handled unlock requests. A local attacker could exploit this to cause a
denial of service. (CVE-2011-2491)
Robert Swiecki discovered that mapping extensions were incorrectly handled.
A local attacker could exploit this to crash the system, leading to a
denial of service. (CVE-2011-2496)
It was discovered that the wireless stack incorrectly verified SSID
lengths. A local attacker could exploit this to cause a denial of service
or gain root privileges. (CVE-2011-2517)
Ben Pfaff discovered that Classless Queuing Disciplines (qdiscs) were being
incorrectly handled. A local attacker could exploit this to crash the
system, leading to a denial of service. (CVE-2011-2525)

attacker could exploit this to crash the system, leading to a denial of
service, or gain root privileges. (CVE-2011-4077)
Nick Bowler discovered the kernel GHASH message digest algorithm
incorrectly handled error conditions. A local attacker could exploit this
to cause a kernel oops. (CVE-2011-4081)
A flaw was found in the Journaling Block Device (JBD). A local attacker
able to mount ext3 or ext4 file systems could exploit this to crash the
system, leading to a denial of service. (CVE-2011-4132)
A bug was found in the way headroom check was performed in
udp6_ufo_fragment() function. A remote attacker could use this flaw to
crash the system. (CVE-2011-4326)
