Please Install the Updated Packages.

These packages contain the Linux kernel. Security fixes: * A race condition in the way asynchronous I/O and fallocate() interacted when using ext4 could allow a local, unprivileged user to obtain random data from a deleted file. (CVE-2012-4508, Important) * A flaw in the way the Xen hypervisor implementation range checked guest provided addresses in the XENMEM_exchange hypercall could allow a malicious, para-virtualized guest administrator to crash the hypervisor or, potentially, escalate their privileges, allowing them to execute arbitrary code at the hypervisor level. (CVE-2012-5513, Important) * A flaw in the Reliable Datagram Sockets (RDS) protocol implementation could allow a local, unprivileged user to cause a denial of service. (CVE-2012-2372, Moderate) * A race condition in the way access to inet-&gt opt ip_options was synchronized in the Linux kernel's TCP/IP protocol suite implementation. Depending on the network facing applications running on the system, a remote attacker could possibly trigger this flaw to cause a denial of service. A local, unprivileged user could use this flaw to cause a denial of service regardless of the applications the system runs. (CVE-2012-3552, Moderate) Bug fixes: * Previously, the interrupt handlers of the qla2xxx driver could clear pending interrupts right after the IRQ lines were attached during system start-up. Consequently, the kernel could miss the interrupt that reported completion of the link initialization, and the qla2xxx driver then failed to detect all attached LUNs. With this update, the qla2xxx driver has been modified to no longer clear interrupt bits after attaching the IRQ lines. ... Description truncated, for more information please check the Reference URL
