DirtyPipe Vulnerability
« on: March 08, 2022, 05:40:35 AM »
With TinyCore Linux extensively utilizing read-only filesystems, I wonder what impact the recently announced DirtyPipe vulnerability in the Linux kernel will have on it.

More info here: https://lwn.net/Articles/887056/

Will there by updates to TinyCore for patched versions of the kernel? Only for 13.x or will prior versions be covered too?

It's a serious bug, but it's local. Someone needs to be able to run a program on your computer. As such, there probably won't be a mid-release kernel update for 13.x.

TC is typically not used for multi-user restricted systems, where this would be a larger concern.
The only barriers that can stop you are the ones you create yourself.

I anyone is interested,

I have made a CorePure64-13.0.iso having kernel 5.15.27 and same modules as the (official) latest TinyCore release.

Build from scratch, sources from kernel.org

The DirtyPipe is fixed on this one.
