Intel has addressed a vulnerability in the configuration of several CPU series that allow an attacker to alter the behavior of the chip's SPI Flash memory —a mandatory component used during the boot-up process [1, 2, 3].
HP announced today it was stopping the deployment of BIOS updates containing Meltdown and Spectre patches and reissuing older BIOS versions.
The Spectre & Meltdown mess continues with Dell now recommending their customers do not install the BIOS updates that resolve the Spectre (Variant 2) vulnerabilities. These updates have been causing numerous problems for users including performance issues, boot issues, reboot issues, and general system instability.
As Intel, AMD, and other CPU manufacturers have started releasing CPU microcode (firmware) updates for processor models affected by the Meltdown and Spectre patches, those updates are trickling down to OEMs and motherboard vendors, who are now integrating these patches into BIOS/UEFI updates for affected PCs.
