Errata patches for the kernel have been released for OpenBSD 6.3 and 6.2. IO port permissions were incorrectly restricted.
Binary updates for the i386 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 As these affect the kernel, a reboot will be needed after patching.
