I should also mention that we will be following Debian's lead and not updating this for Trusty. Lack of early upload being one of the big reasons for this.
** Description changed: [Impact] * A security fix has been made available as part of intel-microcode * It is advisable to apply it * Thus an SRU of the latest intel-microcode is desirable for all stable releases [Test Case] * Upgrade intel-microcode package, if it is already installed / one is running on Intel CPUs * Reboot and verify no averse results, and/or that microcode for your - cpu was loaded by expecting + cpu was loaded as expected. [Test case reporting] * Please paste the output of: dpkg-query -W intel-microcode grep -E 'model|stepping' /proc/cpuinfo | sort -u journalctl -k | grep microcode [Regression Potential] Microcode are proprietary blobs, and can cause any number of new errors and regressions. Microcode bugs have been reported before, therefore longer than usual phasing and monitoring of intel-microcode bugs should be done with extra care. + + [Other] + caml discussion describing test case to reproduce the crash. + https://caml.inria.fr/mantis/view.php?id=7452 + + ========================================================================= [Original bug report] NB: I am *not* directly affected by this bug. Henrique emailed a warning to Debian devel today [1] on a potentially serious issue with (sky|kaby)lake processors. Excerpt: "This warning advisory is relevant for users of systems with the Intel processors code-named "Skylake" and "Kaby Lake". These are: the 6th and 7th generation Intel Core processors (desktop, embedded, mobile and HEDT), their related server processors (such as Xeon v5 and Xeon v6), as well as select Intel Pentium processor models. TL;DR: unfixed Skylake and Kaby Lake processors could, in some situations, dangerously misbehave when hyper-threading is enabled. Disable hyper-threading immediately in BIOS/UEFI to work around the problem. Read this advisory for instructions about an Intel-provided fix." It is probably a good idea to: (1) issue a warning to our users about this; (2) update intel-microcode on all our supported releases I leave the discussion on whether this can have security implications to others.
