The Debian Project released a new intel-microcode security update for Intel CPU microarchitectures to address a regression affecting HEDT and Xeon processors, and add mitigations for Coffe Lake CPUs. Learn more about this update:
Last month on November 13th, the Debian Project shipped updated CPU microcode for various types of Intel CPUs to mitigate the TAA (TSX Asynchronous Abort) vulnerability (CVE-2019-11135). But not all Intel CPU models were covered by the update, so they released a new intel-microcode security update that addresses this flaw for Coffe Lake processors too.
"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," reads the security advisory. "We recommend that you upgrade your intel-microcode packages."
