Phoronix: Intel Releases Updated CPU Microcode For Fixing Three New Security Issues

Intel just published a new set of CPU microcode files for updating Alder lake and newer as well as Xeon Scalable 4th Gen and 5th Gen in order to address three security issues plus take care of various functional issues...

Intel hardware seems very more prone to security issues than the rest...

authenticated users with local access could obtain information disclosure from the system.

Sounds a bit awkward. Maybe "could obtain information from the system"?

Does AMD hardware have as many securities issues as Intel?
Does Apple hardware and Qualcomm ARM-based hardware have as many issues as Intel and AMD x86-based hardware?

Did older CPU generations like the 386 and 486 and Pentium 1 and II have issues like this or is it only Core generation and newer having this?

Maybe not as many, but enough.

To start with security at time was completed diffent think.
1. Most computer was not connected to bbs or internet so attact vector from internet did not exists.
2. Often you did only run one program at time ( expect for virus)
3. The cpu design was more simple what it is now

But bug in the opcode did exists plenty of it.
if you did use some asm code doing div correct but next time you run it it gave diffent answers in special case (op did wrong think did not clean the state something, do not rember exacly you where force rest the state manual. ).
when mmx come it was some issue betwin fpu and mmx part some bugs their.
so on.

But intel did not have a way patch the cpu in that area.
the provide a guide for devloper which op code and asm instructions you should avoid instead.

I do not rember which cpu did have what bug in my head.
I write done what i rember from thuse cpu

Most of those vulnerabilities come from multi core or hyper threading getting access to other threads memory, that's why those old CPUs didn't have similar problems. But as was mentioned above, hardware bugs in general are not new, most famous Intels Pentium-FDIV-Bug.
