Bug 30037

Intel model: NUC10i7FNB
6-Core Intel Core i7-10710U, x86_64.
Updated latest microcode and rebooted to latest desktop kernel.
$ dmesg | grep microcode
[    0.000000] microcode: microcode updated early to revision 0xea, date = 2021-04-28
[    0.863197] microcode: sig=0xa0660, pf=0x80, revision=0xea
[    0.863450] microcode: Microcode Update Driver: v2.2.

Looks like this machine is not affected.

CC: (none) => tarazed25

 it should be as its a gen 10 and the updates started from ~gen6

dont mind the date... some of the microcode updates Intel sit on foe a _long_ time or only release as part of vendor bios updates...

Here is What happend on my i3-6xxx storage server:

dmesg.old:[    0.000000] microcode: microcode updated early to revision 0xea, date = 2021-01-05
dmesg.old:[    2.424498] microcode: sig=0x906eb, pf=0x2, revision=0xea

dmesg.new:[    0.000000] microcode: microcode updated early to revision 0xec, date = 2021-04-28
dmesg.new:[    2.414868] microcode: sig=0x906eb, pf=0x2, revision=0xec

  Updated microcodes for Intel processors, fixing various functional

  Insufficient control flow management in some Intel(R) Processors may allow
  an authenticated user to potentially enable a denial of service via local
  access (CVE-2021-0127 / SA-00532).

  Hardware allows activation of test or debug logic at runtime for some
  Intel(R) processors which may allow an unauthenticated user to potentially
  enable escalation of privilege via physical access
  (CVE-2021-0146 / SA-00528).

My newest Intel processor is an i5-2500, second generation, and thus should not be affected. And,

$ dmesg | grep microcode
[    0.000000] microcode: microcode updated early to revision 0x2f, date = 2019-02-17
[    0.580381] microcode: sig=0x206a7, pf=0x2, revision=0x2f
[    0.580477] microcode: Microcode Update Driver: v2.2.

would seem to confirm that. No issues noted, anyway.

Also updated a Core2Quad, also with no issues.
