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.

The Linux kernel was updated to fix security issues and bugs :

Security issues fixed: CVE-2014-4699: The Linux kernel on Intel processors did not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allowed local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls.

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

CVE-2014-4171: mm/shmem.c in the Linux kernel did not properly implement the interaction between range notification and hole punching, which allowed 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.

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

CVE-2014-0100: Race condition in the inet_frag_intern function in net/ipv4/inet_fragment.c in the Linux kernel allowed remote attackers to cause a denial of service (use-after-free error) or possibly have unspecified other impact via a large series of fragmented ICMP Echo Request packets to a system with a heavy CPU load.

CVE-2014-4656: Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel allowed local users to cause a denial of service by leveraging /dev/snd/controlCX access, related to (1) index values in the snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function.

CVE-2014-4655: The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel did not properly maintain the user_ctl_count value, which allowed local users to cause a denial of service (integer overflow and limit bypass) by leveraging /dev/snd/controlCX access for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls.

CVE-2014-4654: The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel did not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allowed local users to remove kernel controls and cause a denial of service (use-after-free and system crash) by leveraging /dev/snd/controlCX access for an ioctl call.

CVE-2014-4653: sound/core/control.c in the ALSA control implementation in the Linux kernel did not ensure possession of a read/write lock, which allowed local users to cause a denial of service (use-after-free) and obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access.

CVE-2014-4652: Race condition in the tlv handler functionality in the snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA control implementation in the Linux kernel allowed local users to obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access.

CVE-2014-4014: The capabilities implementation in the Linux kernel did not properly consider that namespaces are inapplicable to inodes, which allowed local users to bypass intended chmod restrictions by first creating a user namespace, as demonstrated by setting the setgid bit on a file with group ownership of root.

CVE-2014-2309: The ip6_route_add function in net/ipv6/route.c in the Linux kernel did not properly count the addition of routes, which allowed remote attackers to cause a denial of service (memory consumption) via a flood of ICMPv6 Router Advertisement packets.

CVE-2014-3917: kernel/auditsc.c in the Linux kernel, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allowed local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number.

CVE-2014-0131: Use-after-free vulnerability in the skb_segment function in net/core/skbuff.c in the Linux kernel allowed attackers to obtain sensitive information from kernel memory by leveraging the absence of a certain orphaning operation.

Updated kernel packages that fix two security issues and several bugs are now available for Red Hat Enterprise Linux 6.

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.

* A flaw was found in the way the Linux kernel's SCTP implementation validated INIT chunks when performing Address Configuration Change (ASCONF). A remote attacker could use this flaw to crash the system by sending a specially crafted SCTP packet to trigger a NULL pointer dereference on the system. (CVE-2014-7841, Important)

* An integer overflow flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled user controls. A local, privileged user could use this flaw to crash the system. (CVE-2014-4656, Moderate)

The CVE-2014-7841 issue was discovered by Liu Wei of Red Hat.

This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section.

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.
