CVE-2017-7542 – kernel: Integer overflow in ip6_find_1stfragopt() causes infinite loop
https://notcve.org/view.php?id=CVE-2017-7542
The ip6_find_1stfragopt function in net/ipv6/output_core.c in the Linux kernel through 4.12.3 allows local users to cause a denial of service (integer overflow and infinite loop) by leveraging the ability to open a raw socket. La función ip6_find_1stfragopt en el archivo net/ipv6/output_core.c en el kernel de Linux hasta la versión 4.12.3, permite a los usuarios locales causar una denegación de servicio (desbordamiento de enteros y bucle infinito) mediante la explotación de la capacidad de abrir un socket sin procesar. An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6399f1fae4ec29fab5ec76070435555e256ca3a6 http://www.debian.org/security/2017/dsa-3927 http://www.debian.org/security/2017/dsa-3945 http://www.securityfocus.com/bid/99953 https://access.redhat.com/errata/RHSA-2017:2918 https://access.redhat.com/errata/RHSA-2017:2930 https://access.redhat.com/errata/RHSA-2017:2931 https://access.redhat.com/errata/RHSA-2018:0169 https://github.com/torvalds/linux/commit/6399f • CWE-190: Integer Overflow or Wraparound CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2017-11472
https://notcve.org/view.php?id=CVE-2017-11472
The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel before 4.12 does not flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table. La función acpi_ns_terminate() en el archivo drivers/acpi/acpica/nsutils.c en el kernel de Linux anterior a versión 4.12, no limpia la caché operand y causa un volcado de pila del kernel, que permite a los usuarios locales obtener información confidencial de la memoria del kernel y omitir el mecanismo de protección KASLR (en el kernel hasta versión 4.9) por medio de una tabla ACPI creada. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3b2d69114fefa474fca542e51119036dceb4aa6f https://github.com/acpica/acpica/commit/a23325b2e583556eae88ed3f764e457786bf4df6 https://github.com/torvalds/linux/commit/3b2d69114fefa474fca542e51119036dceb4aa6f https://usn.ubuntu.com/3619-1 https://usn.ubuntu.com/3619-2 https://usn.ubuntu.com/3754-1 • CWE-755: Improper Handling of Exceptional Conditions •
CVE-2017-11473 – kernel: Buffer overflow in mp_override_legacy_irq()

Buffer overflow in the mp_override_legacy_irq() function in arch/x86/kernel/acpi/boot.c in the Linux kernel through 3.2 allows local users to gain privileges via a crafted ACPI table. Desbordamiento de búfer en la función mp_override_legacy_irq() en arch/x86/kernel/acpi/boot.c en el kernel de Linux hasta la versión 3.2 permite que los usuarios locales obtengan privilegios mediante una tabla ACPI manipulada.

CVE-2017-11176 – Linux Kernel < 4.11.8 - 'mq_notify: double sock_put()' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2017-11176
The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact. La función mq_notify en el kernel de Linux hasta versión 4.11.9 no se ajusta el puntero sock a NULL al ingresar a la lógica de reintento. Durante un cierre de espacio de usuario de un socket Netlink, permite que los atacantes causen una denegación de servicio (uso de memoria previamente liberada) o posiblemente tengan otro impacto no especificado. A use-after-free flaw was found in the Netlink functionality of the Linux kernel networking subsystem. • https://www.exploit-db.com/exploits/45553 https://github.com/c3r34lk1ll3r/CVE-2017-11176 https://github.com/Sama-Ayman-Mokhtar/CVE-2017-11176 https://github.com/HckEX/CVE-2017-11176 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f991af3daabaecff34684fd51fac80319d1baad1 http://www.debian.org/security/2017/dsa-3927 http://www.debian.org/security/2017/dsa-3945 http://www.securityfocus.com/bid/99919 https://access.redhat.com/errata/RHSA-2017:2918 https: • CWE-416: Use After Free •

The make_response function in drivers/block/xen-blkback/blkback.c in the Linux kernel before 4.11.8 allows guest OS users to obtain sensitive information from host OS (or other guest OS) kernel memory by leveraging the copying of uninitialized padding fields in Xen block-interface response structures, aka XSA-216. La función make_response en el archivo drivers/block/xen-blkback/blkback.c en el kernel de Linux anterior a versión 4.11.8, permite a los usuarios del sistema operativo invitado obtener información confidencial de la memoria del kernel del sistema operativo host (u otro sistema operativo invitado) mediante el aprovechamiento de la copia de campos de relleno no inicializados en estructuras de respuesta de la interfaz del bloque Xen, también se conoce como XSA-216. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=089bc0143f489bd3a4578bdff5f4ca68fb26f341 http://www.debian.org/security/2017/dsa-3920 http://www.debian.org/security/2017/dsa-3927 http://www.debian.org/security/2017/dsa-3945 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.11.8 http://www.securityfocus.com/bid/99162 http://www.securitytracker.com/id/1038720 https://github.com/torvalds/linux/commit/089bc0143f489bd3a4578bdff5f4ca68fb26f341 https://lists. • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
