OpenBSD Errata: August 26th, 2017 (smap)

Errata patches for smap have been released for OpenBSD 6.1 and 6.0.

SMAP enforcement could be bypassed by userland code.

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

  https://www.openbsd.org/errata60.html
  https://www.openbsd.org/errata61.html

As this affects the kernel, a reboot will be needed after patching.
