The do_umount function in fs/namespace.c in the Linux kernel through 3.17 does not require the CAP_SYS_ADMIN capability for do_remount_sb calls that change the root filesystem to read-only, which allows local users to cause a denial of service (loss of writability) by making certain unshare system calls, clearing the / MNT_LOCKED flag, and making an MNT_FORCE umount system call.

The pivot_root implementation in fs/namespace.c in the Linux kernel through 3.17 does not properly interact with certain locations of a chroot directory, which allows local users to cause a denial of service (mount-tree loop) via . (dot) values in both arguments to the pivot_root system call.

The xfs_da3_fixhashpath function in fs/xfs/xfs_da_btree.c in the xfs implementation in the Linux kernel before 3.14.2 does not properly compare btree hash values, which allows local users to cause a denial of service (filesystem corruption, and OOPS or panic) via operations on directories that have hash collisions, as demonstrated by rmdir operations.

net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, does not properly validate auth replies, which allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via crafted data from the IP address of a Ceph Monitor.

net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, does not properly consider the possibility of kmalloc failure, which allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a long unencrypted auth ticket.

Buffer overflow in net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, allows remote attackers to cause a denial of service (memory corruption and panic) or possibly have unspecified other impact via a long unencrypted auth ticket.

The __udf_read_inode function in fs/udf/inode.c in the Linux kernel through 3.16.3 does not restrict the amount of ICB indirection, which allows physically proximate attackers to cause a denial of service (infinite loop or stack consumption) via a UDF filesystem with a crafted inode.

Buffer overflow in the picolcd_raw_event function in devices/hid/hid-picolcd_core.c in the PicoLCD HID device driver in the Linux kernel through 3.16.3, as used in Android on Nexus 7 devices, allows physically proximate attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted device that sends a large report.

Multiple buffer overflows in the command_port_read_callback function in drivers/usb/serial/whiteheat.c in the Whiteheat USB Serial Driver in the Linux kernel before 3.16.2 allow physically proximate attackers to execute arbitrary code or cause a denial of service (memory corruption and system crash) via a crafted device that provides a large amount of (1) EHCI or (2) XHCI data associated with a bulk response.

The report_fixup functions in the HID subsystem in the Linux kernel before 3.16.2 might allow physically proximate attackers to cause a denial of service (out-of-bounds write) via a crafted device that provides a small report descriptor, related to (1) drivers/hid/hid-cherry.c, (2) drivers/hid/hid-kye.c, (3) drivers/hid/hid-lg.c, (4) drivers/hid/hid-monterey.c, (5) drivers/hid/hid-petalynx.c, and (6) drivers/hid/hid-sunplus.c.

Array index error in the logi_dj_raw_event function in drivers/hid/hid-logitech-dj.c in the Linux kernel before 3.16.2 allows physically proximate attackers to execute arbitrary code or cause a denial of service (invalid kfree) via a crafted device that provides a malformed REPORT_TYPE_NOTIF_DEVICE_UNPAIRED value.

Multiple stack-based buffer overflows in the magicmouse_raw_event function in drivers/hid/hid-magicmouse.c in the Magic Mouse HID driver in the Linux kernel through 3.16.3 allow physically proximate attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted device that provides a large amount of (1) EHCI or (2) XHCI data associated with an event.

The sock_setsockopt function in net/core/sock.c in the Linux kernel before 3.5.7 does not ensure that a keepalive action is associated with a stream socket, which allows local users to cause a denial of service (system crash) by leveraging the ability to create a raw socket.

The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel through 3.16.1 allows local users to cause a denial of service (unkillable mount process) via a crafted iso9660 image with a self-referential CL entry.

Stack consumption vulnerability in the parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel through 3.16.1 allows local users to cause a denial of service (uncontrolled recursion, and system crash or reboot) via a crafted iso9660 image with a CL entry referring to a directory entry that has a CL entry.

The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.16.1 miscalculates the number of pages during the handling of a mapping failure, which allows guest OS users to (1) cause a denial of service (host OS memory corruption) or possibly have unspecified other impact by triggering a large gfn value or (2) cause a denial of service (host OS memory consumption) by triggering a small gfn value that leads to permanently pinned pages.

fs/namespace.c in the Linux kernel through 3.16.1 does not properly restrict clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and changing MNT_ATIME_MASK during a remount of a bind mount, which allows local users to gain privileges, interfere with backups and auditing on systems that had atime enabled, or cause a denial of service (excessive filesystem updating) on systems that had atime disabled via a "mount -o remount" command within a user namespace.

The sctp_assoc_update function in net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP authentication is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by starting to establish an association between two endpoints immediately after an exchange of INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite direction.

The mountpoint_last function in fs/namei.c in the Linux kernel before 3.15.8 does not properly maintain a certain reference count during attempts to use the umount system call in conjunction with a symlink, which allows local users to cause a denial of service (memory consumption or use-after-free) or possibly have unspecified other impact via the umount program.

arch/s390/kernel/ptrace.c in the Linux kernel before 3.15.8 on the s390 platform does not properly restrict address-space control operations in PTRACE_POKEUSR_AREA requests, which allows local users to obtain read and write access to kernel memory locations, and consequently gain privileges, via a crafted application that makes a ptrace system call.
