The slhc_init function in drivers/net/slip/slhc.c in the Linux kernel through 4.2.3 does not ensure that certain slot numbers are valid, which allows local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call. La función slhc_init en drivers/net/slip/slhc.c en el kernel de Linux hasta la versión 4.2.3 no asegura que ciertos números de ranura sean válidos, lo que permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULL y caída del sistema) a través de una llamada PPPIOCSMAXCID ioctl manipulada. • http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00038.html http://lists.opensuse.org/opensuse-updates/2015-12/msg00039. •

The Direct Rendering Manager (DRM) subsystem in the Linux kernel through 4.x mishandles requests for Graphics Execution Manager (GEM) objects, which allows context-dependent attackers to cause a denial of service (memory consumption) via an application that processes graphics data, as demonstrated by JavaScript code that creates many CANVAS elements for rendering by Chrome or Firefox. El subsistema Direct Rendering Manager (DRM) en el kernel de Linux hasta la versión 4.x no maneja correctamente las peticiones para los objetos Graphics Execution Manager (GEM), lo que permite a atacantes dependientes del contexto causar una denegación de servicio (consumo de la memoria) a través de una aplicación que procesa datos gráficos, segun lo demostrado por el código JaScript que genera muchos elementos CANVAS para el renderizado de Chrome o Firefox. • https://bugzilla.kernel.org/show_bug.cgi?id=60533 • CWE-399: Resource Management Errors •

CVSS: 4.7EPSS: 0%CPEs: 1EXPL: 3CVE-2015-5283 – kernel: Creating multiple sockets when SCTP module isn't loaded leads to kernel panic
https://notcve.org/view.php?id=CVE-2015-5283
The sctp_init function in net/sctp/protocol.c in the Linux kernel before 4.2.3 has an incorrect sequence of protocol-initialization steps, which allows local users to cause a denial of service (panic or memory corruption) by creating SCTP sockets before all of the steps have finished. La función sctp_init en net/sctp/protocol.c en el kernel de Linux en versiones anteriores a 4.2.3 tiene una secuencia incorrecta de pasos de inicialización de protocolo, lo que permite a usuarios locales provocar una denegación de servicio (panic o corrupción de memoria) mediante la creación de sockets SCTP antes de haber finalizado todos los pasos. A NULL pointer dereference flaw was found in the SCTP implementation. A local user could use this flaw to cause a denial of service on the system by triggering a kernel panic when creating multiple sockets in parallel while the system did not have the SCTP module loaded. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8e2d61e0aed2b7c4ecb35844fe07e0b2b762dee4 http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00005.html http://patchwork.ozlabs.org/patch/515996 http://www.debian.org/security/2015/dsa-3372 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.2.3 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http:&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-665: Improper Initialization •
CVSS: 6.9EPSS: 0%CPEs: 1EXPL: 1CVE-2015-7613 – kernel: Unauthorized access to IPC objects with SysV shm
https://notcve.org/view.php?id=CVE-2015-7613
Race condition in the IPC object implementation in the Linux kernel through 4.2.3 allows local users to gain privileges by triggering an ipc_addid call that leads to uid and gid comparisons against uninitialized data, related to msg.c, shm.c, and util.c. Condición de carrera en la implementación del objeto IPC en el kernel de Linux hasta la versión 4.2.3 permite a usuarios locales obtener privilegios desencadenando una llamada a ipc_addid que conduce a comparaciones de uid y gid contra datos no inicializados, relacionada con msg.c, shm.c y util.c. A race condition flaw was found in the way the Linux kernel's IPC subsystem initialized certain fields in an IPC object structure that were later used for permission checking before inserting the object into a globally visible list. A local, unprivileged user could potentially use this flaw to elevate their privileges on the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b9a532277938798b53178d5a66af6e2915cb27cf http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00029.html http://lists.opensuse.org • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-732: Incorrect Permission Assignment for Critical Resource •
