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 •

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 •

The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not initialize a certain integer variable, which allows local users to obtain sensitive information from kernel stack memory by triggering failure of a get_user_ex call. El macro __get_user_asm_ex en arch/x86/include/asm/uaccess.h en el kernel Linux en versiones anteriores a 4.7.5 no inicia ciertas variables de entero, lo que permite a usuarios locales obtener información sensible de la memoria basado en pila del kernel desencadenando un fallo de la llamada get_user_ex. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1c109fabbd51863475cd12ac206bdd249aee35af http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.7.5 http://www.openwall.com/lists/oss-security/2016/11/04/4 http://www.securityfocus.com/bid/94144 https://bugzilla.redhat.com/show_bug.cgi?id=1391908 https://github.com/torvalds/linux/commit/1c109fabbd51863475cd12ac206bdd249aee35af • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The mpi_powm function in lib/mpi/mpi-pow.c in the Linux kernel through 4.8.11 does not ensure that memory is allocated for limb data, which allows local users to cause a denial of service (stack memory corruption and panic) via an add_key system call for an RSA key with a zero exponent. La función mpi_powm en lib/mpi/mpi-pow.c en el kernel Linux hasta la versión 4.8.11 no se asegura que la memoria esté alojada para datos limb, lo que permite a usuarios locales provocar una denegación de servicio (corrupción de memoria de pila y pánico) a través de una llamada de sistema add_key para una llave RSA con un componente cero. A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f5527fffff3f002b0a6b376163613b82f69de073 http://seclists.org/fulldisclosure/2016/Nov/76 http://www.openwall.com/lists/oss-security/2016/11/24/8 http://www.securityfocus.com/bid/94532 http://www.securitytracker.com/id/1037968 https://access.redhat.com/errata/RHSA-2017:0931 https://access.redhat.com/errata/RHSA-2017:0932 https://access.redhat.com/errata/RHSA-2017:0933 https://access.redhat.com/errata/RHSA- • CWE-20: Improper Input Validation CWE-399: Resource Management Errors CWE-476: NULL Pointer Dereference •

crypto/algif_skcipher.c in the Linux kernel before 4.4.2 does not verify that a setkey operation has been performed on an AF_ALG socket before an accept system call is processed, which allows local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted application that does not supply a key, related to the lrw_crypt function in crypto/lrw.c. crypto/algif_skcipher.c en el kernel Linux en versiones anteriores a 4.4.2 no verifica que una operación setkey haya sido llevada a cabo en un enchufe AF_ALG antes de que una llamada de sistema aceptada sea procesada, lo que permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULO y caída de sistema) a través de una aplicación manipulada que no aporta una llave, relacionado con la función lrw_crypt en crypto/lrw.c. The lrw_crypt() function in 'crypto/lrw.c' in the Linux kernel before 4.5 allows local users to cause a system crash and a denial of service by the NULL pointer dereference via accept(2) system call for AF_ALG socket without calling setkey() first to set a cipher key. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=dd504589577d8e8e70f51f997ad487a4cb6c026f http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.4.2 http://www.openwall.com/lists/oss-security/2016/11/04/3 http://www.securityfocus.com/bid/94217 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://access.redhat.com/errata/RHSA-2017:2437 https://access.redhat.com/errata/RHSA-2017:2444 https:// • CWE-476: NULL Pointer Dereference •
