Ubuntu Security Notice 1774-1 - Andrew Cooper of Citrix reported a Xen stack corruption in the Linux kernel. An unprivileged user in a 32bit PVOPS guest can cause the guest kernel to crash, or operate erroneously. A failure to validate input was discovered in the Linux kernel's Xen netback (network backend) driver. A user in a guest OS may exploit this flaw to cause a denial of service to the guest OS and other guest domains. Various other issues were also addressed.

Red Hat Security Advisory 2013-0496-02 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A race condition was found in the way asynchronous I/O and fallocate() interacted when using the ext4 file system. A local, unprivileged user could use this flaw to expose random data from an extent whose data blocks have not yet been written, and thus contain data from a deleted file.

Ubuntu Security Notice 1720-1 - It was discovered that hypervkvpd, which is distributed in the Linux kernel, was not correctly validating the origin on Netlink messages. An untrusted local user can cause a denial of service of Linux guests in Hyper-V virtualization environments. Dmitry Monakhov reported a race condition flaw the Linux ext4 filesystem that can expose stale data. An unprivileged user could exploit this flaw to cause an information leak. Various other issues were also addressed.
