CVE-2016-2384 – Linux Kernel 3.x (Ubuntu 14.04 / Mint 17.3 / Fedora 22) - Double-free usb-midi SMEP Privilege Escalation

https://notcve.org/view.php?id=CVE-2016-2384

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 •

CVE-2015-8830 – kernel: AIO write triggers integer overflow in some protocols

https://notcve.org/view.php?id=CVE-2015-8830

Integer overflow in the aio_setup_single_vector function in fs/aio.c in the Linux kernel 4.0 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. NOTE: this vulnerability exists because of a CVE-2012-6701 regression. Desbordamiento de entero en la función aio_setup_single_vector en fs/aio.c en el kernel de Linux 4.0 permite a usuarios locales provocar una denegación de servicio o posiblemente tener otro impacto no especificado a través de un iovec AIO grande.
