"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service, information
leaks or data corruption.

  - CVE-2015-1805
    Red Hat discovered that the pipe iovec read and write
    implementations may iterate over the iovec twice but
    will modify the iovec such that the second iteration
    accesses the wrong memory. A local user could use this
    flaw to crash the system or possibly for privilege
    escalation. This may also result in data corruption and
    information leaks in pipes between non-malicious
    processes.

  - CVE-2015-3636
    Wen Xu and wushi of KeenTeam discovered that users
    allowed to create ping sockets can use them to crash the
    system and, on 32-bit architectures, for privilege
    escalation. However, by default, no users on a Debian
    system have access to ping sockets.

  - CVE-2015-4167
    Carl Henrik Lunde discovered that the UDF implementation
    is missing a necessary length checks. A local user that
    can mount devices could use this flaw to crash the
    system."

"It was discovered that the Linux kernel did not properly enforce
rlimits for file descriptors sent over UNIX domain sockets. A local
attacker could use this to cause a denial of service. (CVE-2013-4312)

Ralf Spenneberg discovered that the Aiptek Tablet USB device driver in
the Linux kernel did not properly sanity check the endpoints reported
by the device. An attacker with physical access could cause a denial
of service (system crash). (CVE-2015-7515)

Ralf Spenneberg discovered that the USB driver for Clie devices in the
Linux kernel did not properly sanity check the endpoints reported by
the device. An attacker with physical access could cause a denial of
service (system crash). (CVE-2015-7566)

Ralf Spenneberg discovered that the usbvision driver in the Linux
kernel did not properly sanity check the interfaces and endpoints
reported by the device. An attacker with physical access could cause a
denial of service (system crash). (CVE-2015-7833)

It was discovered that a race condition existed when handling
heartbeat- timeout events in the SCTP implementation of the Linux
kernel. A remote attacker could use this to cause a denial of service.
(CVE-2015-8767)

Venkatesh Pottem discovered a use-after-free vulnerability in the
Linux kernel's CXGB3 driver. A local attacker could use this to cause
a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2015-8812)

It was discovered that a race condition existed in the ioctl handler
for the TTY driver in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash) or expose sensitive
information. (CVE-2016-0723)

It was discovered that the Linux kernel did not keep accurate track of
pipe buffer details when error conditions occurred, due to an
incomplete fix for CVE-2015-1805. A local attacker could use this to
cause a denial of service (system crash) or possibly execute arbitrary
code with administrative privileges. (CVE-2016-0774)

Zach Riggle discovered that the Linux kernel's list poison feature did
not take into account the mmap_min_addr value. A local attacker could
use this to bypass the kernel's poison-pointer protection mechanism
while attempting to exploit an existing kernel vulnerability.
(CVE-2016-0821)

Andy Lutomirski discovered a race condition in the Linux kernel's
translation lookaside buffer (TLB) handling of flush events. A local
attacker could use this to cause a denial of service or possibly leak
sensitive information. (CVE-2016-2069)

Dmitry Vyukov discovered that the Advanced Linux Sound Architecture
(ALSA) framework did not verify that a FIFO was attached to a client
before attempting to clear it. A local attacker could use this to
cause a denial of service (system crash). (CVE-2016-2543)

Dmitry Vyukov discovered that a race condition existed in the Advanced
Linux Sound Architecture (ALSA) framework between timer setup and
closing of the client, resulting in a use-after-free. A local attacker
could use this to cause a denial of service. (CVE-2016-2544)

Dmitry Vyukov discovered a race condition in the timer handling
implementation of the Advanced Linux Sound Architecture (ALSA)
framework, resulting in a use-after-free. A local attacker could use
this to cause a denial of service (system crash). (CVE-2016-2545)

Dmitry Vyukov discovered race conditions in the Advanced Linux Sound
Architecture (ALSA) framework's timer ioctls leading to a
use-after-free. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code.
(CVE-2016-2546)

Dmitry Vyukov discovered that the Advanced Linux Sound Architecture
(ALSA) framework's handling of high resolution timers did not properly
manage its data structures. A local attacker could use this to cause a
denial of service (system hang or crash) or possibly execute arbitrary
code. (CVE-2016-2547, CVE-2016-2548)

Dmitry Vyukov discovered that the Advanced Linux Sound Architecture
(ALSA) framework's handling of high resolution timers could lead to a
deadlock condition. A local attacker could use this to cause a denial
of service (system hang). (CVE-2016-2549)

Ralf Spenneberg discovered that the USB driver for Treo devices in the
Linux kernel did not properly sanity check the endpoints reported by
the device. An attacker with physical access could cause a denial of
service (system crash). (CVE-2016-2782)

It was discovered that the Linux kernel did not enforce limits on the
amount of data allocated to buffer pipes. A local attacker could use
this to cause a denial of service (resource exhaustion).

"Updated kernel packages that fix multiple security issues and several
bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Important
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

* It was found that the Linux kernel's implementation of vectored pipe
read and write functionality did not take into account the I/O vectors
that were already processed when retrying after a failed atomic access
operation, potentially resulting in memory corruption due to an I/O
vector array overrun. A local, unprivileged user could use this flaw
to crash the system or, potentially, escalate their privileges on the
system. (CVE-2015-1805, Important)

* A race condition flaw was found in the way the Linux kernel keys
management subsystem performed key garbage collection. A local
attacker could attempt accessing a key while it was being garbage
collected, which would cause the system to crash. (CVE-2014-9529,
Moderate)

* A flaw was found in the way the Linux kernel's 32-bit emulation
implementation handled forking or closing of a task with an 'int80'
entry. A local user could potentially use this flaw to escalate their
privileges on the system. (CVE-2015-2830, Low)

* It was found that the Linux kernel's ISO file system implementation
did not correctly limit the traversal of Rock Ridge extension
Continuation Entries (CE). An attacker with physical access to the
system could use this flaw to trigger an infinite loop in the kernel,
resulting in a denial of service. (CVE-2014-9420, Low)

* An information leak flaw was found in the way the Linux kernel's
ISO9660 file system implementation accessed data on an ISO9660 image
with RockRidge Extension Reference (ER) records. An attacker with
physical access to the system could use this flaw to disclose up to
255 bytes of kernel memory. (CVE-2014-9584, Low)

* A flaw was found in the way the nft_flush_table() function of the
Linux kernel's netfilter tables implementation flushed rules that were
referencing deleted chains. A local user who has the CAP_NET_ADMIN
capability could use this flaw to crash the system. (CVE-2015-1573,
Low)

* An integer overflow flaw was found in the way the Linux kernel
randomized the stack for processes on certain 64-bit architecture
systems, such as x86-64, causing the stack entropy to be reduced by
four. (CVE-2015-1593, Low)

Red Hat would like to thank Carl Henrik Lunde for reporting
CVE-2014-9420 and CVE-2014-9584. The security impact of the
CVE-2015-1805 issue was discovered by Red Hat.

This update also fixes several bugs. Documentation for these changes
is available from the following Knowledgebase article:
https://access.redhat.com/articles/1469163

All kernel users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. The system
must be rebooted for this update to take effect."
