Red Hat Security Advisory 2012-1491-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way Netlink messages without SCM_CREDENTIALS data set were handled. When not explicitly set, the data was sent but with all values set to 0, including the process ID and user ID, causing the Netlink message to appear as if it were sent with root privileges. A local, unprivileged user could use this flaw to send spoofed Netlink messages to an application, possibly resulting in the application performing privileged operations if it relied on SCM_CREDENTIALS data for the authentication of Netlink messages.

Red Hat Security Advisory 2012-1323-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way socket buffers requiring TSO were handled by the sfc driver. If the skb did not fit within the minimum-size of the transmission queue, the network card could repeatedly reset itself. A remote attacker could use this flaw to cause a denial of service.

Red Hat Security Advisory 2012-1304-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. An integer overflow flaw was found in the i915_gem_do_execbuffer() function in the Intel i915 driver in the Linux kernel. A local, unprivileged user could use this flaw to cause a denial of service. This issue only affected 32-bit systems. A memory leak flaw was found in the way the Linux kernel's memory subsystem handled resource clean up in the mmap() failure path when the MAP_HUGETLB flag was set. A local, unprivileged user could use this flaw to cause a denial of service.

Ubuntu Security Notice 1580-1 - Ben Hutchings reported a flaw in the Linux kernel with some network drivers that support TSO (TCP segment offload). A local or peer user could exploit this flaw to to cause a denial of service. Jay Fenlason and Doug Ledford discovered a bug in the Linux kernel implementation of RDS sockets. A local unprivileged user could potentially use this flaw to read privileged information from the kernel. Various other issues were also addressed.
