Intel e phatlalalitse tlhahisoleseling mabapi le sehlopha se secha sa bofokoli ho li-processor tsa eona - MDS (Microarchitectural Data Sampling). Joalo ka litlhaselo tsa nakong e fetileng tsa Specter, litaba tse ncha li ka lebisa ho lutla ha data ea beng ba sistimi e sebetsang, mechini e sebetsang, le lits'ebetso tsa kantle ho naha. Ho boleloa hore mathata a ile a tsejoa pele ke basebetsi ba Intel le balekane nakong ea tlhahlobo ea ka hare.
