file system implementation. A local user could exploit this flaw to examine
some of the kernel's heap memory. (CVE-2012-6548)

Mathias Krause discovered an information leak in the Linux kernel's ISO
9660 CDROM file system driver. A local user could exploit this flaw to
examine some of the kernel's heap memory. (CVE-2012-6549)

An integer overflow was discovered in the Direct Rendering Manager (DRM)
subsystem for the i915 video driver in the Linux kernel. A local user could
exploit this flaw to cause a denial of service (crash) or potentially
escalate privileges. (CVE-2013-0913)

Andrew Honig discovered a flaw in guest OS time updates in the Linux
kernel's KVM (Kernel-based Virtual Machine). A privileged guest user could
exploit this flaw to cause a denial of service (crash host system) or
potential escalate privilege to the host kernel level. (CVE-2013-1796)

Andrew Honig discovered a use after free error in guest OS time updates in
the Linux kernel's KVM (Kernel-based Virtual Machine). A privileged guest
user could exploit this flaw to escalate privilege to the host kernel
level. (CVE-2013-1797)

Andrew Honig reported a flaw in the way KVM (Kernel-based Virtual Machine)
emulated the IOAPIC. A privileged guest user could exploit this flaw to
read host memory or cause a denial of service (crash the host).
(CVE-2013-1798)

A format-string bug was discovered in the Linux kernel's ext3 filesystem
driver. A local user could exploit this flaw to possibly escalate
privileges on the system. (CVE-2013-1848)

A buffer overflow was discovered in the Linux Kernel's USB subsystem for
devices reporting the cdc-wdm class. A specially crafted USB device when
plugged-in could cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2013-1860)

A flaw was discovered in the SCTP (stream control transfer protocol)
network protocol's handling of duplicate cookies in the Linux kernel. A
remote attacker could exploit this flaw to cause a denial of service
(system crash) on another remote user querying the SCTP connection.
(CVE-2013-2206)

An information leak in the Linux kernel's dcb netlink interface was
discovered. A local user could obtain sensitive information by examining
kernel stack memory. (CVE-2013-2634)

A kernel stack information leak was discovered in the RTNETLINK component
of the Linux kernel. A local user could read sensitive information from the
kernel stack. (CVE-2013-2635)");
