Errata patches for IPsec have been released for OpenBSD 6.3 and 6.2.
A malicious packet can cause a kernel crash when using IPsec over IPv6.
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 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.
