Use-after-free vulnerability in fs/crypto/ in the Linux kernel before 4.10.7 allows local users to cause a denial of service (NULL pointer dereference) or possibly gain privileges by revoking keyring keys being used for ext4, f2fs, or ubifs encryption, causing cryptographic transform objects to be freed prematurely. Vulnerabilidad de uso después de liberación de memoria en fs/crypto/ en el kernel de Linux en versiones anteriores a 4.10.7 permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULL) o posiblemente obtener privilegios revocando el llavero de claves utilizado para cifrado ext4, f2fs o ubifs, provocando que los objetos de transformación criptográfica sean liberados prematuramente. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1b53cf9815bb4744958d41f3795d5d5a1d365e2d http://www.securityfocus.com/bid/97308 https://github.com/torvalds/linux/commit/1b53cf9815bb4744958d41f3795d5d5a1d365e2d https://source.android.com/security/bulletin/2017-10-01 https://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.10.7 • CWE-416: Use After Free CWE-476: NULL Pointer Dereference •

The vmw_gb_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.7 does not validate certain levels data, which allows local users to cause a denial of service (system hang) via a crafted ioctl call for a /dev/dri/renderD* device. La función vmw_gb_surface_define_ioctl en drivers/gpu/drm/vmwgfx/vmwgfx_surface.c en el kernel de Linux hasta la versión4.10.7 no valida ciertos niveles de datos, lo que permite a usuarios locales provocar una denegación de servicio (colgar sistema) a través de una llamada al archivo ioctl manipulado para un dispositivo /dev/dri/renderD*. • http://marc.info/?l=linux-kernel&m=149086968410117&w=2 http://www.debian.org/security/2017/dsa-3927 http://www.debian.org/security/2017/dsa-3945 http://www.securityfocus.com/bid/97257 https://bugzilla.redhat.com/show_bug.cgi?id=1437431 https://lists.freedesktop.org/archives/dri-devel/2017-March/137429.html • CWE-20: Improper Input Validation •
CVSS: 7.8EPSS: 0%CPEs: 9EXPL: 4CVE-2017-7308 – Linux 4.8.0 < 4.8.0-46 - AF_PACKET packet_set_ring Privilege Escalation
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 •

https://notcve.org/view.php?id=CVE-2017-7294
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 •
