CVSS: 3.3EPSS: 0%CPEs: 9EXPL: 2CVE-2015-2922 – kernel: denial of service (DoS) attack against IPv6 network stacks due to improper handling of Router Advertisements.
https://notcve.org/view.php?id=CVE-2015-2922
The ndisc_router_discovery function in net/ipv6/ndisc.c in the Neighbor Discovery (ND) protocol implementation in the IPv6 stack in the Linux kernel before 3.19.6 allows remote attackers to reconfigure a hop-limit setting via a small hop_limit value in a Router Advertisement (RA) message. La función ndisc_router_discovery en net/ipv6/ndisc.c en la implementación de protocolo Neighbor Discovery (ND) en la pila IPv6 en el kernel de Linux anterior a 3.19.6 permite a atacantes remotos reconfigurar una configuración 'hop-limit' a través de un valor hop_limit pequeño en un mensaje Router Advertisement (RA). It was found that the Linux kernel's TCP/IP protocol suite implementation for IPv6 allowed the Hop Limit value to be set to a smaller value than the default one. An attacker on a local network could use this flaw to prevent systems on that network from sending or receiving network packets. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=6fd99094de2b83d1d4c8457f2c83483b2828e75a 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.opensuse.org/opensuse-security-announce/2015-07/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00011.html http:&# • CWE-17: DEPRECATED: Code CWE-454: External Initialization of Trusted Variables or Data Stores •

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 •

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 •
