Debian developer Henrique de Moraes Holschuh is now warning users of a widely known GNU/Linux distribution about a new security error which is affecting Intel’s 6th and 7th generation Skylake and Kabylake processors supporting HyperThreading.
This issue has been affecting all forms of operating systems. The issue has had a huge on a huge impact on all of the Intel CPUs from the 6th and 7th generation which includes desktop, mobile. Embedded, and HEDT (High-end Desktop), as well as related server processors from the Xeon 5 and Xeon 6 series and also select Intel Pentium processor models.
The Debian Project looks to be the first to issue a warning for its users using the Debian GNU/Linux OS on their computers which has been powered by Intel’s Skylake or Kaby Lake processors with HyperThreading enabled, urging them to immediately disable the feature from the BIOS or UEFI settings or update the processor microcode.
"This defect can, when triggered, cause unpredictable system behavior: it could cause spurious errors, such as application and system misbehavior, data corruption, and data loss," reads the mailing list announcement. "Disable HyperThreading immediately in BIOS/UEFI to work around the problem."
