Details

A flaw was found in the Linux’s kernels ext4 file system when mounted with
a journal. A local, unprivileged user could exploit this flaw to cause a
denial of service. (CVE-2011-4086)

A flaw was found in the Linux kernel’s KVM (Kernel Virtual Machine) virtual
cpu setup. An unprivileged local user could exploit this flaw to crash the
system leading to a denial of service. (CVE-2012-1601)

Steve Grubb reported a flaw with Linux fscaps (file system base
capabilities) when used to increase the permissions of a process. For
application on which fscaps are in use a local attacker can disable address
space randomization to make attacking the process with raised privileges
easier. (CVE-2012-2123)
