• OpenBSD Errata: November 22nd, 2019 (inteldrm)

    From T.J. Townsend@21:1/5 to All on Fri Nov 22 06:55:02 2019
    Errata patches for the kernel have been released for OpenBSD 6.5 and 6.6.

    A local user could cause the system to hang by reading specific registers
    when Intel Gen8/Gen9 graphics hardware is in a low power state.

    A local user could perform writes to memory that should be blocked with
    Intel Gen9 graphics hardware.

    Binary updates for the amd64 and i386 platforms are available via the
    syspatch utility. Source code patches can be found on the respective
    errata page:

    https://www.openbsd.org/errata65.html
    https://www.openbsd.org/errata66.html

    As these affect the kernel, a reboot will be needed after patching.
