#oneflip : one flip to rule them all.
The linked paper by students of George Mason University (Xiang Li et al (2025): "Rowhammer-Based Trojan Injection:
One Bit Flip Is Sufficient for Backdooring DNNs") descibes how flipping a single bit suffices to corrupt the output of high-precision a.i.-s based on deep neural networks.
Of course there are no mitigations: none of the creators imagined malice.
