The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.6 does not validate addition of certain levels data, which allows local users to trigger an integer overflow and out-of-bounds write, and cause a denial of service (system hang or crash) or possibly gain privileges, via a crafted ioctl call for a /dev/dri/renderD* device. La función vmw_surface_define_ioctl en drivers/gpu/drm/vmwgfx/vmwgfx_surface.c en el kernel de Linux hasta la versión 4.10.6 no valida adicción de ciertos niveles de datos, lo que permite a usuarios locales activar un desbordamiento de entero y lectura de fuera de límites, y provocar una denegación de servicio (bloqueo del sistema o caída) o posiblemente ganar privilegios, a través de una llamada ioctl manipulada para un dispositivo /dev/dri/renderD*. An out-of-bounds write vulnerability was found in the Linux kernel's vmw_surface_define_ioctl() function, in the 'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://www.securityfocus.com/bid/97177 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://bugzilla.redhat.com/show_bug.cgi?id=1436798 https://lists.freedesktop.org/archives/dri-devel/2017-March/137094.html https://access.redhat.com/security/cve/CVE-2017-7294 • CWE-20: Improper Input Validation CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

The TCP stack in the Linux kernel through 4.10.6 mishandles the SCM_TIMESTAMPING_OPT_STATS feature, which allows local users to obtain sensitive information from the kernel's internal socket data structures or cause a denial of service (out-of-bounds read) via crafted system calls, related to net/core/skbuff.c and net/socket.c. La pila TCP en el kernel de Linux hasta la versión 4.10.6 no maneja adecuadamente la funcionalidad SCM_TIMESTAMPING_OPT_STATS, lo que permite a usuarios locales obtener información sensible de la estructuras internas de datos del socket del kernel o provocar una denegación de servicio (lectura fuera de límites) a través de llamadas al sistema manipuladas, relacionado con net/core/skbuff.c y net/socket.c. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4ef1b2869447411ad3ef91ad7d4891a83c1a509a http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8605330aac5a5785630aec8f64378a54891937cc http://www.securityfocus.com/bid/97141 https://github.com/torvalds/linux/commit/4ef1b2869447411ad3ef91ad7d4891a83c1a509a https://github.com/torvalds/linux/commit/8605330aac5a5785630aec8f64378a54891937cc https://lkml.org/lkml/2017/3/15/485 https://patchwork.ozlabs.org/patch/740636 https://patchwor • CWE-125: Out-of-bounds Read •

The cp_report_fixup function in drivers/hid/hid-cypress.c in the Linux kernel 3.2 and 4.x before 4.9.4 allows physically proximate attackers to cause a denial of service (integer underflow) or possibly have unspecified other impact via a crafted HID report. La función cp_report_fixup en drivers/hid/hid-cypress.c en el kernel de Linux 3.2 y 4.x en versiones anteriores a 4.9.4 permite a atacantes físicamente próximos provocar una denegación de servicio (desbordamiento inferior de entero) o posiblemente tener otro impacto no especificado a través de un reporte HID manipulado • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1ebb71143758f45dc0fa76e2f48429e13b16d110 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4faec4a2ef5dd481682cc155cb9ea14ba2534b76 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.4 http://www.securityfocus.com/bid/97190 https://github.com/torvalds/linux/commit/1ebb71143758f45dc0fa76e2f48429e13b16d110 •

The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.5 does not check for a zero value of certain levels data, which allows local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device. La función vmw_surface_define_ioctl en drivers/gpu/drm/vmwgfx/vmwgfx_surface.c en el kernel de Linux hasta la versión 4.10.5 no verifica el valor cero de ciertos niveles de datos, lo que permite a los usuarios locales provocar una denegación de servicio (referencia ZERO_SIZE_PTR y GPF y posiblemente pánico) a través de una llamada ioctl manipulada para un dispositivo /dev/dri/renderD*. • http://marc.info/?t=149037004200005&r=1&w=2 http://www.securityfocus.com/bid/97096 https://bugzilla.redhat.com/show_bug.cgi?id=1435719 https://lists.freedesktop.org/archives/dri-devel/2017-March/136814.html • CWE-20: Improper Input Validation •

The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function. La función sg_ioctl en drivers/scsi/sg.c en el kernel de Linux hasta la versión 4.10.4 permite a usuarios locales provocar una denegación de servicio (desbordamiento de búfer basado en pila) o posiblemente tener otro impacto no especificado a través de un gran tamaño de comando en una llamada SG_NEXT_CMD_LEN ioctl, conduciendo a acceso de escritura fuera de límites en la función sg_write.
