Gigabyte published an advisory stating it will release the new BIOS with the latest AGESA containing the 'Sinkclose' vulnerability patch for many of its AMD motherboards in succession by the end of August. The flaw exclusively affected the entire line of AMD processors released since 2006, requiring a wide range of CPUs to be updated with a new firmware containing the required AGESA microcode.
Considering the potential of this flaw and the release of the much-needed AGESA patches, it's a norm for other motherboard makers to release the patched BIOS quickly once the AGESA patch is out. It's safe to speculate since hackers did not exploit this for 18 years, it's unlikely users would need to be concerned until they receive the BIOS for their AMD motherboards. That said, end users must update the respective motherboard BIOS once it is released. Since many motherboard makers like Gigabyte have included tools to flash BIOS quickly, it will not be difficult for most.
