A flaw was discovered in the Linux kernel’s macvtap device driver, which is
used in KVM (Kernel-based Virtual Machine) to create a network bridge
between host and guest. A privleged user in a guest could exploit this flaw
to crash the host, if the vhost_net module is loaded with the
experimental_zcopytx option enabled. (CVE-2012-2119)
An error was discovered in the Linux kernel’s network TUN/TAP device
implementation. A local user with access to the TUN/TAP interface (which is
not available to unprivileged users until granted by a root user) could
exploit this flaw to crash the system or potential gain administrative
privileges. (CVE-2012-2136)
A flaw was found in how the Linux kernel’s KVM (Kernel-based Virtual
Machine) subsystem handled MSI (Message Signaled Interrupts). A local
unprivileged user could exploit this flaw to cause a denial of service or
potentially elevate privileges. (CVE-2012-2137)
A flaw was found in the Linux kernel’s Reliable Datagram Sockets (RDS)
protocol implementation. A local, unprivileged user could use this flaw to
cause a denial of service. (CVE-2012-2372)
Ulrich Obergfell discovered an error in the Linux kernel’s memory
management subsystem on 32 bit PAE systems with more than 4GB of memory
installed. A local unprivileged user could exploit this flaw to crash the
system. (CVE-2012-2373)
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. (CVE-2012-2669)
Dan Rosenberg discovered flaws in the Linux kernel’s NCI (Near Field
Communication Controller Interface). A remote attacker could exploit these
flaws to crash the system or potentially execute privileged code.
(CVE-2012-3364)
A flaw was discovered in the Linux kernel’s epoll system call. An
unprivileged local user could use this flaw to crash the system.
(CVE-2012-3375)
Some errors where discovered in the Linux kernel’s UDF file system, which
is used to mount some CD-ROMs and DVDs. An unprivileged local user could
use these flaws to crash the system. (CVE-2012-3400)
A flaw was discovered in the madvise feature of the Linux kernel’s memory
subsystem. An unprivileged local use could exploit the flaw to cause a
denial of service (crash the system). (CVE-2012-3511)
Denys Fedoryshchenko discovered a flaw in the Linux kernel’s TCP receive
processing for IPv4. A remote attacker could exploit this flaw to cause a
denial of service (kernel resource consumption) via a flood of SYN+FIN TCP
packets. (CVE-2012-6638)
