The sock_setsockopt function in net/core/sock.c in the Linux kernel before 3.5 mishandles negative values of sk_sndbuf and sk_rcvbuf, which allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUF or (2) SO_RCVBUF option. La función sock_setsockopt en net/core/sock.c en el kernel de Linux en versiones anteriores a 3.5 no maneja adecuadamente valores negativos de sk_sndbuf y sk_rcvbuf, lo que permite a usuarios locales provocar una denegación de servicio (corrupción de memoria y caída del sistema) o posiblemente tener otro impacto no especificado aprovechando la capacidad CAP_NET_ADMIN para una llamada al sistema setsockopt manipulada con la opción (1) SO_SNDBUF o (2) SO_RCVBUF. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=82981930125abfd39d7c8378a9cfdf5e1be2002b http://www.openwall.com/lists/oss-security/2016/12/03/1 http://www.securityfocus.com/bid/95135 https://bugzilla.redhat.com/show_bug.cgi?id=1402024 https://github.com/torvalds/linux/commit/82981930125abfd39d7c8378a9cfdf5e1be2002b • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2016-9588 – Kernel: kvm: nVMX: uncaught software exceptions in L1 guest leads to DoS
https://notcve.org/view.php?id=CVE-2016-9588
arch/x86/kvm/vmx.c in the Linux kernel through 4.9 mismanages the #BP and #OF exceptions, which allows guest OS users to cause a denial of service (guest OS crash) by declining to handle an exception thrown by an L2 guest. arch/x86/kvm/vmx.c en el kernek de Linux hasta la versión 4.9 no gestiona adecuadamente las excepciones #BP y #OF, lo que permite a usuarios del SO invitados provocar una denegación de servicio (caída del SO invitado) declinando el manejo de una excepción lanzada por un invitado L2. Linux kernel built with the KVM visualization support (CONFIG_KVM), with nested visualization(nVMX) feature enabled(nested=1), is vulnerable to an uncaught exception issue. It could occur if an L2 guest was to throw an exception which is not handled by an L1 guest. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ef85b67385436ddc1998f45f1d6a210f935b3388 http://www.debian.org/security/2017/dsa-3804 http://www.openwall.com/lists/oss-security/2016/12/15/3 http://www.securityfocus.com/bid/94933 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://bugzilla.redhat.com/show_bug.cgi?id=1404924 https://github.com/torvalds/linux/commit/ef85b67385436ddc1998f45f1d6a210f935b3388 https:/&#x • CWE-248: Uncaught Exception CWE-388: 7PK - Errors •

https://notcve.org/view.php?id=CVE-2016-9794
Race condition in the snd_pcm_period_elapsed function in sound/core/pcm_lib.c in the ALSA subsystem in the Linux kernel before 4.7 allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted SNDRV_PCM_TRIGGER_START command. Condición de carrera en la función snd_pcm_period_elapsed en sound/core/pcm_lib.c en el subsistema de ALSA en el kernel de Linux en versiones anteriores a 4.7 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 un comando SNDRV_PCM_TRIGGER_START manipulado. A use-after-free vulnerability was found in ALSA pcm layer, which allows local users to cause a denial of service, memory corruption, or possibly other unspecified impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3aa02cb664c5fb1042958c8d1aa8c35055a2ebc4 http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00057.html http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00062.html http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00072.html http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00075.html http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00081.html http://lists.opensuse.org • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2016-9685 – kernel: Memory leaks in xfs_attr_list.c error paths
https://notcve.org/view.php?id=CVE-2016-9685
Multiple memory leaks in error paths in fs/xfs/xfs_attr_list.c in the Linux kernel before 4.5.1 allow local users to cause a denial of service (memory consumption) via crafted XFS filesystem operations. Múltiples fugas de memoria en rutas de error en fs/xfs/xfs_attr_list.c en el kernel de Linux en versiones anteriores a 4.5.1 permiten a usuarios locales provocar una denegación de servicio (consumo de memoria) a través de operaciones de archivo de sistema XFS manipuladas. A flaw was found in the Linux kernel's implementation of XFS file attributes. Two memory leaks were detected in xfs_attr_shortform_list and xfs_attr3_leaf_list_int when running a docker container backed by xfs/overlay2. A dedicated attacker could possible exhaust all memory and create a denial of service situation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2e83b79b2d6c78bf1b4aa227938a214dcbddc83f http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.5.1 http://www.openwall.com/lists/oss-security/2016/11/30/1 http://www.securityfocus.com/bid/94593 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://access.redhat.com/errata/RHSA-2017:2669 https://bugzilla.redhat.com/show_bug.cgi?id=1396941 https: • CWE-400: Uncontrolled Resource Consumption CWE-772: Missing Release of Resource after Effective Lifetime •
