It was discovered that CIFS incorrectly handled authentication. When a user had a CIFS share mounted that required authentication, a local user could mount the same share without knowing the correct password.
(CVE-2011-1585)

It was discovered that the GRE protocol incorrectly handled netns initialization. A remote attacker could send a packet while the ip_gre module was loading, and crash the system, leading to a denial of service. (CVE-2011-1767)

It was discovered that the IP/IP protocol incorrectly handled netns initialization. A remote attacker could send a packet while the ipip module was loading, and crash the system, leading to a denial of service. (CVE-2011-1768)

Vasily Averin discovered that the NFS Lock Manager (NLM) incorrectly handled unlock requests. A local attacker could exploit this to cause a denial of service. (CVE-2011-2491)
