For affected CPUs, to fully mitigate the vulnerability it is also necessary to update the Linux kernel packages as released in DSA 4564-1.

For the oldstable distribution (stretch), these problems have been fixed in version 3.20191112.1~deb9u1.

For the stable distribution (buster), these problems have been fixed in version 3.20191112.1~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]");
