Critical Update from Intel - Spectre Variant 2 - Do not patch BIOS
Intel has communicated new guidance regarding the "reboot issues" with the microcode included in the BIOS updates released to address Spectre (Variant 2), CVE-2017-5715. Dell is advising that all customers should not deploy the BIOS update for the Spectre (Variant 2) vulnerability at this time. Dell is removing the impacted BIOS updates from the web and suspending further BIOS updates for affected platforms.
If you have already applied the BIOS update, please wait for further information and an updated BIOS release, no other action is recommended at this point. Please continue to check back for updates.
As a reminder, the Operating System patches are not impacted and still provide mitigations to Spectre (Variant 1) and Meltdown (Variant 3). The microcode update is only required for Spectre (Variant 2), CVE-2017-5715.
