Debian Security Advisory DSA-4934-1 [email protected]
https://www.debian.org/security/ Moritz Muehlenhoff
June 26, 2021 https://www.debian.org/security/faq
Package : intel-microcode
CVE ID : CVE-2020-24489 CVE-2020-24511 CVE-2020-24512 CVE-2020-24513
This update ships updated CPU microcode for some types of Intel CPUs and
provides mitigations for security vulnerabilities which could result in
privilege escalation in combination with VT-d and various side channel
attacks.
For the stable distribution (buster), these problems have been fixed in
version 3.20210608.2~deb10u1.
Note that there are two reported regressions; for some CoffeeLake CPUs
this update may break iwlwifi
(https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/issues/56)
and some for Skylake R0/D0 CPUs on systems using a very outdated firmware/BIOS,
the system may hang on boot:
(https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/issues/31)
If you are affected by those issues, you can recover by disabling microcode
loading on boot (as documented in README.Debian (also available online at
https://salsa.debian.org/hmh/intel-microcode/-/blob/master/debian/README.Debian))
We recommend that you upgrade your intel-microcode packages.
For the detailed security status of intel-microcode please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/intel-microcode

these updates to your system and frequently asked questions can be
