CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2016-8646 – kernel: Oops in shash_async_export()
https://notcve.org/view.php?id=CVE-2016-8646
The hash_accept function in crypto/algif_hash.c in the Linux kernel before 4.3.6 allows local users to cause a denial of service (OOPS) by attempting to trigger use of in-kernel hash algorithms for a socket that has received zero bytes of data. La función hash_accept en crypto/algif_hash.c en el kernel Linux en versiones anteriores a 4.3.6 permite a usuarios locales provocar una denegación de servicio (OOPS) intentando desencadenar el uso de algoritmos hash in-kernel para un enchufe que ha recibido cero bytes de datos. A vulnerability was found in the Linux kernel. An unprivileged local user could trigger oops in shash_async_export() by attempting to force the in-kernel hashing algorithms into decrypting an empty data set. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4afa5f9617927453ac04b24b584f6c718dfb4f45 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.3.6 http://www.openwall.com/lists/oss-security/2016/11/15/2 http://www.securityfocus.com/bid/94309 https://access.redhat.com/errata/RHSA-2017:1297 https://access.redhat.com/errata/RHSA-2017:1298 https://access.redhat.com/errata/RHSA-2017:1308 https://bugzilla.redhat.com/show_bug.cgi?id=1388821 https: • CWE-476: NULL Pointer Dereference •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2016-9084 – kernel: Integer overflow when using kzalloc in vfio driver
https://notcve.org/view.php?id=CVE-2016-9084
drivers/vfio/pci/vfio_pci_intrs.c in the Linux kernel through 4.8.11 misuses the kzalloc function, which allows local users to cause a denial of service (integer overflow) or have unspecified other impact by leveraging access to a vfio PCI device file. drivers/vfio/pci/vfio_pci_intrs.c en el kernel Linux hasta la versión 4.8.11 usa de forma incorrecta la función kzalloc, lo que permite a usuarios locales provocar una denegación de servicio (desbordamiento de entero) o tener otro posible impacto no especificado aprovechando el acceso al archivo de dispositivo vfio PCI. The use of a kzalloc with an integer multiplication allowed an integer overflow condition to be reached in vfio_pci_intrs.c. This combined with CVE-2016-9083 may allow an attacker to craft an attack and use unallocated memory, potentially crashing the machine. • 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/93930 https://bugzilla.redhat.com/show_bug.cgi?id=1389259 https://github.com/torvalds/linux/commit/05692d7005a364add85c6e25a6c4447ce08f913a https://patchwork.kernel.org/patch/9373631 https:/&#x • CWE-190: Integer Overflow or Wraparound •

The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel 4.4.22 through 4.4.28 contains extended asm statements that are incompatible with the exception table, which allows local users to obtain root access on non-SMEP platforms via a crafted application. NOTE: this vulnerability exists because of incorrect backporting of the CVE-2016-9178 patch to older kernels. El macro __get_user_asm_ex en arch/x86/include/asm/uaccess.h en el kernel Linux 4.4.22 hasta la versión 4.4.28 contiene declaraciones asm extendidas que son incompatibles con la tabla de excepción, lo que permite a usuarios locales obtener acceso de root en plataformas non-SMEP a través de una aplicación manipulada. NOTA: esta vulnerabilidad existe debido a un incorrecto backporting del parche CVE-2016-9178 en kernels antiguos. • http://www.openwall.com/lists/oss-security/2016/11/07/4 http://www.securityfocus.com/bid/94545 http://www.ubuntu.com/usn/USN-3146-1 http://www.ubuntu.com/usn/USN-3146-2 https://lwn.net/Articles/705220 • CWE-264: Permissions, Privileges, and Access Controls •

The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the relationship between the minimum fragment length and the maximum packet size, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability. La función tipc_msg_build en net/tipc/msg.c en el kernel Linux hasta la versión 4.8.11 no valida la relación entre la longitud mínima de fragmento y el tamaño máximo de paquete, lo que permite a usuarios locales obtener privilegios o provocar una denegación de servicio (desbordamiento de búfer basado en memoria dinámica) aprovechando la capacidad CAP_NET_ADMIN. • http://www.openwall.com/lists/oss-security/2016/11/08/5 http://www.securityfocus.com/bid/94211 https://bugzilla.redhat.com/show_bug.cgi?id=1390832 https://www.mail-archive.com/netdev%40vger.kernel.org/msg133205.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-264: Permissions, Privileges, and Access Controls •
