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

This update fixes the following security issues :

  - Numerous reference count leaks were found in the Linux     kernel's block layer I/O context handling     implementation. This could allow a local, unprivileged     user to cause a denial of service. (CVE-2012-0879,     Moderate)

  - A flaw was found in the Linux kernel's cifs_lookup()     implementation. POSIX open during lookup should only be     supported for regular files. When non-regular files (for     example, a named (FIFO) pipe or other special files) are     opened on lookup, it could cause a denial of service.
    (CVE-2012-1090, Moderate)

  - It was found that the Linux kernel's register set     (regset) common infrastructure implementation did not     check if the required get and set handlers were     initialized. A local, unprivileged user could use this     flaw to cause a denial of service by performing a     register set operation with a ptrace() PTRACE_SETREGSET     or PTRACE_GETREGSET request. (CVE-2012-1097, Moderate)

This update also fixes several bugs and adds various enhancements. The system must be rebooted for this update to take effect.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The regset (aka register set) feature in the Linux kernel before 3.2.10 does not properly handle the     absence of .get and .set methods, which allows local users to cause a denial of service (NULL pointer     dereference) or possibly have unspecified other impact via a (1) PTRACE_GETREGSET or (2) PTRACE_SETREGSET     ptrace call. (CVE-2012-1097)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:1042 advisory.

    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)

    * It was found that the kvm_vm_ioctl_assign_device() function in the KVM     (Kernel-based Virtual Machine) subsystem of a Linux kernel did not check if     the user requesting device assignment was privileged or not. A local,     unprivileged user on the host could assign unused PCI devices, or even     devices that were in use and whose resources were not properly claimed by     the respective drivers, which could result in the host crashing.
    (CVE-2011-4347, Moderate)

    * A flaw was found in the way the Linux kernel's XFS file system     implementation handled on-disk Access Control Lists (ACLs). A local,     unprivileged user could use this flaw to cause a denial of service or     escalate their privileges by mounting a specially-crafted disk.
    (CVE-2012-0038, Moderate)

    * It was found that the Linux kernel's register set (regset) common     infrastructure implementation did not check if the required get and set     handlers were initialized. A local, unprivileged user could use this flaw     to cause a denial of service by performing a register set operation with a     ptrace() PTRACE_SETREGSET or PTRACE_GETREGSET request. (CVE-2012-1097,     Moderate)

    * 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)

    Red Hat would like to thank Chen Haogang for reporting CVE-2012-0044; Sasha     Levin for reporting CVE-2011-4347; Wang Xi for reporting CVE-2012-0038; and     H. Peter Anvin for reporting CVE-2012-1097.

    This update also fixes the following bugs:

    * When a RoCE (RDMA over Converged Ethernet) adapter with active RoCE     communications was taken down suddenly (either by adapter failure or the     intentional shutdown of the interface), the ongoing RoCE communications     could cause the kernel to panic and render the machine unusable. A patch     has been provided to protect the kernel in this situation and to pass an     error up to the application still using the interface after it has been     taken down instead. (BZ#799944)

    * The fix for Red Hat Bugzilla bug 713494, released via RHSA-2011:0928,     introduced a regression. Attempting to change the state of certain     features, such as GRO (Generic Receive Offload) or TSO (TCP segment     offloading), for a 10 Gigabit Ethernet card that is being used in a     virtual LAN (VLAN) resulted in a kernel panic. (BZ#816974)

    * If a new file was created on a Network File System version 4 (NFSv4)     share, the ownership was set to nfsnobody (-2) until it was possible to     upcall to the idmapper. As a consequence, subsequent file system operations     could incorrectly use -2 for the user and group IDs for the given file,     causing certain operations to fail. In reported cases, this issue also     caused Viminfo file is not writable errors for users running Vim with     files on an NFSv4 share. (BZ#820960)

    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.

The SUSE Linux Enterprise 11 SP2 kernel has been updated to 3.0.26, which fixes a lot of bugs and security issues.

The following security issues have been fixed :

  - A locking problem in transparent hugepage support could     be used by local attackers to potentially crash the     host, or via kvm a privileged guest user could crash the     kvm host system. (CVE-2012-1179)

  - A potential hypervisor escape by issuing SG_IO commands     to partitiondevices was fixed by restricting access to     these commands. (CVE-2011-4127)

  - A local attacker could oops the kernel using memory     control groups and eventfds. (CVE-2012-1146)

  - Limit the path length users can build using epoll() to     avoid local attackers consuming lots of kernel CPU time.
    (CVE-2011-1083)

  - The regset common infrastructure assumed that regsets     would always have .get and .set methods, but necessarily     .active methods. Unfortunately people have since written     regsets without .set method, so NULL pointer dereference     attacks were possible. (CVE-2012-1097)

  - Access to the /proc/pid/taskstats file requires root     access to avoid side channel (timing keypresses etc.)     attacks on other users. (CVE-2011-2494)

  - Fixed a oops in jbd/jbd2 that could be caused by     specific filesystem access patterns. (CVE-2011-4086)

  - A malicious NFSv4 server could have caused a oops in the     nfsv4 acl handling. (CVE-2011-4131)
