Subject: hw/smbios: Fix OEM strings table option validation
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e8ddec58053e9361b2cc18ec6d17b6c95590bf3c;p=qemu.git

hw/smbios: Fix OEM strings table option validation

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.

Fixes: 2d6dcbf93fb0 ("smbios: support setting OEM strings table")
