"An flaw was discovered in the Linux kernel's audit subsystem when
auditing certain syscalls. A local attacker could exploit this flaw to
obtain potentially sensitive single-bit values from kernel memory or
cause a denial of service (OOPS). (CVE-2014-3917)

An information leak was discovered in the rd_mcp backend of the iSCSI
target subsystem in the Linux kernel. A local user could exploit this
flaw to obtain sensitive information from ramdisk_mcp memory by
leveraging access to a SCSI initiator. (CVE-2014-4027)

Sasha Levin reported an issue with the Linux kernel's shared memory
subsystem when used with range notifications and hole punching. A
local user could exploit this flaw to cause a denial of service.
(CVE-2014-4171)

Toralf Forster reported an error in the Linux kernels syscall
auditing on 32 bit x86 platforms. A local user could exploit this flaw
to cause a denial of service (OOPS and system crash). (CVE-2014-4508)

An information leak was discovered in the control implemenation of the
Advanced Linux Sound Architecture (ALSA) subsystem in the Linux
kernel. A local user could exploit this flaw to obtain sensitive
information from kernel memory. (CVE-2014-4652)

A use-after-free flaw was discovered in the Advanced Linux Sound
Architecture (ALSA) control implementation of the Linux kernel. A
local user could exploit this flaw to cause a denial of service
(system crash). (CVE-2014-4653)

A authorization bug was discovered with the snd_ctl_elem_add function
of the Advanced Linux Sound Architecture (ALSA) in the Linux kernel. A
local user could exploit his bug to cause a denial of service (remove
kernel controls). (CVE-2014-4654)

A flaw discovered in how the snd_ctl_elem function of the Advanced
Linux Sound Architecture (ALSA) handled a reference count. A local
user could exploit this flaw to cause a denial of service (integer
overflow and limit bypass). (CVE-2014-4655)

An integer overflow flaw was discovered in the control implementation
of the Advanced Linux Sound Architecture (ALSA). A local user could
exploit this flaw to cause a denial of service (system crash).
(CVE-2014-4656)

An integer underflow flaw was discovered in the Linux kernel's
handling of the backlog value for certain SCTP packets. A remote
attacker could exploit this flaw to cause a denial of service (socket
outage) via a crafted SCTP packet. (CVE-2014-4667)

Jason Gunthorpe reported a flaw with SCTP authentication in the Linux
kernel. A remote attacker could exploit this flaw to cause a denial of
service (NULL pointer dereference and OOPS). (CVE-2014-5077).

"The SUSE Linux Enterprise 11 Service Pack 3 kernel has been updated to
fix various bugs and security issues.

The following security bugs have been fixed :

  - The media_device_enum_entities function in
    drivers/media/media-device.c in the Linux kernel before
    3.14.6 does not initialize a certain data structure,
    which allows local users to obtain sensitive information
    from kernel memory by leveraging /dev/media0 read access
    for a MEDIA_IOC_ENUM_ENTITIES ioctl call. (bnc#882804).
    (CVE-2014-1739)

  - mm/shmem.c in the Linux kernel through 3.15.1 does not
    properly implement the interaction between range
    notification and hole punching, which allows local users
    to cause a denial of service (i_mutex hold) by using the
    mmap system call to access a hole, as demonstrated by
    interfering with intended shmem activity by blocking
    completion of (1) an MADV_REMOVE madvise call or (2) an
    FALLOC_FL_PUNCH_HOLE fallocate call. (bnc#883518).
    (CVE-2014-4171)

  - arch/x86/kernel/entry_32.S in the Linux kernel through
    3.15.1 on 32-bit x86 platforms, when syscall auditing is
    enabled and the sep CPU feature flag is set, allows
    local users to cause a denial of service (OOPS and
    system crash) via an invalid syscall number, as
    demonstrated by number 1000. (bnc#883724).
    (CVE-2014-4508)

  - The sctp_association_free function in
    net/sctp/associola.c in the Linux kernel before 3.15.2
    does not properly manage a certain backlog value, which
    allows remote attackers to cause a denial of service
    (socket outage) via a crafted SCTP packet. (bnc#885422).
    (CVE-2014-4667)

  - The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux
    kernel through 3.15.6 allows local users to gain
    privileges by leveraging data-structure differences
    between an l2tp socket and an inet socket. (bnc#887082).
    (CVE-2014-4943)

  - 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.
    (bnc#889173). (CVE-2014-5077)

  - 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. (bnc#892490).
    (CVE-2014-5471)

  - 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. (bnc#892490).
    (CVE-2014-5472)

  - Race condition in the mac80211 subsystem in the Linux
    kernel before 3.13.7 allows remote attackers to cause a
    denial of service (system crash) via network traffic
    that improperly interacts with the WLAN_STA_PS_STA state
    (aka power-save mode), related to sta_info.c and tx.c.
    (bnc#871797). (CVE-2014-2706)

  - The rd_build_device_space function in
    drivers/target/target_core_rd.c in the Linux kernel
    before 3.14 does not properly initialize a certain data
    structure, which allows local users to obtain sensitive
    information from ramdisk_mcp memory by leveraging access
    to a SCSI initiator. (bnc#882639). (CVE-2014-4027)

  - The futex_requeue function in kernel/futex.c in the
    Linux kernel through 3.14.5 does not ensure that calls
    have two different futex addresses, which allows local
    users to gain privileges via a crafted FUTEX_REQUEUE
    command that facilitates unsafe waiter modification.
    (bnc#880892). (CVE-2014-3153)

  - Avoid infinite loop when processing indirect ICBs
    (bnc#896689) The following non-security bugs have been
    fixed:. (CVE-2014-6410)

  - ACPI / PAD: call schedule() when need_resched() is true.
