Microsoft released yesterday two new Windows Update packages meant to fix the Spectre v2 vulnerability.
AMD has released CPU microcode updates for processors affected by the Spectre variant 2 (CVE-2017-5715) vulnerability. The company has forwarded these microcode updates to PC and motherboard makers to include them in BIOS updates.
Intel released an update to the Meltdown and Spectre mitigation guide, revealing that it stopped working on mitigations for some processor series.
Earlier this month, Microsoft announced it would be bundling Intel microcode (BIOS) updates meant to fix the graver version of the Spectre vulnerability as Windows Update packages made available via the Microsoft Update Catalog portal. Yesterday, Microsoft greatly expanded the number of such packages.
Intel announced yesterday that they have released updated microcodes for Skylake-based processors to OEMS and other partners that resolve the unpredictable behavior and reboots related to Spectre mitigation. On January 27th, Intel stated that they had discovered the cause of the reboots and have been able to do so in other platforms.
On January 8th Intel released new Linux Processor microcode data files that can be used to mitigate the Spectre and and Meltdown vulnerabilities in Intel CPUs. Using microcodes, an operating system can fix known bugs in Intel CPU without having to perform a BIOS update on the computer.
