Errata patches for the kernel have been released for OpenBSD 6.3 and 6.4.

While recv(2) with the MSG_WAITALL flag was receiving control messages
from a socket, the kernel could panic.

Binary updates for the amd64, i386, and arm64 platforms are available
via the syspatch utility. Source code patches can be found on the
respective errata page:

https://www.openbsd.org/errata63.html
https://www.openbsd.org/errata64.html

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