Linux Security The foundation of the Android platform is the Linux kernel. As the base for a mobile computing environment, the Linux kernel provides Android with several key security features, including: A user-based permissions model Process isolation Extensible mechanism for secure IPC The ability to remove unnecessary and potentially insecure parts of the kernel As a multiuser operating system, a fundamental security objective of the Linux kernel is to isolate user resources from one another.
System Partition and Safe Mode The system partition contains Android's kernel as well as the operating system libraries, application runtime, application framework, and applications. Filesystem Permissions In a UNIX-style environment, filesystem permissions ensure that one user cannot alter or read another user's files.
So again, the best kernel you can use is one that someone else supports, and you can turn to for help. Use that support, usually you are already paying for it for the enterprise distributions , and those companies know what they are doing.
But, if you do not want to trust someone else to manage your kernel for you, or you have hardware that a distribution does not support, then you want to run the Latest stable release:. About every three months, the community releases a new stable kernel that contains all of the newest hardware support, the latest performance improvements, as well as the latest bugfixes for all parts of the kernel.
Over the next 3 months, bugfixes that go into the next kernel release to be made are backported into this stable release, so that any users of this kernel are sure to get them as soon as possible. This is usually the kernel that most community distributions use as well, so you can be sure it is tested and has a large audience of users. After 3 months, a new kernel is released and you should move to it to ensure that you stay up to date, as support for this kernel is usually dropped a few weeks after the newer release happens.
If you have new hardware that is purchased after the last LTS release came out, you almost are guaranteed to have to run this kernel in order to have it supported. So for desktops or new servers, this is usually the recommended kernel to be running.
If your hardware relies on a vendors out-of-tree patch in order to make it work properly like almost all embedded devices these days , then the next best kernel to be using is the latest LTS release. That release gets all of the latest kernel fixes that goes into the stable releases where applicable, and lots of users test and use it. Note, no new features and almost no new hardware support is ever added to these kernels, so if you need to use a new device, it is better to use the latest stable release, not this release.
So they stick to this release and upgrade every year instead, which is a fine practice to follow. The downsides of using this release is that you do not get the performance improvements that happen in newer kernels, except when you update to the next LTS kernel, potentially a year in the future. That could be significant for some workloads, so be very aware of this. It showed up when users provided a buffer smaller than skb payload.
Read here about the fix. Impacted versions: Through 3. Another serious vulnerability raised its head for netfilter in the Linux kernel, this time by the incorrect use of a DCCP header pointer. It allows OS users to cause a denial of service attack. The details of the fix can be found here. Impacted versions: Before 2. Hold on tight for this one. View the fix details and the rest of their analysis here.
This can allow hackers to cause a denial of service or even execute arbitrary code via a single crafted MPLS packet. Check out this short and sweet fix to stay secure. See his findings and the fix here. This is the oldest CVE Linux kernel vulnerability to make our list, packing a punch that we still remember from until today. Basically this is a failure to perform the validity check which can cause a memory overflow.
