Critical BIOS Update Needed for Older Intel CPUs with Gigabyte Motherboards

Update your BIOS if using Intel's 8–11th Gen CPUs with Gigabyte motherboards to address serious vulnerabilities.

If you’re using an older Gigabyte motherboard with an Intel CPU—up to and including a Z590/B560 chipset—you should probably update your BIOS. Some vulnerabilities have been found that could allow serious memory corruption.

In an official security update, Gigabyte explained they have identified multiple memory corruption vulnerabilities in the System Management Mode (SMM) modules of several older consumer motherboards.

While the newer hardware is reportedly unaffected, it’s important for users of Z590 and B560 boards, which are compatible with Intel 10th and 11th Gen CPUs, to apply these updates.

The following summarizes the affected chipsets along with their BIOS release timelines:

Chipset BIOS Release Schedule

Intel Z170, H170, B150, Q170 EOL, Contact for support
Intel Z270, H270, B250, Q270 EOL, Contact for support
