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)

Gael Delalleu, Rafal Wojtczuk, and Brad Spengler discovered that the memory manager did not properly handle when applications grow stacks into adjacent memory regions. A local attacker could exploit this to gain control of certain applications, potentially leading to privilege escalation, as demonstrated in attacks against the X server. (CVE-2010-2240) Kees Cook discovered that under certain situations the ioctl subsystem for DRM did not properly sanitize its arguments. A local attacker could exploit this to read previously freed kernel memory, leading to a loss of privacy. (CVE-2010-2803) Ben Hawkes discovered an integer overflow in the Controller Area Network (CAN) subsystem when setting up frame content and filtering certain messages. An attacker could send specially crafted CAN traffic to crash the system or gain root privileges. (CVE-2010-2959)
