CVSS: 5.5EPSS: 0%CPEs: 20EXPL: 0CVE-2016-4569 – kernel: Information leak in Linux sound module in timer.c
https://notcve.org/view.php?id=CVE-2016-4569
The snd_timer_user_params function in sound/core/timer.c in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface. La función snd_timer_user_params en sound/core/timer.c en el kernel de Linux hasta la versión 4.6 no inicializa una estructura de datos determinada, lo que permite a usuarios locales obtener información sensible del kernel de memoria de pila a través del uso manipulado de la interfaz ALSA timer. A vulnerability was found in Linux kernel. There is an information leak in file "sound/core/timer.c" of the latest mainline Linux kernel, the stack object “tread” has a total size of 32 bytes. It contains a 8-bytes padding, which is not initialized but sent to user via copy_to_user(), resulting a kernel leak. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=cec8f96e49d9be372fdb0c3836dcf31ec71e457e http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00056.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-665: Improper Initialization •

CVSS: 5.5EPSS: 0%CPEs: 14EXPL: 0CVE-2016-3156 – kernel: ipv4: denial of service when destroying a network interface
https://notcve.org/view.php?id=CVE-2016-3156
The IPv4 implementation in the Linux kernel before 4.5.2 mishandles destruction of device objects, which allows guest OS users to cause a denial of service (host OS networking outage) by arranging for a large number of IP addresses. La implementación IPv4 en el kernel de Linux en versiones anteriores a 4.5.2 no maneja adecuadamente la destrucción de objetos de dispositivo, lo que permite a usuarios del SO invitado provocar una denegación de servicio (corte de la red del sistema operativo anfitrión) disponiendo un gran número de direcciones IP. A security flaw was found in the Linux kernel's networking subsystem that destroying the network interface with huge number of ipv4 addresses assigned keeps "rtnl_lock" spinlock for a very long time (up to hour). This blocks many network-related operations, including creation of new incoming ssh connections. The problem is especially important for containers, as the container owner has enough permissions to trigger this and block a network access on a whole host, outside the container. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=fbd40ea0180a2d328c5adc61414dc8bab9335ce2 http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00059.html http://lists.opensuse.org • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 0CVE-2015-8845 – kernel: incorrect restoration of machine specific registers from userspace
https://notcve.org/view.php?id=CVE-2015-8845
The tm_reclaim_thread function in arch/powerpc/kernel/process.c in the Linux kernel before 4.4.1 on powerpc platforms does not ensure that TM suspend mode exists before proceeding with a tm_reclaim call, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application. La función tm_reclaim_thread en arch/powerpc/kernel/process.c en el Kernel de Linux en versiones anteriores a 4.4.1 sobre plataformas powerpc no asegura que exista el modo TM suspend antes de proceder con una llamada tm_reclaim, lo que permite a usuarios locales provocar una denegación de servicio (excepción TM Bad Thing y pánico) a través de una aplicación manipulada. A flaw was found in the Linux kernel which could cause a kernel panic when restoring machine specific registers on the PowerPC platform. Incorrect transactional memory state registers could inadvertently change the call path on return from userspace and cause the kernel to enter an unknown state and crash. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7f821fc9c77a9b01fe7b1d6e72717b33d8d64142 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00055.html http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-258 • CWE-284: Improper Access Control CWE-772: Missing Release of Resource after Effective Lifetime •
