Use-after-free vulnerability in the ffs_user_copy_worker function in drivers/usb/gadget/function/f_fs.c in the Linux kernel before 4.5.3 allows local users to gain privileges by accessing an I/O data structure after a certain callback call. Vulnerabilidad de uso después de liberación de memoria en la función ffs_user_copy_worker en drivers/usb/gadget/function/f_fs.c en el kernel de Linux en versiones anteriores a 4.5.3 permite a usuarios locales obtener privilegios accediendo a una estructura de datos I/O despues de cierta devolución de llamada. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=38740a5b87d53ceb89eb2c970150f6e94e00373a http://source.android.com/security/bulletin/2016-11-01.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.5.3 http://www.securityfocus.com/bid/94197 https://github.com/torvalds/linux/commit/38740a5b87d53ceb89eb2c970150f6e94e00373a • CWE-416: Use After Free •

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 •

Race condition in the environ_read function in fs/proc/base.c in the Linux kernel before 4.5.4 allows local users to obtain sensitive information from kernel memory by reading a /proc/*/environ file during a process-setup time interval in which environment-variable copying is incomplete. La condición de carrera en la función environ_read en fs / proc / base.c en el kernel de Linux antes de 4.5.4 permite a usuarios locales obtener información sensible de la memoria del kernel leyendo un archivo / proc / * / environ durante un intervalo de tiempo de configuración del proceso cuya copia de variabilidad de entorno es incompleta. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8148a73c9901a8794a50f950083c00ccf97d43b3 http://source.android.com/security/bulletin/2016-11-01.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.5.4 http://www.securityfocus.com/bid/94138 http://www.ubuntu.com/usn/USN-3159-1 http://www.ubuntu.com/usn/USN-3159-2 https://bugzilla.kernel.org/show_bug.cgi?id=116461 https://forums.grsecurity.net/viewtopic.php?f=3&t=4363 https://gith • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

Race condition in mm/gup.c in the Linux kernel 2.x through 4.x before 4.8.3 allows local users to gain privileges by leveraging incorrect handling of a copy-on-write (COW) feature to write to a read-only memory mapping, as exploited in the wild in October 2016, aka "Dirty COW." La condición de carrera en mm / gup.c en el kernel de Linux 2.x a 4.x antes de 4.8.3 permite a los usuarios locales obtener privilegios aprovechando el manejo incorrecto de una función copy-on-write (COW) para escribir en un read- only la cartografía de la memoria, como explotados en la naturaleza en octubre de 2016, vulnerabilidad también conocida como "Dirty COW". A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system. Race condition in mm/gup.c in the Linux kernel allows local users to escalate privileges. • https://github.com/dirtycow/dirtycow.github.io https://www.exploit-db.com/exploits/40611 https://www.exploit-db.com/exploits/40838 https://www.exploit-db.com/exploits/40616 https://www.exploit-db.com/exploits/40839 https://www.exploit-db.com/exploits/40847 https://github.com/timwr/CVE-2016-5195 https://github.com/gbonacini/CVE-2016-5195 https://github.com/whu-enjoy/CVE-2016-5195 https://github.com/jas502n/CVE-2016-5195 https://github.com/arttnba3/CVE-2016- • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
