Red 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.

Red 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.

Mandriva 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.
