Future versions of Android will be more resilient to exploits, thanks to developers' efforts to integrate the latest Linux kernel defenses into the operating system.
Android's security model relies heavily on the Linux kernel that sits at its core. As such, Android developers have always been interested in adding new security features that are intended to prevent potentially malicious code from reaching the kernel, which is the most privileged area of the operating system.
[...] One new configuration option called CONFIG_DEBUG_RODATA segments the kernel memory into multiple sections and limits how much of this memory is writeable and executable. Attackers need writeable and executable memory pages in order to inject malicious code into them via exploits, and then run that code with kernel privileges.
Another config option, called CONFIG_CPU_SW_DOMAIN_PAN, prevents the kernel from directly accessing user space memory, giving attackers even less control over where their exploits can execute code.

Fuckin' Android. The Anti-Linux. Does everything it can to prevent you from getting root.
Shame on google.
Seems to me its not all that hard.
"Getting root" seems to be source of most of the exploits you see in the wild.
Just google "silently root android" to see how common it is for malware to root phones. Combine that with the tendency of every teenager to root their phone for no rational purpose and you have a situation ripe for abuse.
The problem wasn't that Google made it hard, It should be hard. It was that google used that to protect all the spyware and un-removable apps that manufacturers and carriers foist on the user. Lots of people root just to get rid of crap-ware.
That and the fact that fine-grained permissions didn't arrive until something like the 10th or 12th release of android made the phone into a spy platform exploitable by any random app author.
No, you are mistaken. I've always had this sig.

Dick Bathroom-Stall Man said anybody who wants root should have root. For the FREEEEEDOOOOOOOOOMS.

But almost always people do wrong rooting (like using Kingroot) which adds even more spyware (itself, purify...) unless you clean flash the thing...
Root should be accessible for developers easily with adb (pc) but not directly from the device since the apps shouldn't be trusted.
I use root everyday on my device since I have installed several utilies like: AfWall+ (frontend for iptables, https://github.com/ukanth/afwall/ [github.com] ), logcat, terminal which the average joe doesn't even know about them.
Until Marshmallow they didn't even protect the external sdcard/otg, just a write permission was enough to do whatever you wanted with it...
Using old and almost always unsupported kernels doesn't help it. They're full of already patched exploits. My tablet uses 3.4.2x (already on 3.4.112[1]) and my phone 3.10.49 (already on 3.10.102[1])... Just search for a while and surely you will find a way to get root.

Android is so f*cked up.

I want to develop native apps directly on my phone, but Android SDK+NDK won't even fit. Why do I need gigabytes and gigabytes of shit to build a kilobyte apk file. Fuck Google's bloated fucking bullshit developer tools.

Since adb is just 1.2mb... I installed once the developer tools, copied out adb/fastboot and removed the other stuff. They're surely bloated, they even pack emulators by default, since why not? Let's waste hard drive space.
