The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6 allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure. La función xc2028_set_config en drivers/media/tuners/tuner-xc2028.c en el kernel de Linux en versiones anteriores a 4.6 permite a usuarios locales obtener privilegios o provocar una denegación de servicio (uso después de liberación de memoria) mediante vectores que implican la omisión del nombre de firmware de una determinada estructura de datos. The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6 allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8dfbcc4351a0b6d2f2d77f367552f48ffefafe18 http://source.android.com/security/bulletin/2016-11-01.html http://www.securityfocus.com/bid/94201 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2019:1170 https://access.redhat.com/errata/RHSA-2019:1190 https://github.com/torvalds/linux/commit/8dfbcc4351a0b6d2f2d77f367552f48ffefafe18 https://usn&# • CWE-416: Use After Free •

The assoc_array_insert_into_terminal_node function in lib/assoc_array.c in the Linux kernel before 4.5.3 does not check whether a slot is a leaf, which allows local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and out-of-bounds read) via an application that uses associative-array data structures, as demonstrated by the keyutils test suite.

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."

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') •
