[PULL 05/15] hw/smbios: Fix OEM strings table option validation
Posted by Michael Tokarev 9 months, 2 weeks ago
From: Akihiko Odaki <akihiko.odaki@daynix.com>

qemu_smbios_type11_opts did not have the list terminator and that
resulted in out-of-bound memory access. It also needs to have an element
for the type option.
