Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel before 4.5.2 allows local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions. Vulnerabilidad de uso después de liberación de memoria en drivers/net/ppp/ppp_generic.c en el kernel de Linux en versiones anteriores a 4.5.2 permite a usuarios locales provocar una denegación de servicio (corrupción de memoria y caída de sistema o spinlock) o posiblemente tener otro impacto no especificado eliminando una red namespace, relacionado con las funciones ppp_register_net_channel y ppp_unregister_channel. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1f461dcdd296eecedaffffc6bae2bfa90bd7eb89 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/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://lists.opensuse.org • CWE-416: Use After Free •
CVE-2016-4486 – Linux Kernel 4.4 - 'rtnetlink' Stack Memory Disclosure
https://notcve.org/view.php?id=CVE-2016-4486
The rtnl_fill_link_ifmap function in net/core/rtnetlink.c in the Linux kernel before 4.5.5 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory by reading a Netlink message. La función rtnl_fill_link_ifmap en net/core/rtnetlink.c en el kernel de Linux en versiones anteriores a 4.5.5 no inicializa una estructura de datos determinada, lo que permite a usuarios locales obtener información sensible del kernel de memoria de pila leyendo un mensaje Netlink. • https://www.exploit-db.com/exploits/46006 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5f8e44741f9f216e33736ea4ec65ca9ac03036e6 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 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-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 •
CVE-2016-4558 – Linux Kernel (Ubuntu 16.04) - Reference Count Overflow Using BPF Maps
https://notcve.org/view.php?id=CVE-2016-4558
The BPF subsystem in the Linux kernel before 4.5.5 mishandles reference counts, which allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted application on (1) a system with more than 32 Gb of memory, related to the program reference count or (2) a 1 Tb system, related to the map reference count. El subsistema BPF en el kernel de Linux en versiones anteriores a 4.5.5 no maneja correctamente las cuentas de referencia, lo que permite a usuarios locales provocar una denegación de servicio (uso después de liberación de memoria) o posiblemente tener otro impacto no especificado a través de una aplicación manipulada en (1) un sistema con más de 32 GB de memoria, relacionado con el programa de cuentas de referencia o (2) un sistema de 1 Tb, relacionado con el mapa de cuentas de referencia. • https://www.exploit-db.com/exploits/39773 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=92117d8443bc5afacc8d5ba82e541946310f106e http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.5.5 http://www.openwall.com/lists/oss-security/2016/05/06/4 http://www.ubuntu.com/usn/USN-3005-1 http://www.ubuntu.com/usn/USN-3006-1 http://www.ubuntu.com/usn/USN-3007-1 https://bugzilla.redhat.com/show_bug.cgi?id=1334303 https://github.com •
