  - 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 (bnc#963762).

  - CVE-2016-3672: The arch_pick_mmap_layout function in     arch/x86/mm/mmap.c in the Linux kernel did not properly     randomize the legacy base address, which made it easier     for local users to defeat the intended restrictions on     the ADDR_NO_RANDOMIZE flag, and bypass the ASLR     protection mechanism for a setuid or setgid program, by     disabling stack-consumption resource limits     (bnc#974308).

  - CVE-2016-4569: The snd_timer_user_params function in     sound/core/timer.c in the Linux kernel did not     initialize a certain data structure, which allowed local     users to obtain sensitive information from kernel stack     memory via crafted use of the ALSA timer interface     (bsc#979213).

  - CVE-2016-4578: sound/core/timer.c in the Linux kernel     did not initialize certain r1 data structures, which     allowed local users to obtain sensitive information from     kernel stack memory via crafted use of the ALSA timer     interface, related to the (1) snd_timer_user_ccallback     and (2) snd_timer_user_tinterrupt functions     (bnc#979879).

  - CVE-2016-4805: Use-after-free vulnerability in     drivers/net/ppp/ppp_generic.c in the Linux kernel     allowed local users to cause a denial of service (memory     corruption and system crash, or spinlock) or possibly     have unspecified other impact by removing a network     namespace, related to the ppp_register_net_channel and     ppp_unregister_channel functions (bnc#980371).

  - CVE-2016-4998: The IPT_SO_SET_REPLACE setsockopt     implementation in the netfilter subsystem in the Linux     kernel allowed local users to cause a denial of service     (out-of-bounds read) or possibly obtain sensitive     information from kernel heap memory by leveraging     in-container root access to provide a crafted offset     value that leads to crossing a ruleset blob boundary     (bsc#986365).

  - CVE-2016-5244: The rds_inc_info_copy function in     net/rds/recv.c in the Linux kernel did not initialize a     certain structure member, which allowed remote attackers     to obtain sensitive information from kernel stack memory     by reading an RDS message (bnc#983213).

  - CVE-2016-5828: The start_thread function in     arch/powerpc/kernel/process.c in the Linux kernel on     powerpc platforms mishandled transactional state, which     allowed local users to cause a denial of service     (invalid process state or TM Bad Thing exception, and     system crash) or possibly have unspecified other impact     by starting and suspending a transaction an exec system     call (bsc#986569).

An update for kernel is now available for Red Hat Enterprise Linux 7.

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 the Linux kernel's IPv6 implementation mishandled socket options. A local attacker could abuse concurrent access to the socket options to escalate their privileges, or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call. (CVE-2016-3841, Important)

* Several Moderate and Low impact security issues were found in the Linux kernel. Space precludes documenting each of these issues in this advisory. Refer to the CVE links in the References section for a description of each of these vulnerabilities.
