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152747.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00001.html http • CWE-264: Permissions, Privileges, and Access Controls •

https://notcve.org/view.php?id=CVE-2014-8159
The InfiniBand (IB) implementation in the Linux kernel package before 2.6.32-504.12.2 on Red Hat Enterprise Linux (RHEL) 6 does not properly restrict use of User Verbs for registration of memory regions, which allows local users to access arbitrary physical memory locations, and consequently cause a denial of service (system crash) or gain privileges, by leveraging permissions on a uverbs device under /dev/infiniband/. La implementación InfiniBand (IB) en el paquete del kernel de Linux anterior a 2.6.32-504.12.2 en Red Hat Enterprise Linux (RHEL) 6 no restringe adecuadamente el uso de User Verbs para el registro de regiones de memoria, lo que permite a usaurios locales acceder de forma arbitraria a ubicaciones de la memoria física, y consecuentemente causar una denegación de servicio (caída del sistema) u obtener privilegios, aprovechando permisos en un dispositivo uverbs bajo /dev/infiniband/. It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from user space via the (u)verbs API. A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges on the system. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10705 http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152747.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg0001 • CWE-190: Integer Overflow or Wraparound CWE-264: Permissions, Privileges, and Access Controls •

The pmd_none_or_trans_huge_or_clear_bad function in include/asm-generic/pgtable.h in the Linux kernel before 3.13 on NUMA systems does not properly determine whether a Page Middle Directory (PMD) entry is a transparent huge-table entry, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted MADV_WILLNEED madvise system call that leverages the absence of a page-table lock. La función pmd_none_or_trans_huge_or_clear_bad en include/asm-generic/pgtable.h en el Kernel de Linux anterior a 3.13 en sistemas NUMA no determina adecuadamente si una entrada de direcotrio Page Middle Directory (PMD) es una entrada transparente de huge-table, lo que permite a usuarios locales causar una denegación de servicio (referencia a puntero nulo y caída del sistema) o la posibilidad de tener otro impacto no especificado a través de una llamada al sistema MADV_WILLNEED que se aprovecha de la ausencia del bloqueo de la tabla de páginas. A NULL pointer dereference flaw was found in the way the Linux kernel's madvise MADV_WILLNEED functionality handled page table locking.
