The cgroup offline implementation in the Linux kernel through 4.8.11 mishandles certain drain operations, which allows local users to cause a denial of service (system hang) by leveraging access to a container environment for executing a crafted application, as demonstrated by trinity. La implementación offline cgroup en el kernel Linux hasta la versión 4.8.11 maneja incorrectamente ciertas operaciones drain, lo que permite a usuarios locales provocar una denegación de servicio (colgado de sistema) aprovechando el acceso al contenedor de ambiente para ejecutar una aplicación manipulada, como es demostrado por trinity. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=93362fa47fe98b62e4a34ab408c4a418432e7939 http://www.debian.org/security/2017/dsa-3791 http://www.openwall.com/lists/oss-security/2016/11/05/4 http://www.securityfocus.com/bid/94129 https://bugzilla.redhat.com/show_bug.cgi?id=1392439 https://github.com/torvalds/linux/commit/93362fa47fe98b62e4a34ab408c4a418432e7939 https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbhf03802en_us • CWE-20: Improper Input Validation CWE-399: Resource Management Errors •
CVSS: 6.2EPSS: 0%CPEs: 1EXPL: 0CVE-2016-8630 – kernel: kvm: x86: NULL pointer dereference during instruction decode
https://notcve.org/view.php?id=CVE-2016-8630
The x86_decode_insn function in arch/x86/kvm/emulate.c in the Linux kernel before 4.8.7, when KVM is enabled, allows local users to cause a denial of service (host OS crash) via a certain use of a ModR/M byte in an undefined instruction. La función x86_decode_insn en arch/x86/kvm/emulate.c en el kernel Linux en versiones anteriores a 4.8.7, cuando KVM está habilitado, permite a usuarios locales provocar una denegación de servicio (caída de SO anfitrión ) a través de cierto uso del byte ModR/M en una instrucción no definida. Linux kernel built with the Kernel-based Virtual Machine (CONFIG_KVM) support is vulnerable to a null pointer dereference flaw. It could occur on x86 platform, when emulating an undefined instruction. An attacker could use this flaw to crash the host kernel resulting in DoS. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d9092f52d7e61dd1557f2db2400ddb430e85937e http://rhn.redhat.com/errata/RHSA-2017-0386.html http://rhn.redhat.com/errata/RHSA-2017-0387.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.8.7 http://www.openwall.com/lists/oss-security/2016/11/22/3 http://www.securityfocus.com/bid/94459 https://bugzilla.redhat.com/show_bug.cgi?id=1393350 https://github.com/torvalds/linux/commit/d9092f52d7e61dd15 • CWE-284: Improper Access Control CWE-476: NULL Pointer Dereference •

CVSS: 6.8EPSS: 5%CPEs: 1EXPL: 0CVE-2016-8633 – kernel: Buffer overflow in firewire driver via crafted incoming packets
https://notcve.org/view.php?id=CVE-2016-8633
drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations, allows remote attackers to execute arbitrary code via crafted fragmented packets. drivers/firewire/net.c en el kernel Linux en versiones anteriores a 4.8.7, en ciertas configuraciones de hardware no usuales, permite a atacantes remotos ejecutar un código arbitrario a través de paquetes fragmentados manipulados. A buffer overflow vulnerability due to a lack of input filtering of incoming fragmented datagrams was found in the IP-over-1394 driver [firewire-net] in a fragment handling code in the Linux kernel. The vulnerability exists since firewire supported IPv4, i.e. since version 2.6.31 (year 2009) till version v4.9-rc4. A maliciously formed fragment with a respectively large datagram offset would cause a memcpy() past the datagram buffer, which would cause a system panic or possible arbitrary code execution. The flaw requires [firewire-net] module to be loaded and is remotely exploitable from connected firewire devices, but not over a local network. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=667121ace9dbafb368618dbabcf07901c962ddac http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.8.7 http://www.openwall.com/lists/oss-security/2016/11/06/1 http://www.securityfocus.com/bid/94149 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2019:1170 https://access.redhat.com/errata/RHSA-2019:1190 https:// • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-284: Improper Access Control CWE-787: Out-of-bounds Write •
CVSS: 7.8EPSS: 0%CPEs: 7EXPL: 0CVE-2016-9083 – kernel: State machine confusion bug in vfio driver leading to memory corruption
https://notcve.org/view.php?id=CVE-2016-9083
drivers/vfio/pci/vfio_pci.c in the Linux kernel through 4.8.11 allows local users to bypass integer overflow checks, and cause a denial of service (memory corruption) or have unspecified other impact, by leveraging access to a vfio PCI device file for a VFIO_DEVICE_SET_IRQS ioctl call, aka a "state machine confusion bug." drivers/vfio/pci/vfio_pci.c en el kernel Linux hasta la versión 4.8.11 permite a usuarios locales eludir comprobaciones de desbordamiento de enteros, y provocar una denegación de servicio (corrupción de memoria) o tener otro posible impacto no especificado, aprovechando el acceso al archivo de dispositivo vfio PCI para una llamada ioctl VFIO_DEVICE_SET_IRQS, vulnerabilidad también conocida como "state machine confusion bug". A flaw was discovered in the Linux kernel's implementation of VFIO. An attacker issuing an ioctl can create a situation where memory is corrupted and modify memory outside of the expected area. This may overwrite kernel memory and subvert kernel execution. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=05692d7005a364add85c6e25a6c4447ce08f913a http://rhn.redhat.com/errata/RHSA-2017-0386.html http://rhn.redhat.com/errata/RHSA-2017-0387.html http://www.openwall.com/lists/oss-security/2016/10/26/11 http://www.securityfocus.com/bid/93929 https://bugzilla.redhat.com/show_bug.cgi?id=1389258 https://github.com/torvalds/linux/commit/05692d7005a364add85c6e25a6c4447ce08f913a https://patchwork.kernel.org/patch/9373631 https:/&#x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound CWE-391: Unchecked Error Condition •
