• OpenBSD Errata: August 24th, 2018 (vmml1tf)

    From T.J. Townsend@21:1/5 to All on Fri Aug 24 13:20:02 2018
    Errata patches for the kernel have been released for OpenBSD 6.3 and 6.2.

    The Intel L1TF bug allows a vmm guest to read host memory.

    Binary updates for the amd64 platform are available via the syspatch utility. Source code patches can be found on the respective errata pages:

    https://www.openbsd.org/errata62.html
    https://www.openbsd.org/errata63.html

    Run the fw_update command to get updated CPU microcode before rebooting.
    If your machine has SMT ("hyper-threading") capability, it must be disabled
    in the BIOS.

    The CPU microcode update is not available for OpenBSD 6.2, so a BIOS update
    is required to receive the accelerated L1 cache solution there.
