The icmp6_send function in net/ipv6/icmp.c in the Linux kernel through 4.8.12 omits a certain check of the dst data structure, which allows remote attackers to cause a denial of service (panic) via a fragmented IPv6 packet. La función icmp6_send en net/ipv6/icmp.c en el kernel de Linux hasta la versión 4.8.12 omite una cierta comprobación de la estructura de datos dst, lo que permite a atacantes remotos provocar una denegación de servicio (pánico) a través de un paquete IPv6 fragmentado. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=79dc7e3f1cd323be4c81aa1a94faa1b3ed987fb2 http://www.openwall.com/lists/oss-security/2016/12/08/15 http://www.securityfocus.com/bid/94824 https://github.com/torvalds/linux/commit/79dc7e3f1cd323be4c81aa1a94faa1b3ed987fb2 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2016-8655
Race condition in net/packet/af_packet.c in the Linux kernel through 4.8.12 allows local users to gain privileges or cause a denial of service (use-after-free) by leveraging the CAP_NET_RAW capability to change a socket version, related to the packet_set_ring and packet_setsockopt functions. Condición de carrera en net/packet/af_packet.c en el kernel de Linux hasta la versión 4.8.12 permite a usuarios locales obtener privilegios o provocar una denegación de servicio (uso después de liberación de memoria) aprovechando la capacidad CAP_NET_RAW de cambiar una versión socket, relacionado con las funciones packet_set_ring y packet_setsockopt. A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets implementation in the Linux kernel networking subsystem handled synchronization while creating the TPACKET_V3 ring buffer. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system. • https://www.exploit-db.com/exploits/44696 https://www.exploit-db.com/exploits/40871 https://www.exploit-db.com/exploits/47170 https://github.com/LakshmiDesai/CVE-2016-8655 https://github.com/KosukeShimofuji/CVE-2016-8655 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=84ac7260236a49c79eede91617700174c2c19b0c http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00054.html http://l • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2016-8650
The mpi_powm function in lib/mpi/mpi-pow.c in the Linux kernel through 4.8.11 does not ensure that memory is allocated for limb data, which allows local users to cause a denial of service (stack memory corruption and panic) via an add_key system call for an RSA key with a zero exponent. La función mpi_powm en lib/mpi/mpi-pow.c en el kernel Linux hasta la versión 4.8.11 no se asegura que la memoria esté alojada para datos limb, lo que permite a usuarios locales provocar una denegación de servicio (corrupción de memoria de pila y pánico) a través de una llamada de sistema add_key para una llave RSA con un componente cero. A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f5527fffff3f002b0a6b376163613b82f69de073 http://seclists.org/fulldisclosure/2016/Nov/76 http://www.openwall.com/lists/oss-security/2016/11/24/8 http://www.securityfocus.com/bid/94532 http://www.securitytracker.com/id/1037968 https://access.redhat.com/errata/RHSA-2017:0931 https://access.redhat.com/errata/RHSA-2017:0932 https://access.redhat.com/errata/RHSA-2017:0933 https://access.redhat.com/errata/RHSA- • CWE-20: Improper Input Validation CWE-399: Resource Management Errors CWE-476: NULL Pointer Dereference •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2016-9084 – kernel: Integer overflow when using kzalloc in vfio driver
https://notcve.org/view.php?id=CVE-2016-9084
drivers/vfio/pci/vfio_pci_intrs.c in the Linux kernel through 4.8.11 misuses the kzalloc function, which allows local users to cause a denial of service (integer overflow) or have unspecified other impact by leveraging access to a vfio PCI device file. drivers/vfio/pci/vfio_pci_intrs.c en el kernel Linux hasta la versión 4.8.11 usa de forma incorrecta la función kzalloc, lo que permite a usuarios locales provocar una denegación de servicio (desbordamiento de entero) o tener otro posible impacto no especificado aprovechando el acceso al archivo de dispositivo vfio PCI. The use of a kzalloc with an integer multiplication allowed an integer overflow condition to be reached in vfio_pci_intrs.c. This combined with CVE-2016-9083 may allow an attacker to craft an attack and use unallocated memory, potentially crashing the machine. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=05692d7005a364add85c6e25a6c4447ce08f913a http://rhn.redhat.com/errata/RHSA-2017-0386.html http://rhn.redhat.com/errata/RHSA-2017-0387.html http://www.openwall.com/lists/oss-security/2016/10/26/11 http://www.securityfocus.com/bid/93930 https://bugzilla.redhat.com/show_bug.cgi?id=1389259 https://github.com/torvalds/linux/commit/05692d7005a364add85c6e25a6c4447ce08f913a https://patchwork.kernel.org/patch/9373631 https:/&#x • CWE-190: Integer Overflow or Wraparound •

The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the relationship between the minimum fragment length and the maximum packet size, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability.
