Detail
This update ships updated CPU microcode for CFL-S (Coffe Lake Desktop) models of Intel CPUs which were not yet included in the Intel microcode update released as DSA 4565-1. For details please refer to https://www.intel.com/content/dam/www/public/us/en/security-advisory/documents/IPU-2019.2-microcode-update-guidance-v1.01.pdf Additionally this update rolls back CPU microcode for HEDT and Xeon processors with signature 0x50654 which were affected by a regression causing hangs on warm reboots (Cf. #946515). For the oldstable distribution (stretch), these problems have been fixed in version 3.20191115.2~deb9u1. For the stable distribution (buster), these problems have been fixed in version 3.20191115.2~deb10u1. We recommend that you upgrade your intel-microcode packages.
