https://notcve.org/view.php?id=CVE-2017-5970
The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel through 4.9.9 allows attackers to cause a denial of service (system crash) via (1) an application that makes crafted system calls or possibly (2) IPv4 traffic with invalid IP options. La función ipv4_pktinfo_prepare en net/ipv4/ip_sockglue.c en el kernel de Linux hasta la versión 4.9.9 permite a atacantes provocar una denegación de servicio (caída de sistema) a través de (1) una aplicación que hace llamadas de sistema manipuladas o posiblemente (2) tráfico IPv4 con opciones IP inválidas. A vulnerability was found in the Linux kernel where having malicious IP options present would cause the ipv4_pktinfo_prepare() function to drop/free the dst. This could result in a system crash or possible privilege escalation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=34b2cef20f19c87999fff3da4071e66937db9644 http://www.debian.org/security/2017/dsa-3791 http://www.openwall.com/lists/oss-security/2017/02/12/3 http://www.securityfocus.com/bid/96233 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://access.redhat.com/errata/RHSA-2017:2669 https://bugzilla.redhat.com/show_bug.cgi?id=1421638 https://github.com/torvalds& • CWE-476: NULL Pointer Dereference •

The aio_mount function in fs/aio.c in the Linux kernel before 4.7.7 does not properly restrict execute access, which makes it easier for local users to bypass intended SELinux W^X policy restrictions, and consequently gain privileges, via an io_setup system call. La función aio_mount en fs/aio.c en el kernel de Linux en versiones anteriores a 4.7.7 no restringe adecuadamente el acceso de ejecución, lo que facilita a usuarios locales eludir restricciones de política destinadas SELinux W^X, y consecuentemente obtener privilegios, a través de una llamada de sistema io_setup. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=22f6b4d34fcf039c63a94e7670e0da24f8575a5a http://source.android.com/security/bulletin/2017-02-01.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.7.7 http://www.securityfocus.com/bid/96122 http://www.securitytracker.com/id/1037798 https://github.com/torvalds/linux/commit/22f6b4d34fcf039c63a94e7670e0da24f8575a5a • CWE-264: Permissions, Privileges, and Access Controls •

The vc4_get_bcl function in drivers/gpu/drm/vc4/vc4_gem.c in the VideoCore DRM driver in the Linux kernel before 4.9.7 does not set an errno value upon certain overflow detections, which allows local users to cause a denial of service (incorrect pointer dereference and OOPS) via inconsistent size values in a VC4_SUBMIT_CL ioctl call. La función vc4_get_bcl en drivers/gpc/drm/vc4/vc4_gem.c en el controlador VideoCore DRM en el kernel de Linux en versiones anteriores a 4.9.7 no establece un valor errno sobre ciertas detecciones de desbordamiento, lo que permite a usuarios locales provocar una denegación de servicio (referencia incorrecta al puntero y OOPS) a través de valores de tamaño inconsistentes en una llamada ioctl VC4_SUBMIT_CL. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6b8ac63847bc2f958dd93c09edc941a0118992d9 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.7 http://www.openwall.com/lists/oss-security/2017/01/21/7 http://www.securityfocus.com/bid/95765 https://bugzilla.redhat.com/show_bug.cgi?id=1416437 https://github.com/torvalds/linux/commit/6b8ac63847bc2f958dd93c09edc941a0118992d9 https://lkml.org/lkml/2017/1/17/759 • CWE-388: 7PK - Errors •

The simple_set_acl function in fs/posix_acl.c in the Linux kernel before 4.9.6 preserves the setgid bit during a setxattr call involving a tmpfs filesystem, which allows local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-7097. La función simple_set_acl en fs/posix_acl.c en el kernel de Linux en versiones anteriores a 4.9.6 preserva el bit setgid durante una llamada setxattr que implica un sistema de archivos tmpfs, lo que permite a usuarios locales obtener privilegios de grupo aprovechando la existencia de un programa setgid con restricciones sobre los permisos de ejecución. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2016-7097.
