The microcode update for HEDT and Xeon CPUs with signature 0x50654 which was reverted in DSA 4565-2 is now included again with a fixed release.

The upstream update for Skylake-U/Y (signature 0x406e3) had to be excluded from this update due to reported hangs on boot.

For details refer to [link moved to references] [link moved to references]

For the oldstable distribution (stretch), these problems have been fixed in version 3.20200609.2~deb9u1.

For the stable distribution (buster), these problems have been fixed in version 3.20200609.2~deb10u1.

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: [link moved to references]");
