https://notcve.org/view.php?id=CVE-2016-4581
fs/pnode.c in the Linux kernel before 4.5.4 does not properly traverse a mount propagation tree in a certain case involving a slave mount, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted series of mount system calls. fs/pnode.c en el kernel de Linux en versiones anteriores a 4.5.4 no cruza adecuadamente la propagación del montaje de árbol en un determinado caso implicando un montaje esclavo, lo que permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULL y OOPS) a través de una serie de llamadas de soporte manipuladas. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5ec0811d30378ae104f250bfc9b3640242d81e3f http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http://www.debian.org/security/2016/dsa-3607 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.5.4 http://www.openwall.com/lists/oss-security/2016/05/11/2 http://www.oracle.com/ • CWE-476: NULL Pointer Dereference •
CVSS: 7.8EPSS: 0%CPEs: 18EXPL: 0CVE-2016-4913 – kernel: Information leak when handling NM entries containing NUL
https://notcve.org/view.php?id=CVE-2016-4913
The get_rock_ridge_filename function in fs/isofs/rock.c in the Linux kernel before 4.5.5 mishandles NM (aka alternate name) entries containing \0 characters, which allows local users to obtain sensitive information from kernel memory or possibly have unspecified other impact via a crafted isofs filesystem. La función get_rock_ridge_filename en fs/isofs/rock.c en el kernel de Linux en versiones anteriores a 4.5.5 no maneja correctamente entradas NM (también conocidas como alternate name) que contienen caracteres \0, lo que permite a usuarios locales obtener información sensible del kernel de memoria o posiblemente tener otro impacto no especificado a través de un sistema de archivo isofs manipulado. A vulnerability was found in the Linux kernel. Payloads of NM entries are not supposed to contain NUL. When such entry is processed, only the part prior to the first NUL goes into the concatenation (i.e. the directory entry name being encoded by a bunch of NM entries). • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=99d825822eade8d827a1817357cbf3f889a552d6 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://www.debian.org/security/2016/dsa-3607 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.5.5 http://www.openwall.com/lists/oss-security/2016/05/18/3 http://www.openwall.com/lists/oss-security/2016/05/18/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

sound/core/timer.c in the Linux kernel through 4.6 does not initialize certain r1 data structures, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions. sound/core/timer.c en el kernel de Linux hasta la versión 4.6 no inicializa determinadas estructuras de datos r1, 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, relacionado con las funciones (1) snd_timer_user_ccallback y (2) snd_timer_user_tinterrupt. 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 “r1” has a total size of 32 bytes.

Use-after-free vulnerability in mm/percpu.c in the Linux kernel through 4.6 allows local users to cause a denial of service (BUG) or possibly have unspecified other impact via crafted use of the mmap and bpf system calls. Vulnerabilidad de uso después de liberación de memoria en el kernel de Linux hasta la versión 4.6 permite a usuarios locales provocar una denegación de servicio (BUG) o posiblemente tener otro impacto no especificado a través del uso manipulado de llamadas de sistema mmap y bpf. Use after free vulnerability was found in percpu using previously allocated memory in bpf. First __alloc_percpu_gfp() is called, then the memory is freed with free_percpu() which triggers async pcpu_balance_work and then pcpu_extend_area_map could use a chunk after it has been freed. • http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http://www.openwall.com/lists/oss-security/2016/05/12/6 http://www.securityfocus.com/bid/90625 http://www.ubuntu.com/usn/USN-3053-1 http://www.ubuntu.com/usn/USN-3054-1 http://www.ubuntu.com/usn/USN-3055-1 http://www.ubuntu.com/usn/USN-3056-1 http://www.ubuntu.com/usn/USN-3057-1 https://bugzilla.redhat.com/show_bug.cgi?id=1335889 https:& • CWE-416: Use After Free •
