Multiple vulnerabilities has been found and corrected in the Linux kernel :

Multiple array index errors in drivers/hid/hid-core.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11 allow physically proximate attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a crafted device that provides an invalid Report ID (CVE-2013-2888).

drivers/hid/hid-zpff.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_ZEROPLUS is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device (CVE-2013-2889).

drivers/hid/hid-pl.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_PANTHERLORD is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device (CVE-2013-2892).

The Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_LOGITECH_FF, CONFIG_LOGIG940_FF, or CONFIG_LOGIWHEELS_FF is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device, related to (1) drivers/hid/hid-lgff.c, (2) drivers/hid/hid-lg3ff.c, and (3) drivers/hid/hid-lg4ff.c (CVE-2013-2893).

drivers/hid/hid-logitech-dj.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_LOGITECH_DJ is enabled, allows physically proximate attackers to cause a denial of service (NULL pointer dereference and OOPS) or obtain sensitive information from kernel memory via a crafted device (CVE-2013-2895).

drivers/hid/hid-ntrig.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_NTRIG is enabled, allows physically proximate attackers to cause a denial of service (NULL pointer dereference and OOPS) via a crafted device (CVE-2013-2896).

Multiple array index errors in drivers/hid/hid-multitouch.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_MULTITOUCH is enabled, allow physically proximate attackers to cause a denial of service (heap memory corruption, or NULL pointer dereference and OOPS) via a crafted device (CVE-2013-2897).

The udp_v6_push_pending_frames function in net/ipv6/udp.c in the IPv6 implementation in the Linux kernel through 3.10.3 makes an incorrect function call for pending data, which allows local users to cause a denial of service (BUG and system crash) via a crafted application that uses the UDP_CORK option in a setsockopt system call (CVE-2013-4162).

The ip6_append_data_mtu function in net/ipv6/ip6_output.c in the IPv6 implementation in the Linux kernel through 3.10.3 does not properly maintain information about whether the IPV6_MTU setsockopt option had been specified, which allows local users to cause a denial of service (BUG and system crash) via a crafted application that uses the UDP_CORK option in a setsockopt system call (CVE-2013-4163).

The validate_event function in arch/arm/kernel/perf_event.c in the Linux kernel before 3.10.8 on the ARM platform allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) by adding a hardware event to an event group led by a software event (CVE-2013-4254

The updated packages provides a solution for these security issues.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-002324 advisory.

    The ip6_append_data_mtu function in net/ipv6/ip6_output.c in the IPv6 implementation in the Linux kernel     through 3.10.3 does not properly maintain information about whether the IPV6_MTU setsockopt option had     been specified, which allows local users to cause a denial of service (BUG and system crash) via a crafted     application that uses the UDP_CORK option in a setsockopt system call.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, information leak or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems :

Updated kernel-rt packages that fix several security issues and multiple bugs are now available for Red Hat Enterprise MRG 2.3.

The Red Hat Security Response Team 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-rt packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issues :

* A heap-based buffer overflow flaw was found in the Linux kernel's iSCSI target subsystem. A remote attacker could use a specially crafted iSCSI request to cause a denial of service on a system or, potentially, escalate their privileges on that system. (CVE-2013-2850, Important)

* A flaw was found in the Linux kernel's Performance Events implementation. On systems with certain Intel processors, a local, unprivileged user could use this flaw to cause a denial of service by leveraging the perf subsystem to write into the reserved bits of the OFFCORE_RSP_0 and OFFCORE_RSP_1 model-specific registers.
(CVE-2013-2146, Moderate)

* An invalid pointer dereference flaw was found in the Linux kernel's TCP/IP protocol suite implementation. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system by using sendmsg() with an IPv6 socket connected to an IPv4 destination. (CVE-2013-2232, Moderate)

* Two flaws were found in the way the Linux kernel's TCP/IP protocol suite implementation handled IPv6 sockets that used the UDP_CORK option. A local, unprivileged user could use these flaws to cause a denial of service. (CVE-2013-4162, CVE-2013-4163, Moderate)

* A flaw was found in the Linux kernel's Chipidea USB driver. A local, unprivileged user could use this flaw to cause a denial of service.
(CVE-2013-2058, Low)

* Information leak flaws in the Linux kernel could allow a privileged, local user to leak kernel memory to user-space. (CVE-2013-2147, CVE-2013-2164, CVE-2013-2234, CVE-2013-2237, Low)

* Information leak flaws in the Linux kernel could allow a local, unprivileged user to leak kernel memory to user-space. (CVE-2013-2141, CVE-2013-2148, Low)

* A format string flaw was found in the Linux kernel's block layer. A privileged, local user could potentially use this flaw to escalate their privileges to kernel level (ring0). (CVE-2013-2851, Low)

* A format string flaw was found in the b43_do_request_fw() function in the Linux kernel's b43 driver implementation. A local user who is able to specify the 'fwpostfix' b43 module parameter could use this flaw to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-2852, Low)

* A NULL pointer dereference flaw was found in the Linux kernel's ftrace and function tracer implementations. A local user who has the CAP_SYS_ADMIN capability could use this flaw to cause a denial of service. (CVE-2013-3301, Low)

Red Hat would like to thank Kees Cook for reporting CVE-2013-2850, CVE-2013-2851, and CVE-2013-2852; and Hannes Frederic Sowa for reporting CVE-2013-4162 and CVE-2013-4163.

This update also fixes the following bugs :

* The following drivers have been updated, fixing a number of bugs:
myri10ge, bna, enic, mlx4, bgmac, bcma, cxgb3, cxgb4, qlcnic, r8169, be2net, e100, e1000, e1000e, igb, ixgbe, brcm80211, cpsw, pch_gbe, bfin_mac, bnx2x, bnx2, cnic, tg3, and sfc. (BZ#974138)

* The realtime kernel was not built with the CONFIG_NET_DROP_WATCH kernel configuration option enabled. As such, attempting to run the dropwatch command resulted in the following error :

Unable to find NET_DM family, dropwatch can't work Cleaning up on socket creation error

With this update, the realtime kernel is built with the CONFIG_NET_DROP_WATCH option, allowing dropwatch to work as expected.
(BZ#979417)
