CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 0CVE-2016-5828 – Kernel: powerpc: tm: crash via exec system call on PPC
https://notcve.org/view.php?id=CVE-2016-5828
The start_thread function in arch/powerpc/kernel/process.c in the Linux kernel through 4.6.3 on powerpc platforms mishandles transactional state, which allows local users to cause a denial of service (invalid process state or TM Bad Thing exception, and system crash) or possibly have unspecified other impact by starting and suspending a transaction before an exec system call. La función start_thread en arch/powerpc/kernel/process.c en el kernel de Linux hasta la versión 4.6.3 en plataformas powerpc no maneja adecuadamente el estado transaccional, lo que permite a usuarios locales provocar una denegación de servicio (estado de proceso inválido o excepción TM Bad Thing y caída de sistema) o posiblemente tener otro impacto no especificado iniciando y suspendiendo una transacción antes de una llamada de sistema exec. A vulnerability in the handling of Transactional Memory on powerpc systems was found. An unprivileged local user can crash the kernel by starting a transaction, suspending it, and then calling any of the exec() class system calls. • 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://www.debian.org/security/2016/dsa-3616 http://www.openwall.com/lists/oss-security/2016/06/25/7 http://www.securityfocus.com/bid/91415 http://www.ubuntu.com/usn/USN-3070-1 http://www.ubuntu.com&# • CWE-20: Improper Input Validation •

Race condition in the vop_ioctl function in drivers/misc/mic/vop/vop_vringh.c in the MIC VOP driver in the Linux kernel before 4.6.1 allows local users to obtain sensitive information from kernel memory or cause a denial of service (memory corruption and system crash) by changing a certain header, aka a "double fetch" vulnerability. Condición de carrera en la función vop_ioctl en drivers/misc/mic/vop/vop_vringh.c en el controlador MIC VOP en el kernel de Linux en versiones anteriores a 4.6.1 permite a usuarios locales obtener información sensible desde la memoria del kernel o causar una denegación de servicio (corrupción de memoria y caída del sistema) cambiando cierta cabecera, también conocida como vulnerabilidad "double fetch". • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9bf292bfca94694a721449e3fd752493856710f6 http://www.debian.org/security/2016/dsa-3616 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.6.1 http://www.securityfocus.com/archive/1/538802/30/0/threaded http://www.ubuntu.com/usn/USN-3070-1 http://www.ubuntu.com/usn/USN-3070-2 http://www.ubuntu.com/usn/USN-3070-3 http://www.ubuntu.com/usn/USN-3070-4 http://www.ubuntu.com/u • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The tipc_nl_compat_link_dump function in net/tipc/netlink_compat.c in the Linux kernel through 4.6.3 does not properly copy a certain string, which allows local users to obtain sensitive information from kernel stack memory by reading a Netlink message. La función tipc_nl_compat_link_dump en net/tipc/netlink_compat.c en el kernel de Linux hasta la versión 4.6.3 no copia adecuadamente una cierta cadena, lo que permite a usuarios locales obtener información sensible de la memoria de pila del kernel leyendo un mensaje Netlink. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5d2be1422e02ccd697ccfcd45c85b4a26e6178e2 http://www.debian.org/security/2016/dsa-3607 http://www.openwall.com/lists/oss-security/2016/06/03/4 http://www.securityfocus.com/bid/91334 http://www.ubuntu.com/usn/USN-3049-1 http://www.ubuntu.com/usn/USN-3050-1 http://www.ubuntu.com/usn/USN-3051-1 http://www.ubuntu.com/usn/USN-3052-1 http://www.ubuntu.com/usn/USN-3053-1 http:// • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

arch/x86/kvm/vmx.c in the Linux kernel through 4.6.3 mishandles the APICv on/off state, which allows guest OS users to obtain direct APIC MSR access on the host OS, and consequently cause a denial of service (host OS crash) or possibly execute arbitrary code on the host OS, via x2APIC mode. arch/x86/kvm/vmx.c en el kernel de Linux hasta la versión 4.6.3 no maneja adecuadamente el estado on/off de APICv, lo que permite a usuarios invitados del SO obtener acceso APIC MSR directo en el anfitrión del SO y consecuentemente provocar una denegación de servicio (caída del anfitrión del SO) o posiblemente ejecutar código arbitrario en el anfitrión del SO a través del modo x2APIC. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3ce424e45411cf5a13105e0386b6ecf6eeb4f66f http://www.openwall.com/lists/oss-security/2016/05/20/2 https://bugzilla.redhat.com/show_bug.cgi?id=1337806 https://github.com/torvalds/linux/commit/3ce424e45411cf5a13105e0386b6ecf6eeb4f66f • CWE-264: Permissions, Privileges, and Access Controls •
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 •
