A critical flaw has been discovered in Intel’s Skylake and Kaby Lake processors, according to a warning message published by Debian.org.
The flaw is apparently present in all hyper-threaded mobile, desktop, HEDT, and embedded chips, and could result in the chips misbehaving.
The issue consists of a microcode defect which only affects the processor when hyper-threading is enabled, and the warning recommended that all affected users immediately disable hyper-threading.
Intel has fixed the issue for certain processors, but users will have to install a microcode package or BIOS update to apply the fix.
Users should reportedly disable hyper-threading in their BIOS settings and contact their system vendor to acquire an update which fixes the problem.
