Details

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.)
