Ben Hawkes discovered that the Linux kernel did not correctly validate memory ranges on 64bit kernels when allocating memory on behalf of 32bit system calls. On a 64bit system, a local attacker could perform malicious multicast getsockopt calls to gain root privileges.
(CVE-2010-3081)

Ben Hawkes discovered that the Linux kernel did not correctly filter registers on 64bit kernels when performing 32bit system calls. On a 64bit system, a local attacker could manipulate 32bit system calls to gain root privileges. (Ubuntu 6.06 LTS and 8.04 LTS were not affected.) (CVE-2010-3301).
