CVSS: 7.8EPSS: 0%CPEs: 17EXPL: 0CVE-2016-4470 – kernel: Uninitialized variable in request_key handling causes kernel crash in error handling path
https://notcve.org/view.php?id=CVE-2016-4470
The key_reject_and_link function in security/keys/key.c in the Linux kernel through 4.6.3 does not ensure that a certain data structure is initialized, which allows local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command. La función key_reject_and_link en security/keys/key.c en el kernel de Linux hasta la versión 4.6.3 no asegura que cierta estructura de datos esté inicializada, lo que permite a usuarios locales provocar una denegación de servicio (caída del sistema) a través de vectores involucrando un comando keyctl request2 manipulado. A flaw was found in the Linux kernel's keyring handling code: the key_reject_and_link() function could be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free condition on the system, potentially allowing for privilege escalation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=38327424b40bcebe2de92d07312c89360ac9229a http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00009.html http://lists.opensuse.org • CWE-253: Incorrect Check of Function Return Value •

The rds_inc_info_copy function in net/rds/recv.c in the Linux kernel through 4.6.3 does not initialize a certain structure member, which allows remote attackers to obtain sensitive information from kernel stack memory by reading an RDS message. La función rds_inc_info_copy en net/rds/recv.c en el kernel de Linux hasta la versión 4.6.3 no inicializa un cierto miembro de estructura, lo que permite a atacantes remotos obtener información sensible de la memoria de pila del kernel leyendo un mensaje RDS. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4116def2337991b39919f3b448326e21c40e0dbb 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-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-2016-5829 – kernel: Heap buffer overflow in hiddev driver
https://notcve.org/view.php?id=CVE-2016-5829
Multiple heap-based buffer overflows in the hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux kernel through 4.6.3 allow local users to cause a denial of service or possibly have unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2) HIDIOCSUSAGES ioctl call. Múltiples desbordamientos de buffer basado en memoria dinámica en la función hiddev_ioctl_usage en drivers/hid/usbhid/hiddev.c en el kernel de Linux hasta la versión 4.6.3 permiten a usuarios locales provocar una denegación de servicio o tener posiblemente otro impacto no especificado a través de una llamada (1) HIDIOCGUSAGES o (2) HIDIOCSUSAGES ioctl manipulada. A heap-based buffer overflow vulnerability was found in the Linux kernel's hiddev driver. This flaw could allow a local attacker to corrupt kernel memory, possible privilege escalation or crashing the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=93a2001bdfd5376c3dc2158653034c20392d15c5 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/opensuse-security-announce/2016-08/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00048.html http://lists.opensuse.org • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
CVSS: 8.1EPSS: 0%CPEs: 22EXPL: 1CVE-2016-1583 – Linux Kernel - 'ecryptfs' '/proc/$pid/environ' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2016-1583
The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling. La función ecryptfs_privileged_open en fs/ecryptfs/kthread.c en el kernel de Linux en versiones anteriores a 4.6.3 permite a usuarios locales obtener privilegios o provocar una denegación de servicio (consumo de memoria de pila) a través de vectores involucrados con llamadas mmap manipuladas para nombres de ruta /proc, que conduce a una página de error recursiva manipulada. It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/environ. An unprivileged, local user could potentially use this flaw to escalate their privileges on the system. There is a stack overflow in Linux via ecryptfs and /proc/$pid/environ. • https://www.exploit-db.com/exploits/39992 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2f36db71009304b3f0b95afacd8eba1f9f046b87 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f5364c150aa645b3d7daa21b5c0b9feaa1c9cd6d http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opens • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •
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 •
