OpenBSD Errata: November 29th, 2018 (uipc)
29 November, 2018 by firstname.lastname@example.org | openbsd
Errata patches for the kernel have been released for OpenBSD 6.3 and 6.4. UNIX domain sockets leak kernel memory with MSG_PEEK on SCM_RIGHTS, or can attempt excessive memory allocations leading to a crash. 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.
