OpenBSD 7.5 errata 005, August 2, 2024:

sndiod(8) main process could crash due to buffer overread.

Apply by doing:
   signify -Vep /etc/signify/openbsd-75-base.pub -x 005_sndiod.patch.sig \
       -m - | (cd /usr/src && patch -p0)

And then rebuild and install sndiod:
   cd /usr/src/usr.bin/sndiod
   make obj
   make
   make install
