https://notcve.org/view.php?id=CVE-2017-7187
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.

CVSS: 7.8EPSS: 0%CPEs: 11EXPL: 0CVE-2017-7184 – Linux Kernel XFRM Out-Of-Bounds Access Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2017-7184
The xfrm_replay_verify_len function in net/xfrm/xfrm_user.c in the Linux kernel through 4.10.6 does not validate certain size data after an XFRM_MSG_NEWAE update, which allows local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) by leveraging the CAP_NET_ADMIN capability, as demonstrated during a Pwn2Own competition at CanSecWest 2017 for the Ubuntu 16.10 linux-image-* package 4.8.0.41.52. La función xfrm_replay_verify_len en net/xfrm/xfrm_user.c en el kernel de Linux hasta la versión 4.10.6 no valida ciertos datos de tamaño después de una actualización XFRM_MSG_NEWAE, lo que permite a usuarios locales obtener privilegios de root o provocar una denegación de servicio (acceso fuera de límites basado en memoria dinámica) aprovechando la capacidad CAP_NET_ADMIN, como se demostró durante una competición Pwn2Own en CanSecWest 2017 para el paquete Ubuntu 16.10 linux-image-* 4.8.0.41.52. Out-of-bounds kernel heap access vulnerability was found in xfrm, kernel's IP framework for transforming packets. An error dealing with netlink messages from an unprivileged user leads to arbitrary read/write and privilege escalation. This vulnerability allows local attackers to execute arbitrary code on vulnerable installations of the Linux Kernel. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=677e806da4d916052585301785d847c3b3e6186a http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f843ee6dd019bcece3e74e76ad9df0155655d0df http://openwall.com/lists/oss-security/2017/03/29/2 http://www.eweek.com/security/ubuntu-linux-falls-on-day-1-of-pwn2own-hacking-competition http://www.securityfocus.com/bid/97018 http://www.securitytracker.com/id/1038166 https://access.redhat.com/errata/RHSA-2017:2918 • CWE-122: Heap-based Buffer Overflow •
