Hi, My processor is part of Intel 3rd Gen Core family (3612QM | Ivy Bridge) and its affected by Spectre Side Channel attacks, see Intel Advisory article. https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00161.html Microsoft has released a powershell cmdlet to see the status of these vulnerabilties (whether hardware level mitigations are present or not). https://support.microsoft.com/en-in/help/4074629/understanding-the-output-of-get-speculationcontrolsettings-powershell I am attaching output of the relevant powershell command below, which shows that my System (DELL 14R 5420 | BIOS A19) is affected by these attacks and that Hardware level updates/mitigations/microcode updates are not present. BTIHardwarePresent and SSBDHardwarePresent flags in the output shows that Hardware level mitigations are not  present. Can you please pass on this feedback to respective team so that BIOS can be updated and released for Dell Inpiron 14R 5420.

Hello, I own Dell Inspiron 14R 5420 running Intel i7 3612QM / GT630M (Service Tag: <Service tag removed>). As I see, Del still hasn't released BIOS Update (to address INTEL-SA-00115(CVE-2018-3639&CVE-2018-3640)  ) for this model, whereas BIOS update were released for 15R 5520. 15R 5520 is just 15 inches version of 14R 5420. 15R 5520 is also running 3rd gen / Ivy Bridge processors like 14R, so I assume that 14R 5420 should get similar attention from Dell, for releasing new BIOS with updated CPU Microcode addressing sidechannel attacks. 15R received two BIOS updates in 2018 for CPU Microcode update. Prior to these two updates, 15R last released BIOS update was in 2013. 14R received last BIOS update in 2013. @ Moderators: Can you please bring this matter in attention to responsible personnel / team, so that BIOS update can be queued and prepared for Public release.   Thanks and Regards Harmandeep Saggu
