net/netfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces. net/netfilter/xt_osf.c en el kernel de Linux hasta la versión 4.14.4 no requiere la capacidad CAP_NET_ADMIN para operaciones "add_callback" y "remove_callback", lo que permite que usuarios locales omitan las restricciones de acceso establecidas debido a que la estructura de datos xt_osf_fingers se comparte entre todos los espacios de nombres de la red. • http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00007.html http://www.securityfocus.com/bid/102110 https://lkml.org/lkml/2017/12/5/982 https://usn.ubuntu.com/3583-1 https://usn.ubuntu.com/3583-2 https://usn.ubuntu.com/3617-1 https://usn.ubuntu.com/3617-2 https://usn.ubuntu.com/3617-3 https://usn.ubuntu.com/3619-1 https://usn.ubuntu.com/3619-2 https://usn.ubuntu.com/3632-1 https://www.debian.org/security/2017/dsa-4073 • CWE-862: Missing Authorization •

The walk_hugetlb_range function in mm/pagewalk.c in the Linux kernel before 4.14.2 mishandles holes in hugetlb ranges, which allows local users to obtain sensitive information from uninitialized kernel memory via crafted use of the mincore() system call. La función walk_hugetlb_range en mm/pagewalk.c en el kernel de Linux en versiones anteriores a la 4.14.2 gestiona de manera incorrecta los agujeros en los rangos hugetlb, lo que permite que usuarios locales obtengan información sensible de la memoria del kernel no inicializada mediante el uso manipulado de la llamada del sistema mincore(). The walk_hugetlb_range() function in 'mm/pagewalk.c' file in the Linux kernel from v4.0-rc1 through v4.15-rc1 mishandles holes in hugetlb ranges. This allows local users to obtain sensitive information from uninitialized kernel memory via crafted use of the mincore() system call. • https://www.exploit-db.com/exploits/43178 https://www.exploit-db.com/exploits/44304 https://www.exploit-db.com/exploits/44303 https://github.com/jedai47/CVE-2017-16994 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=373c4557d2aa362702c4c2d41288fb1e54990b7c http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.14.2 http://www.securityfocus.com/bid/101969 https://access.redhat.com/errata/RHSA-2018:0502 https://bugs.chromium.org/p/project-zero/i • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2017-2647 – kernel: Null pointer dereference in search_keyring
https://notcve.org/view.php?id=CVE-2017-2647
The KEYS subsystem in the Linux kernel before 3.18 allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) via vectors involving a NULL value for a certain match field, related to the keyring_search_iterator function in keyring.c. El subsistema KEYS en el kernel de Linux en versiones anteriores a 3.18 permite a los usuarios locales obtener privilegios o provocar una denegación de servicio (referencia a puntero NULL y bloqueo del sistema) a través de vectores que implican un valor NULL para un cierto campo de coincidencia, relacionado con la función keyring_search_iterator en keyring.c. A flaw was found that can be triggered in keyring_search_iterator in keyring.c if type->match is NULL. A local user could use this flaw to crash the system or, potentially, escalate their privileges. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c06cfb08b88dfbe13be44a69ae2fdc3a7c902d81 http://www.securityfocus.com/bid/97258 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://access.redhat.com/errata/RHSA-2017:2437 https://access.redhat.com/errata/RHSA-2017:2444 https://bugzilla.redhat.com/show_bug.cgi?id=1428353 https://github.com/torvalds/linux/commit/c06cfb08b88dfbe13be44a69ae2fdc3a7c902d81 https://usn.ubuntu. • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2017-7308
The packet_set_ring function in net/packet/af_packet.c in the Linux kernel through 4.10.6 does not properly validate certain block-size data, which allows local users to cause a denial of service (integer signedness error and out-of-bounds write), or gain privileges (if the CAP_NET_RAW capability is held), via crafted system calls. La función packet_set_ring en el archivo net/packet/af_packet.c en el kernel de Linux hasta versión 4.10.6, no comprueba apropiadamente ciertos datos de tamaño de bloque, lo que permite a los usuarios locales causar una denegación de servicio (error de firma de enteros y escritura fuera de límites), y alcanzar privilegios (si se mantiene la capacidad CAP_NET_RAW), por medio de llamadas de sistema diseñadas. It was found that the packet_set_ring() function of the Linux kernel's networking implementation did not properly validate certain block-size data. A local attacker with CAP_NET_RAW capability could use this flaw to trigger a buffer overflow resulting in a system crash or a privilege escalation. • https://www.exploit-db.com/exploits/44654 https://www.exploit-db.com/exploits/41994 https://www.exploit-db.com/exploits/47168 https://github.com/anldori/CVE-2017-7308 http://www.securityfocus.com/bid/97234 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://access.redhat.com/errata/RHSA-2018:1854 https://googleprojectzero.blogspot.com/2017/05/exploiting-linux-kernel-via-pa • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-681: Incorrect Conversion between Numeric Types CWE-787: Out-of-bounds Write •
