Red Hat Security Advisory 2013-0741-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A race condition was found in the way the Linux kernel's ptrace implementation handled PTRACE_SETREGS requests when the debuggee was woken due to a SIGKILL signal instead of being stopped. A local, unprivileged user could use this flaw to escalate their privileges.

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 1476-1 - Andy Adamson discovered a flaw in the Linux kernel's NFSv4 implementation. A remote NFS server (attacker) could exploit this flaw to cause a denial of service. 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. Schacher Raindel discovered a flaw in the Linux kernel's memory handling when hugetlb is enabled. An unprivileged local attacker could exploit this flaw to cause a denial of service and potentially gain higher privileges. Various other issues were also addressed.
