[info/news] ... the intel Bug ! (Kernel Memory Leak)

[info/news] ... the intel Bug ! (Kernel Memory Leak)
I was reading a few Articles on how Intel messed up big time with their CPU Design,
and how all OS's have to rearrange how the Kernel is accessed etc etc

One of these Articles: http://www.theregister.co.uk/2018/01/02/...sign_flaw/

And I was thinking " Damn ! What a headache for the Dev's... ",

and then I realised it's a 64-bit problem !! Oh, well ... lol

RE: [info/news] ... the intel Bug ! (Kernel Memory Leak)
Thanks !

I read maybe more now ...
They checked on 64bit, but this does not exclude 32bit.
The problem is one of the oldest errors, memory_leak.
https://en.wikipedia.org/wiki/Memory_leak

Only in this case the error occurs in ASLR
https://en.wikipedia.org/wiki/Address_sp...domization

However,
Repairing the equipment will not repair the mindlessness of people.
Because similar memory leak can be created inside source code.

The first corrections in kernel was in December. ( KAISER / KPTI)

However, it was not only one problem last time. ( were also others )
- Ubuntu had problem with new kernel and Bios.
- Probably Debian had problem with leak ( "anyone can get root privileges" )

Edited 24.05.2018
Suse guide applies to the newer kernels (fo now), which have already received updates.
And this is added to the kernel documentation, for example:
https://git.kernel.org/pub/scm/linux/ker...2=v4.14.42
( path inside source code /Documentation/admin-guide/kernel-parameters.txt )
