OFBD SMM Read Validation Issues

AMI APTIOV contains vulnerabilities in BIOS where
privileged users may cause the “Out-of-Bounds Read” by
local access. Successful exploitation of this vulnerability may lead to a
denial of service during firmware update processing, such as a crash or failed
update if the out-of-bounds read hits unmapped memory. It could also impact
Confidentiality, and Availability.
