CVE-2016-2550
https://notcve.org/view.php?id=CVE-2016-2550
The Linux kernel before 4.5 allows local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by leveraging incorrect tracking of descriptor ownership and sending each descriptor over a UNIX socket before closing it. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-4312. El kernel de Linux en versiones anteriores a 4.5 permite a usuarios locales eludir los límites del archivo descriptor y causar una denegación de servicio (consumo de memoria) mediante el aprovechamiento del incorrecto seguimiento de la propiedad del descriptor y enviando cada descriptor a través de un socket UNIX antes de cerrarlo. NOTA: esta vulnerabilidad existe debido a una solución incorrecta para CVE-2013-4312. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=415e3d3e90ce9e18727e8843ae343eda5a58fad6 http://www.debian.org/security/2016/dsa-3503 http://www.openwall.com/lists/oss-security/2016/02/23/2 http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.ubuntu.com/usn/USN-2946-1 http://www.ubuntu.com/usn/USN-2946-2 http://www.ubuntu.com/usn/USN-2947-1 http://www.ubuntu.com/usn/USN-2947-2 http://www.ubuntu.com/ • CWE-399: Resource Management Errors •
CVE-2015-8816
https://notcve.org/view.php?id=CVE-2015-8816
The hub_activate function in drivers/usb/core/hub.c in the Linux kernel before 4.3.5 does not properly maintain a hub-interface data structure, which allows physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device. La función hub_activate en drivers/usb/core/hub.c en el Kernel de Linux en versiones anteriores a 4.3.5 no mantiene correctamente una estructura de datos hub-interface, lo que permite a atacantes físicamente próximos provocar una denegación de servicio (acceso a memoria no válido y caída de sistema) o posiblemente tener otro impacto no especificado desenchufando un dispositivo hub USB. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e50293ef9775c5f1cf3fcc093037dd6a8c5684ea http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00005.html http://lists.opensuse.org •
CVE-2016-2384 – Linux Kernel 3.x (Ubuntu 14.04 / Mint 17.3 / Fedora 22) - Double-free usb-midi SMEP Privilege Escalation

Double free vulnerability in the snd_usbmidi_create function in sound/usb/midi.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (panic) or possibly have unspecified other impact via vectors involving an invalid USB descriptor. Vulnerabilidad de liberación doble en la función snd_usbmidi_create en sound/usb/midi.c en el kernel de Linux en versiones anteriores a 4.5 permite a atacantes físicamente próximos causar una denegación de servicio (pánico) o posiblemente tener otro impacto no especificado a través de vectores que implican un descriptor USB inválido. A flaw was found in the USB-MIDI Linux kernel driver: a double-free error could be triggered for the 'umidi' object. An attacker with physical access to the system could use this flaw to escalate their privileges. • https://www.exploit-db.com/exploits/41999 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=07d86ca93db7e5cdf4743564d98292042ec21af7 http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00094.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2016 • CWE-416: Use After Free •
CVE-2015-8812 – kernel: CXGB3: Logic bug in return code handling prematurely frees key structures causing Use after free or kernel panic.
https://notcve.org/view.php?id=CVE-2015-8812
drivers/infiniband/hw/cxgb3/iwch_cm.c in the Linux kernel before 4.5 does not properly identify error conditions, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via crafted packets. drivers/infiniband/hw/cxgb3/iwch_cm.c en el Kernel de Linux en versiones anteriores a 4.5 no identifica correctamente condiciones de error, lo que permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (uso después de liberación de memoria) a través de paquetes manipulados. A use-after-free flaw was found in the CXGB3 kernel driver when the network was considered to be congested. The kernel incorrectly misinterpreted the congestion as an error condition and incorrectly freed or cleaned up the socket buffer (skb). When the device then sent the skb's queued data, these structures were referenced. A local attacker could use this flaw to panic the system (denial of service) or, with a local account, escalate their privileges. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=67f1aee6f45059fd6b0f5b0ecb2c97ad0451f6b3 http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00094.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00026.html http://lists.opensuse.org • CWE-416: Use After Free •
