[Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-3035-2 --- # USN-3035-2: Linux kernel (Raspberry Pi 2) vulnerability Publication date 14 July 2016 Overview The system could be made to crash under certain conditions. Releases [15.10](https://ubuntu.com/security/notices?release=wily) --- Open side navigation ## Packages * [linux-raspi2](https://ubuntu.com/security/cves?package=linux-raspi2) - Linux kernel for Raspberry Pi 2 ## Details Jan Stancek discovered that the Linux kernel's memory manager did not properly handle moving pages mapped by the asynchronous I/O (AIO) ring buffer to the other nodes. A local attacker could use this to cause a denial of service (system crash). ## Update instructions After a standard system update you need to reboot your computer to make all the necessary changes. [Learn more about how to get the fixes.](https://ubuntu.com/security/cves/about#security) ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well. The problem can be corrected by updating your system to the following package versions: | Ubuntu Release | Package Version | | --- | --- | | 15.10 wily | [linux-image-4.2.0-1034-raspi2](https://launchpad.net/ubuntu/+source/linux-raspi2) –  [4.2.0-1034.44](https://launchpad.net/ubuntu/+source/linux-raspi2/4.2.0-1034.44) | | | --- ### Reduce your security exposure Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
