Not long ago news of a PS4 Root Privilege Escalation & Prison Break / Sandbox Break PoC was confirmed, and today kr105 dropped word in the Shoutbox that a usable dlclose exploit for PS4 Firmware 1.76 is now available to compile with CTurt's open-source work! :D

Download: PS4-dlclose-master.zip / PS4 Dlclose GIT / GIT / Linux Loader Patch for 1.76 / bzImage / initramfs.cpio.gz by kr105 / PS4 Playground / PS4 Playground GIT / ps4link-master.zip / PS4Link GIT
From the ReadMe Files: PS4-dlclose

PS4_Linux_Patched.jpgFully implemented dlclose exploit for PS4 fw 1.76. Compile it with CTurt's.

This is the bare working exploit, you must add your own payload code to make it do anything useful. Enjoy!

Linux loader
Code:
@@ -28,6 +28,15 @@ If you're on Linux, the easiest way is probably to use `netcat`:

After you have sent the binary, it will be executed automatically.

+### Linux loader
+You need a FAT32 formatted USB drive plugged in on any PS4's USB port with the following files on the root directory:
+
+`bzImage` : Kernel image that will be loaded. Recommended to use [this sources](https://github.com/fail0verflow/ps4-linux/tree/ps4-xhci-wip) to compile it.
+
+`initramfs.cpio.gz` : The initial file system that gets loaded into memory during the Linux startup process. [This one](https://github.com/slashbeast/better-initramfs) is recommended.
+
+The file names must match with the above and you can have more files on the same USB drive. From there you can setup the environment to run from an NFS share or from an external drive via USB (recommended) and boot a complete distro!

Well that a hard question.

First you may want to consider that there are many rumor for a new ps4k that is more powerful then the last one(also they say that it may release around late 2016-2017). That is all rumors of course.

Second the last hack is not "exactly a hack" for end users. You can not run backup games yet although you can have full access to ps4(for develop) and only for 1.76 fw. That was release a few days ago so you can not be sure what will happen in the next few days-months.

My personal opinion is to wait a few days that may something happen.The ps4 that sell at store come with 2.55 if i remember correctly so even if you buy you can't run Linux right now.That all of course my personal opinion.
