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

This update fixes the following security issues :

  - A local, unprivileged user could use an integer overflow     flaw in drm_mode_dirtyfb_ioctl() to cause a denial of     service or escalate their privileges. (CVE-2012-0044,     Important)

  - A buffer overflow flaw was found in the macvtap device     driver, used for creating a bridged network between the     guest and the host in KVM (Kernel-based Virtual Machine)     environments. A privileged guest user in a KVM guest     could use this flaw to crash the host. Note: This issue     only affected hosts that have the vhost_net module     loaded with the experimental_zcopytx module option     enabled (it is not enabled by default), and that also     have macvtap configured for at least one guest.
    (CVE-2012-2119, Important)

  - When a set user ID (setuid) application is executed,     certain personality flags for controlling the     application's behavior are cleared (that is, a     privileged application will not be affected by those     flags). It was found that those flags were not cleared     if the application was made privileged via file system     capabilities. A local, unprivileged user could use this     flaw to change the behavior of such applications,     allowing them to bypass intended restrictions. Note that     for default installations, no application shipped by us     for Scientific Linux is made privileged via file system     capabilities. (CVE-2012-2123, Important)

  - It was found that the data_len parameter of the     sock_alloc_send_pskb() function in the Linux kernel's     networking implementation was not validated before use.
    A privileged guest user in a KVM guest could use this     flaw to crash the host or, possibly, escalate their     privileges on the host. (CVE-2012-2136, Important)

  - A buffer overflow flaw was found in the     setup_routing_entry() function in the KVM subsystem of     the Linux kernel in the way the Message Signaled     Interrupts (MSI) routing entry was handled. A local,     unprivileged user could use this flaw to cause a denial     of service or, possibly, escalate their privileges.
    (CVE-2012-2137, Important)

  - A race condition was found in the Linux kernel's memory     management subsystem in the way pmd_none_or_clear_bad(),     when called with mmap_sem in read mode, and Transparent     Huge Pages (THP) page faults interacted. A privileged     user in a KVM guest with the ballooning functionality     enabled could potentially use this flaw to crash the     host. A local, unprivileged user could use this flaw to     crash the system. (CVE-2012-1179, Moderate)

  - A flaw was found in the way device memory was handled     during guest device removal. Upon successful device     removal, memory used by the device was not properly     unmapped from the corresponding IOMMU or properly     released from the kernel, leading to a memory leak. A     malicious user on a KVM host who has the ability to     assign a device to a guest could use this flaw to crash     the host. (CVE-2012-2121, Moderate)

  - A flaw was found in the Linux kernel's Reliable Datagram     Sockets (RDS) protocol implementation. A local,     unprivileged user could use this flaw to cause a denial     of service. (CVE-2012-2372, Moderate)

  - A race condition was found in the Linux kernel's memory     management subsystem in the way pmd_populate() and     pte_offset_map_lock() interacted on 32-bit x86 systems     with more than 4GB of RAM. A local, unprivileged user     could use this flaw to cause a denial of service.
    (CVE-2012-2373, Moderate)

This update also fixes several bugs.

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

A flaw was discovered in the Linux kernel's macvtap device driver, which is used in KVM (Kernel-based Virtual Machine) to create a network bridge between host and guest. A privleged user in a guest could exploit this flaw to crash the host, if the vhost_net module is loaded with the experimental_zcopytx option enabled. (CVE-2012-2119)

An error was discovered in the Linux kernel's network TUN/TAP device implementation. A local user with access to the TUN/TAP interface (which is not available to unprivileged users until granted by a root user) could exploit this flaw to crash the system or potential gain administrative privileges. (CVE-2012-2136)

A flaw was found in how the Linux kernel's KVM (Kernel-based Virtual Machine) subsystem handled MSI (Message Signaled Interrupts). A local unprivileged user could exploit this flaw to cause a denial of service or potentially elevate privileges. (CVE-2012-2137)

A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2372)

Ulrich Obergfell discovered an error in the Linux kernel's memory management subsystem on 32 bit PAE systems with more than 4GB of memory installed. A local unprivileged user could exploit this flaw to crash the system. (CVE-2012-2373)

Dan Rosenberg discovered flaws in the Linux kernel's NCI (Near Field Communication Controller Interface). A remote attacker could exploit these flaws to crash the system or potentially execute privileged code. (CVE-2012-3364)

A flaw was discovered in the Linux kernel's epoll system call. An unprivileged local user could use this flaw to crash the system.
(CVE-2012-3375)

Some errors where discovered in the Linux kernel's UDF file system, which is used to mount some CD-ROMs and DVDs. An unprivileged local user could use these flaws to crash the system. (CVE-2012-3400)

A flaw was discovered in the madvise feature of the Linux kernel's memory subsystem. An unprivileged local use could exploit the flaw to cause a denial of service (crash the system). (CVE-2012-3511).
