Red Hat Security Advisory 2013-1292-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A use-after-free flaw was found in the madvise() system call implementation in the Linux kernel. A local, unprivileged user could use this flaw to cause a denial of service or, potentially, escalate their privileges. A flaw was found in the way the Linux kernel's TCP/IP protocol suite implementation handled IPv6 sockets that used the UDP_CORK option. A local, unprivileged user could use this flaw to cause a denial of service.

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 2012-1426-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A use-after-free flaw was found in the Linux kernel's memory management subsystem in the way quota handling for huge pages was performed. A local, unprivileged user could use this flaw to cause a denial of service or, potentially, escalate their privileges. A use-after-free flaw was found in the madvise() system call implementation in the Linux kernel. A local, unprivileged user could use this flaw to cause a denial of service or, potentially, escalate their privileges.

Ubuntu Security Notice 1577-1 - A flaw was discovered in the Linux kernel's KVM (kernel virtual machine). An administrative user in the guest OS could leverage this flaw to cause a denial of service in the host OS. 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.

Ubuntu Security Notice 1574-1 - A flaw was found in how the Linux kernel passed the replacement session keyring to a child process. An unprivileged local user could exploit this flaw to cause a denial of service (panic).

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.
