Red Hat Security Advisory 2012-0010-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A malicious CIFS server could send a specially-crafted response to a directory read request that would result in a denial of service or privilege escalation on a system that has a CIFS share mounted. The way fragmented IPv6 UDP datagrams over the bridge with UDP Fragmentation Offload functionality on were handled could allow a remote attacker to cause a denial of service.

Red Hat Security Advisory 2011-1479-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Using PCI passthrough without interrupt remapping support allowed Xen hypervisor guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting. Various other issues were also addressed.

Red Hat Security Advisory 2011-1465-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. IPv6 fragment identification value generation could allow a remote attacker to disrupt a target system's networking, preventing legitimate users from accessing its services. A signedness issue was found in the Linux kernel's CIFS implementation. A malicious CIFS server could send a specially-crafted response to a directory read request that would result in a denial of service or privilege escalation on a system that has a CIFS share mounted.
