OpenBSD Errata: March 13th, 2020 (sosplice)
12 March, 2020 by firstname.lastname@example.org | openbsd
Errata patches for the kernel have been released for OpenBSD 6.5 and 6.6. Local outbound UDP broadcast or multicast packets sent by a spliced socket can crash the kernel. 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/errata65.html https://www.openbsd.org/errata66.html As these affect the kernel, a reboot will be needed after patching.
