The Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is enabled, does not properly initialize certain data structures, which allows local users to cause a denial of service (memory corruption and system crash) or possibly gain privileges via a crafted application that uses the UDP_CORK option in a setsockopt system call and sends both short and long packets, related to the ip_ufo_append_data function in net/ipv4/ip_output.c and the ip6_ufo_append_data function in net/ipv6/ip6_output.c.

The skb_flow_dissect function in net/core/flow_dissector.c in the Linux kernel through 3.12 allows remote attackers to cause a denial of service (infinite loop) via a small value in the IHL field of a packet with IPIP encapsulation.

Interpretation conflict in drivers/md/dm-snap-persistent.c in the Linux kernel through 3.11.6 allows remote authenticated users to obtain sensitive information or modify data via a crafted mapping to a snapshot block device.

net/ipv6/ip6_output.c in the Linux kernel through 3.11.4 does not properly determine the need for UDP Fragmentation Offload (UFO) processing of small packets after the UFO queueing of a large packet, which allows remote attackers to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact via network traffic that triggers a large response packet.

Off-by-one error in the get_prng_bytes function in crypto/ansi_cprng.c in the Linux kernel through 3.11.4 makes it easier for context-dependent attackers to defeat cryptographic protection mechanisms via multiple requests for small amounts of data, leading to improper management of the state of the consumed data.

The IPv6 SCTP implementation in net/sctp/ipv6.c in the Linux kernel through 3.11.1 uses data structures and function calls that do not trigger an intended configuration of IPsec encryption, which allows remote attackers to obtain sensitive information by sniffing the network.

Use-after-free vulnerability in drivers/net/tun.c in the Linux kernel through 3.11.1 allows local users to gain privileges by leveraging the CAP_NET_ADMIN capability and providing an invalid tuntap interface name in a TUNSETIFF ioctl call.

The dispatch_discard_io function in drivers/block/xen-blkback/blkback.c in the Xen blkback implementation in the Linux kernel before 3.10.5 allows guest OS users to cause a denial of service (data loss) via filesystem write operations on a read-only disk that supports the (1) BLKIF_OP_DISCARD (aka discard or TRIM) or (2) SCSI UNMAP feature.

drivers/hid/hid-picolcd_core.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_PICOLCD is enabled, allows physically proximate attackers to cause a denial of service (NULL pointer dereference and OOPS) via a crafted device.

Multiple array index errors in drivers/hid/hid-multitouch.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_MULTITOUCH is enabled, allow physically proximate attackers to cause a denial of service (heap memory corruption, or NULL pointer dereference and OOPS) via a crafted device.

drivers/hid/hid-sensor-hub.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_SENSOR_HUB is enabled, allows physically proximate attackers to obtain sensitive information from kernel memory via a crafted device.

drivers/hid/hid-ntrig.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_NTRIG is enabled, allows physically proximate attackers to cause a denial of service (NULL pointer dereference and OOPS) via a crafted device.

drivers/hid/hid-lenovo-tpkbd.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_LENOVO_TPKBD is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device.

drivers/hid/hid-logitech-dj.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_LOGITECH_DJ is enabled, allows physically proximate attackers to cause a denial of service (NULL pointer dereference and OOPS) or obtain sensitive information from kernel memory via a crafted device.

The Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_LOGITECH_FF, CONFIG_LOGIG940_FF, or CONFIG_LOGIWHEELS_FF is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device, related to (1) drivers/hid/hid-lgff.c, (2) drivers/hid/hid-lg3ff.c, and (3) drivers/hid/hid-lg4ff.c.

drivers/hid/hid-pl.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_PANTHERLORD is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device.

drivers/hid/hid-steelseries.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_STEELSERIES is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device.

drivers/hid/hid-sony.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_SONY is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device.

drivers/hid/hid-zpff.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_ZEROPLUS is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device.

Multiple array index errors in drivers/hid/hid-core.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11 allow physically proximate attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a crafted device that provides an invalid Report ID.
