CVE-2016-7917
https://notcve.org/view.php?id=CVE-2016-7917
The nfnetlink_rcv_batch function in net/netfilter/nfnetlink.c in the Linux kernel before 4.5 does not check whether a batch message's length field is large enough, which allows local users to obtain sensitive information from kernel memory or cause a denial of service (infinite loop or out-of-bounds read) by leveraging the CAP_NET_ADMIN capability. La función nfnetlink_rcv_batch en net / netfilter / nfnetlink.c en el kernel de Linux en versiones anteriores a 4.5 no comprueba si el campo de longitud de un mensaje por lotes es lo suficientemente grande, lo que permite a los usuarios locales obtener información sensible de la memoria del kernel o provocar una denegación de servicio (bucle infinito o lectura fuera de rango) aprovechando la capacidad de CAP_NET_ADMIN. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c58d6c93680f28ac58984af61d0a7ebf4319c241 http://source.android.com/security/bulletin/2016-11-01.html http://www.securityfocus.com/bid/94147 https://github.com/torvalds/linux/commit/c58d6c93680f28ac58984af61d0a7ebf4319c241 • CWE-125: Out-of-bounds Read CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2016-7911
https://notcve.org/view.php?id=CVE-2016-7911
Race condition in the get_task_ioprio function in block/ioprio.c in the Linux kernel before 4.6.6 allows local users to gain privileges or cause a denial of service (use-after-free) via a crafted ioprio_get system call. Condición de carrera en la función get_task_ioprio en block/ioprio.c en el kernel de Linux en versiones anteriores a 4.6.6 permite a usuarios locales obtener privilegios o provocar una denegación de servicio (uso posterior a la llamada) mediante una llamada manipulada al sistema ioprio_get. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8ba8682107ee2ca3347354e018865d8e1967c5f4 http://source.android.com/security/bulletin/2016-11-01.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.6.6 http://www.securityfocus.com/bid/94135 https://github.com/torvalds/linux/commit/8ba8682107ee2ca3347354e018865d8e1967c5f4 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVE-2015-8963
https://notcve.org/view.php?id=CVE-2015-8963
Race condition in kernel/events/core.c in the Linux kernel before 4.4 allows local users to gain privileges or cause a denial of service (use-after-free) by leveraging incorrect handling of an swevent data structure during a CPU unplug operation. Condición de carrera en la funcionalidad kernel/events/core.c en el kernel de Linux en versiones anteriores a 4.4 permite a los usuarios locales obtener privilegios o provocar una denegación de servicio al utilizar un manejo incorrecto de una estructura de datos de swevent durante una operación de desenchufado de la CPU. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=12ca6ad2e3a896256f086497a7c7406a547ee373 http://source.android.com/security/bulletin/2016-11-01.html http://www.securityfocus.com/bid/94207 https://github.com/torvalds/linux/commit/12ca6ad2e3a896256f086497a7c7406a547ee373 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVE-2016-7910 – kernel: Use after free in seq file
https://notcve.org/view.php?id=CVE-2016-7910
Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel before 4.7.1 allows local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed. Vulnerabilidad de uso después de liberación de memoria en la función disk_seqf_stop en block/genhd.c en el kernel de Linux en versiones anteriores a 4.7.1 permite a usuarios locales obtener privilegios aprovechando la ejecución de una cierta operación de parada incluso si la operación de arranque correspondiente hubiera fallado. A flaw was found in the Linux kernel's implementation of seq_file where a local attacker could manipulate memory in the put() function pointer. This could lead to memory corruption and possible privileged escalation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=77da160530dd1dc94f6ae15a981f24e5f0021e84 http://source.android.com/security/bulletin/2016-11-01.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.7.1 http://www.securityfocus.com/bid/94135 https://access.redhat.com/errata/RHSA-2017:0892 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://gi • CWE-416: Use After Free •
