as informed in Like all of the Rowhammer attacks which have preceded it, the GLitch proof-of-concept exploit is not mature sufficient to pose an immediate menace to generality finish users. What's more, the GLitch investigators found, mobile GPU caches have deterministic behaviors which contrast sharply with the random policies implemented in mobile CPUs. Rowhammer attacks rely on side channels to chart out big chunks of memory stored inside vulnerable chips. To surgically hammer the rows storing targeted bits, Rowhammer attacks cautiously measure when certain DRAM accesses take. Frigo told his teammates have not yet studied the mitigations, however he expects they would make Rowhammer attacks much harder.

The attack reduces the bar to pulling off so-called rowhammer attacks which flip bits in physical memory to ram out of in-built security protections. Meanwhile, the GPU allows for "fast double-sided DRAM access, enabling the rowhammer attack".
