Intel hasn’t shared many technical details around these two flaws, but they advise users to patch the vulnerabilities by applying the available BIOS updates. This is particularly problematic because motherboard vendors do not release BIOS updates often and don’t support their products with security updates for long. Considering that 7th gen Intel Core processors came out five years ago, it’s doubtful that MB vendors are still releasing security BIOS updates for them. As such, some users will be left with no practical way to fix the above flaws. In these cases, we would suggest that you set up a strong password for accessing the BIOS settings.
Intel also released a separate advisory for a high-severity elevation of privilege flaw (CVE-2021-0146) that affects several car models that use the Intel Atom E3900. “Intel has released a firmware update to mitigate this flaw, and users will get it through patches supplied by the system manufacturer,” the report says.
