https://notcve.org/view.php?id=CVE-2015-8543
The networking implementation in the Linux kernel through 4.3.3, as used in Android and other products, does not validate protocol identifiers for certain protocol families, which allows local users to cause a denial of service (NULL function pointer dereference and system crash) or possibly gain privileges by leveraging CLONE_NEWUSER support to execute a crafted SOCK_RAW application. La implementación de redes en el kernel de Linux hasta la versión 4.3.3, tal como se utiliza en Android y otros productos, no valida identificadores de protocolo para ciertas familias de protocolos, lo que permite a usuarios locales provocar una denegación de servicio (referencia a puntero de función NULL y caída de sistema) o posiblemente obtener privilegios mediante el aprovechamiento de soporte CLONE_NEWUSER para ejecutar una aplicación SOCK_RAW manipulada. A NULL pointer dereference flaw was found in the way the Linux kernel's network subsystem handled socket creation with an invalid protocol identifier. A local user could use this flaw to crash the system. • https://github.com/bittorrent3389/CVE-2015-8543_for_SLE12SP1 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=79462ad02e861803b3840cc782248c7359451cd9 http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00094.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00038.html http://rhn.redhat.com/errata/RHSA-2016-0855.html http://rhn.redhat.com/errata/RHSA-2016-2574.html http: • CWE-476: NULL Pointer Dereference •

Race condition in the ldsem_cmpxchg function in drivers/tty/tty_ldsem.c in the Linux kernel before 3.13-rc4-next-20131218 allows local users to cause a denial of service (ldsem_down_read and ldsem_down_write deadlock) by establishing a new tty thread during shutdown of a previous tty thread. Condición de carrera en la función ldsem_cmpxchg en drivers/tty/tty_ldsem.c en el kernel de Linux en versiones anteriores a 3.13-rc4-next-20131218 permite a usuarios locales provocar una denegación de servicio (interbloqueo de ldsem_down_read y ldsem_down_write) estableciendo un nuevo hilo tty durante la desconexión de un hilo tty previo. A flaw was discovered in the way the Linux kernel's TTY subsystem handled the tty shutdown phase. A local, unprivileged user could use this flaw to cause denial of service on the system by holding a reference to the ldisc lock during tty shutdown, causing a deadlock. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=cf872776fc84128bb779ce2b83a37c884c3203ae http://www.openwall.com/lists/oss-security/2015/05/26/1 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.securityfocus.com/bid/74820 https://access.redhat.com/errata/RHSA-2016:1395 https://bugzilla.redhat.com/show_bug.cgi?id=1218879 https://github.com/torvalds/linux/commit/cf872776fc84128bb779ce2b83a37c884c3203ae https://www.kernel.org/pub/linu • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-667: Improper Locking •
CVSS: 5.0EPSS: 3%CPEs: 1EXPL: 0CVE-2015-8215 – kernel: MTU value is not validated in IPv6 stack causing packet loss
https://notcve.org/view.php?id=CVE-2015-8215
net/ipv6/addrconf.c in the IPv6 stack in the Linux kernel before 4.0 does not validate attempted changes to the MTU value, which allows context-dependent attackers to cause a denial of service (packet loss) via a value that is (1) smaller than the minimum compliant value or (2) larger than the MTU of an interface, as demonstrated by a Router Advertisement (RA) message that is not validated by a daemon, a different vulnerability than CVE-2015-0272. NOTE: the scope of CVE-2015-0272 is limited to the NetworkManager product. net/ipv6/addrconf.c en la pila IPv6 en el kernel Linux en versiones anteriores a 4.0 no valida los intentos de cambio del valor MTU, lo que permite a atacantes dependientes del contexto causar una denegación de servicio (pérdida de paquetes) a través de un valor que es (1) menor que el valor mínimo compatible o (2) más grande que la MTU de una interfaz, según lo demostrado por un mensaje Router Advertisement (RA) que no es validado por un demonio, una vulnerabilidad diferente a CVE-2015-0272. NOTA: el alcance de CVE-2015-0272 se limita al producto NetworkManager. It was found that the Linux kernel's IPv6 network stack did not properly validate the value of the MTU variable when it was set. A remote attacker could potentially use this flaw to disrupt a target system's networking (packet loss) by setting an invalid MTU value, for example, via a NetworkManager daemon that is processing router advertisement packets running on the target system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=77751427a1ff25b27d47a4c36b12c3c8667855ac 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/2016-02/msg00013.html http://lists.opensuse.org • CWE-20: Improper Input Validation •
