(update 2018/05/22) New security vulnerabilities, CVE-2018-3639 and CVE-2018-3640 are derivatives of speculative execution side-channel analysis methods publicly disclosed in January 2018.(CVE-2017-5715, CVE-2017-5753 and CVE-2017-5754). As intel’s recommendation, mitigation of these 2 new variants require both BIOS and OS/VMM update. Please refer to the link for new BIOS release version and schedule - http://www.qct.io/Press-Releases/index/PR/Server/Intel-SA-00115.
(update 2018/03/09) QCT has received new microcode for Skylake/Broadwell/Haswell/IvyBridge/SandyBridge CPU from Intel.Please refer to ‘’Table 1 - BIOS updates for QCT products’’ for BIOS fixed version and available week.
(update 2018/02/27) QCT has received new microcode for Broadwell/Haswell servers from Intel. We will release BIOS for D51B-1U/2U, D51BP-1U/2U, T41S-2U and T41SP-2U in WK09 and will keep you posted when other projects are available. Please refer to BIOS fixed version and release week in table 1.

Regarding Customized BIOS, please contact your account sales for release schedule and BIOS with microcode.
As intel’s recommendation, mitigation of these 3 variants require both OS and BIOS update. (Table 2 - Security issue variants)
Please check with OS or VM vendors for related information.

(Rough data Load)
===== Updated 2018/1/4 =====
An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions
The security vulnerability affected QCT’s server and storage product lines. QCT had made update microcode available for most of our recent release products on the product download page. We highly recommend our customer allocate validation resource to implement new BIOS with update microcode. These vulnerabilities are not unique to QCT servers and will affect any systems using modern microprocessor architectures with impacted firmware revisions.
