OpenBSD Errata: October 6th, 2020 (mmap)

Errata patches for the kernel have been released for OpenBSD 6.7.

mmap can exhaust kernel memory for PROT_NONE MAP_SHARED mappings.

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

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