This update for the Linux Kernel 3.12.51-52_31 fixes several issues.
The following security bugs were fixed :

  - CVE-2016-4470: The key_reject_and_link function in     security/keys/key.c in the Linux kernel did not ensure     that a certain data structure is initialized, which     allowed local users to cause a denial of service (system     crash) via vectors involving a crafted keyctl request2     command (bsc#984764).

  - CVE-2016-1583: The ecryptfs_privileged_open function in     fs/ecryptfs/kthread.c in the Linux kernel allowed local     users to gain privileges or cause a denial of service     (stack memory consumption) via vectors involving crafted     mmap calls for /proc pathnames, leading to recursive     pagefault handling (bsc#983144).

  - CVE-2016-4565: The InfiniBand (aka IB) stack in the     Linux kernel incorrectly relied on the write system     call, which allowed local users to cause a denial of     service (kernel memory write operation) or possibly have     unspecified other impact via a uAPI interface     (bsc#980883).

  - CVE-2016-0758: Integer overflow in lib/asn1_decoder.c in     the Linux kernel allowed local users to gain privileges     via crafted ASN.1 data (bsc#980856).

  - CVE-2015-8019: The skb_copy_and_csum_datagram_iovec     function in net/core/datagram.c in the Linux kernel did     not accept a length argument, which allowed local users     to cause a denial of service (memory corruption) or     possibly have unspecified other impact via a write     system call followed by a recvmsg system call     (bsc#979078).

  - CVE-2016-2053: The asn1_ber_decoder function in     lib/asn1_decoder.c in the Linux kernel allowed attackers     to cause a denial of service (panic) via an ASN.1 BER     file that lacks a public key, leading to mishandling by     the public_key_verify_signature function in     crypto/asymmetric_keys/public_key.c (bsc#979074).

  - CVE-2015-8816: The hub_activate function in     drivers/usb/core/hub.c in the Linux kernel did not     properly maintain a hub-interface data structure, which     allowed physically proximate attackers to cause a denial     of service (invalid memory access and system crash) or     possibly have unspecified other impact by unplugging a     USB hub device (bsc#979064).

  - CVE-2016-3134: The netfilter subsystem in the Linux     kernel did not validate certain offset fields, which     allowed local users to gain privileges or cause a denial     of service (heap memory corruption) via an     IPT_SO_SET_REPLACE setsockopt call (bsc#971793).

  - CVE-2013-7446: Use-after-free vulnerability in     net/unix/af_unix.c in the Linux kernel allowed local     users to bypass intended AF_UNIX socket permissions or     cause a denial of service (panic) via crafted epoll_ctl     calls (bsc#973570, bsc#955837).

The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2016-1154:09 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any     Linux operating system.  The kernel handles the basic functions     of the operating system: memory allocation, process allocation, device     input and output, etc.
    Security issues fixed with this release:
    CVE-2016-1583     The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the     Linux kernel before 4.6.3 allows local users to gain privileges or     cause a denial of service (stack memory consumption) via vectors     involving crafted mmap calls for /proc pathnames, leading to recursive     pagefault handling.
    CVE-2016-2143     The fork implementation in the Linux kernel before 4.5 on s390     platforms mishandles the case of four page-table levels, which allows     local users to cause a denial of service (system crash) or possibly     have unspecified other impact via a crafted application, related to     arch/s390/include/asm/mmu_context.h and     arch/s390/include/asm/pgalloc.h.
    Fixed bugs:
    * Use of a multi-threaded workload with high memory mappings sometiems caused a kernel panic, due to a     race condition between the context switch and the pagetable upgrade. This update fixes the switch_mm() by     using the complete asce parameter instead of the asce_bits parameter. As a result, the kernel no longer     panics in the described scenario.
    * When iptables created the Transmission Control Protocol (TCP) reset packet, a kernel crash could occur     due to uninitialized pointer to the TCP header within the Socket Buffer (SKB). This update fixes the     transport header pointer in TCP reset for both IPv4 and IPv6, and the kernel no longer crashes in the     described situation.
    * Previously, when the Enhanced Error Handling (EEH) mechanism did not block the PCI configuration space     access and an error was detected, a kernel panic occurred. This update fixes EEH to fix this problem. As a     result, the kernel no longer panics in the described scenario.
    * When the lockd service failed to start up completely, the notifier blocks were in some cases registered     on a notification chain multiple times, which caused the occurrence of a circular list on the notification     chain. Consequently, a soft lock-up or a kernel oops occurred. With this update, the notifier blocks are     unregistered if lockd fails to start up completely, and the soft lock-ups or the kernel oopses no longer     occur under the described circumstances.
    * When the Fibre Channel over Ethernet (FCoE) was configured, the FCoE MaxFrameSize parameter was     incorrectly restricted to 1452. With this update, the NETIF_F_ALL_FCOE symbol is no longer ignored, which     fixes this bug. MaxFrameSize is now restricted to 2112, which is the correct value.
    * When the fnic driver was installed on Cisco UCS Blade Server, the discs were under certain circumstances     put into the offline state with the following error message: Medium access timeout failure. Offlining     disk!. This update fixes fnic to set the Small Computer System Interface (SCSI) status as DID_ABORT after     a successful abort operation. As a result, the discs are no longer put into the offlined state in the     described situation.

The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3007-1 advisory.

    Justin Yackoski discovered that the Atheros L2 Ethernet Driver in the Linux kernel incorrectly enables     scatter/gather I/O. A remote attacker could use this to obtain potentially sensitive information from     kernel memory. (CVE-2016-2117)

    Jann Horn discovered that eCryptfs improperly attempted to use the mmap() handler of a lower filesystem     that did not implement one, causing a recursive page fault to occur. A local unprivileged attacker could     use to cause a denial of service (system crash) or possibly execute arbitrary code with administrative     privileges. (CVE-2016-1583)

    Multiple race conditions where discovered in the Linux kernel's ext4 file system. A local user could     exploit this flaw to cause a denial of service (disk corruption) by writing to a page that is associated     with a different users file after unsynchronized hole punching and page-fault handling. (CVE-2015-8839)

    Ralf Spenneberg discovered that the Linux kernel's GTCO digitizer USB device driver did not properly     validate endpoint descriptors. An attacker with physical access could use this to cause a denial of     service (system crash). (CVE-2016-2187)

    Vitaly Kuznetsov discovered that the Linux kernel did not properly suppress hugetlbfs support in X86     paravirtualized guests. An attacker in the guest OS could cause a denial of service (guest system crash).
    (CVE-2016-3961)

    Kangjie Lu discovered an information leak in the ANSI/IEEE 802.2 LLC type 2 Support implementations in the     Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel     memory. (CVE-2016-4485)

    Kangjie Lu discovered an information leak in the routing netlink socket interface (rtnetlink)     implementation in the Linux kernel. A local attacker could use this to obtain potentially sensitive     information from kernel memory. (CVE-2016-4486)

    Jann Horn discovered that the extended Berkeley Packet Filter (eBPF) implementation in the Linux kernel     could overflow reference counters on systems with more than 32GB of physical ram and with RLIMIT_MEMLOCK     set to infinite. A local unprivileged attacker could use to create a use-after- free situation, causing a     denial of service (system crash) or possibly gain administrative privileges. (CVE-2016-4558)

    Jann Horn discovered that the InfiniBand interfaces within the Linux kernel could be coerced into     overwriting kernel memory. A local unprivileged attacker could use this to possibly gain administrative     privileges on systems where InifiniBand related kernel modules are loaded. (CVE-2016-4565)

    It was discovered that in some situations the Linux kernel did not handle propagated mounts correctly. A     local unprivileged attacker could use this to cause a denial of service (system crash). (CVE-2016-4581)

An update for kernel is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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

Security Fix(es) :

* It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/ environ. An unprivileged, local user could potentially use this flaw to escalate their privileges on the system.
(CVE-2016-1583, Important)

* It was reported that on s390x, the fork of a process with four page table levels will cause memory corruption with a variety of symptoms.
All processes are created with three level page table and a limit of 4TB for the address space. If the parent process has four page table levels with a limit of 8PB, the function that duplicates the address space will try to copy memory areas outside of the address space limit for the child process. (CVE-2016-2143, Moderate)

Bug Fix(es) :

* Use of a multi-threaded workload with high memory mappings sometiems caused a kernel panic, due to a race condition between the context switch and the pagetable upgrade. This update fixes the switch_mm() by using the complete asce parameter instead of the asce_bits parameter.
As a result, the kernel no longer panics in the described scenario.
(BZ#1377472)

* When iptables created the Transmission Control Protocol (TCP) reset packet, a kernel crash could occur due to uninitialized pointer to the TCP header within the Socket Buffer (SKB). This update fixes the transport header pointer in TCP reset for both IPv4 and IPv6, and the kernel no longer crashes in the described situation.(BZ#1372266)

* Previously, when the Enhanced Error Handling (EEH) mechanism did not block the PCI configuration space access and an error was detected, a kernel panic occurred. This update fixes EEH to fix this problem. As a result, the kernel no longer panics in the described scenario.
(BZ#1379596)

* When the lockd service failed to start up completely, the notifier blocks were in some cases registered on a notification chain multiple times, which caused the occurrence of a circular list on the notification chain. Consequently, a soft lock-up or a kernel oops occurred. With this update, the notifier blocks are unregistered if lockd fails to start up completely, and the soft lock-ups or the kernel oopses no longer occur under the described circumstances.
(BZ#1375637)

* When the Fibre Channel over Ethernet (FCoE) was configured, the FCoE MaxFrameSize parameter was incorrectly restricted to 1452. With this update, the NETIF_F_ALL_FCOE symbol is no longer ignored, which fixes this bug. MaxFrameSize is now restricted to 2112, which is the correct value. (BZ#1381592)

* When the fnic driver was installed on Cisco UCS Blade Server, the discs were under certain circumstances put into the offline state with the following error message: 'Medium access timeout failure. Offlining disk!'. This update fixes fnic to set the Small Computer System Interface (SCSI) status as DID_ABORT after a successful abort operation.

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:2124 advisory.

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

    Security Fix(es):

    * A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write     (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to     gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.
    (CVE-2016-5195, Important)

    * It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack     overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by     mapping /proc/environ. An unprivileged, local user could potentially use this flaw to escalate their     privileges on the system. (CVE-2016-1583, Important)

    Red Hat would like to thank Phil Oester for reporting CVE-2016-5195.

    Bug Fix(es):

    * In some cases, a kernel crash or file system corruption occurred when running journal mode 'ordered'.
    The kernel crash was caused by a null pointer dereference due to a race condition between two journal     functions. The file system corruption occurred due to a race condition between the do_get_write_access()     function and buffer writeout. This update fixes both race conditions. As a result, neither the kernel     crash, nor the file system corruption now occur. (BZ#1067708)

    * Prior to this update, some Global File System 2 (GFS2) files had incorrect time stamp values due to two     problems with handling time stamps of such files. The first problem concerned the atime time stamp, which     ended up with an arbitrary value ahead of the actual value, when a GFS2 file was accessed. The second     problem was related to the mtime and ctime time stamp updates, which got lost when a GFS2 file was written     to from one node and read from or written to from another node. With this update, a set of patches has     been applied that fix these problems. As a result, the time stamps of GFS2 files are now handled     correctly. (BZ#1374861)
