Debian Linux Security Advisory 2906-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, information leak or privilege escalation.
f613033ad285f2bace4384c533093667Red Hat Security Advisory 2014-0284-01 - 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 IPv6 implementation handled certain UDP packets when the UDP Fragmentation Offload feature was enabled. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. A flaw was found in the way the Linux kernel's TCP/IP protocol suite implementation handled sending of certain UDP packets over sockets that used the UDP_CORK option when the UDP Fragmentation Offload feature was enabled on the output device. A local, unprivileged user could use this flaw to cause a denial of service or, potentially, escalate their privileges on the system.

da0f77a57b302ce6a8f011ef52c7bef6Red Hat Security Advisory 2014-0163-01 - KVM is a full virtualization solution for Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module built for the standard Red Hat Enterprise Linux kernel. A divide-by-zero flaw was found in the apic_get_tmcct() function in KVM's Local Advanced Programmable Interrupt Controller implementation. A privileged guest user could use this flaw to crash the host. A memory corruption flaw was discovered in the way KVM handled virtual APIC accesses that crossed a page boundary. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system.
ae6730bc03062ad3eb08ed61b2da7cdeMandriva Linux Security Advisory 2014-001 - Multiple vulnerabilities has been found and corrected in the Linux kernel. The KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges or cause a denial of service via a VAPIC synchronization operation involving a page-end address. The apic_get_tmcct function in arch/x86/kvm/lapic.c in the KVM subsystem in the Linux kernel through 3.12.5 allows guest OS users to cause a denial of service via crafted modifications of the TMICT value. Multiple buffer underflows in the XFS implementation in the Linux kernel through 3.12.1 allow local users to cause a denial of service or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for a XFS_IOC_ATTRLIST_BY_HANDLE or XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call with a crafted length value, related to the xfs_attrlist_by_handle function in fs/xfs/xfs_ioctl.c and the xfs_compat_attrlist_by_handle function in fs/xfs/xfs_ioctl32.c. Various other issues have also been addressed.

1af132fdcf7c424f280c901b55f82decRed Hat Security Advisory 2013-1802-01 - The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine hypervisor. It includes everything necessary to run and manage virtual machines: a subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. Upgrade Note: If you upgrade the Red Hat Enterprise Virtualization Hypervisor through the 3.2 Manager administration portal, the Host may appear with the status of "Install Failed". If this happens, place the host into maintenance mode, then activate it again to get the host back to an "Up" state.
