ASRock was just informed by Intel that they disclosed the reboot issue on the former microcode released earlier. To fix the security vulnerability (SA-00088), ASRock is still waiting for Intel's further support and we're committed to work closely with them to develop and update new BIOS for our 8/9/100/200/Z370/X99/X299 motherboard series. To mitigate this issue promptly and constructively, we will keep our customers posted on our official website, please refer to this page. For Intel's official announcement, please refer to this page.

ASRock is aware that the current Intel microcode version might be defected by security vulnerabilities. We recommend users update their systems by flashing the latest BIOS once the revision microcode is released from Intel. To mitigate this issue promptly and constructively, please refer to below links for more info and stayed tuned.DOWNLOAD: Latest ASRock BIOS Updates
