0Intel recommended to stop deploying the current versions of Spectre/Meltdown patches
Intel recommended OEMs, cloud service providers, system manufacturers, software vendors as well as end users to stop deploying the current versions of Spectre/Meltdown patches.
While the Linux father Linus Torvalds defines the Spectre updates âutter garbageâ, Intel warns to stop installing current versions of Spectre/Meltdown patches.
Intel explained its approach in its technical note about Spectre mitigation (âSpeculative Execution Side Channel Mitigationsâ), the tech giant addressed the issue with an opt-in flag dubbed IBRS_ALL bit (IBRS states for Indirect Branch Restricted Speculation).
The Indirect Branch Restricted Speculation, along with Single Thread Indirect Branch Predictors (STIBP) and Indirect Branch Predictor Barrier (IBPB), prevent the abuse of the prediction feature and the exploitation of the flaw.
Torvalds speculate the Intelâs decision to address the issues in this way is mainly motivated by the intention to avoid legal liability. Recalling two decades of flawed chips would have a catastrophic impact on the tech giant.
Torvalds explained that the impact of using IBRS on existing hardware is so severe that no one will set the hardware capability bits.
Users and IT companies are reporting severe problems after installing the patches, such as a significant degradation of performance and unwanted reboots.
Intel recommended OEMs, cloud service providers, system manufacturers, software vendors as well as end users to stop deploying the current versions of Spectre/Meltdown patches. The company announced to have found the root cause of reboot issued for Broadwell and Haswell platforms and is asking to wait for a fix.

The tech giant began rolling out to industry partners a beta update to address the issue.
âAs we start the week, I want to provide an update on the reboot issues we reported Jan. 11. We have now identified the root cause for Broadwell and Haswell platforms, and made good progress in developing a solution to address it.âIntel said in a press release published on Monday. âOver the weekend, we began rolling out an early version of the updated solution to industry partners for testing, and we will make a final release available once that testing has been completed.âÂ
Letâs hope Intel will release new Spectre/Meltdown patches soon
