Summary
In certain Arm CPUs, a CPP RCTX instruction executed on one Processing Element (PE) may inhibit TLB invalidation when a TLBI is issued to the PE, either by the same PE or another PE in the shareability domain. In this case, the PE may retain stale TLB entries which should have been invalidated by the TLBI.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
