clear memory. A local attacker with physical access could plug in a
specially crafted block device to read kernel memory, leading to a loss of
privacy. (CVE-2011-1163)

Vasiliy Kulikov discovered that the netfilter code did not check certain
strings copied from userspace. A local attacker with netfilter access could
exploit this to read kernel memory or crash the system, leading to a denial
of service. (CVE-2011-1170, CVE-2011-1171, CVE-2011-1172, CVE-2011-2534)

Vasiliy Kulikov discovered that the Acorn Universal Networking driver did
not correctly initialize memory. A remote attacker could send specially
crafted traffic to read kernel stack memory, leading to a loss of privacy.
(CVE-2011-1173)

Dan Rosenberg discovered that the IRDA subsystem did not correctly check
certain field sizes. If a system was using IRDA, a remote attacker could
send specially crafted traffic to crash the system or gain root privileges.
(CVE-2011-1180)

Julien Tinnes discovered that the kernel did not correctly validate the
signal structure from tkill(). A local attacker could exploit this to send
signals to arbitrary threads, possibly bypassing expected restrictions.
(CVE-2011-1182)

Dan Rosenberg reported errors in the OSS (Open Sound System) MIDI
interface. A local attacker on non-x86 systems might be able to cause a
denial of service. (CVE-2011-1476)
