TRRespass: The Rowhammer Fuzzing Tool

Tracked as CVE-2020-10255, the newly reported vulnerability was discovered by researchers at VUSec Lab, who today also released 'TRRespass,' an open source black box many-sided RowHammer fuzzing tool that can identify sophisticated hammering patterns to mount real-world attacks.

According to the researchers, TRRespass fuzzer repeatedly selects different random rows at various locations in DRAM for hammering and works even when unaware of the implementation of the memory controller or the DRAM chip.

What's more? The latest flaw also affects LPDDR4 and LPDDR4X chips embedded on most of the modern smartphones, leaving millions of devices still vulnerable to the RowHammer vulnerability again.

Researchers claim they "tried TRRespass on the three major memory vendors (compromising more than 99% of the market) using 42 DIMMs," and found bit flips on 12 of them.
