ZenHammer: Rowhammer Attacks on AMD Zen-based Platforms
ZenHammer: Rowhammer Attacks on AMD Zen-based Platforms
Our work shows that it is possible to trigger Rowhammer bit flips on DDR4 devices on AMD Zen 2 and Zen 3 systems despite deployed TRR mitigations. This result proves that AMD systems are equally vulnerable to Rowhammer as Intel systems, which greatly increases the attack surface, considering today’s AMD market share of around 36%… Read

China blocks use of Intel and AMD chips in government computers, FT reports
China has introduced guidelines to phase out U.S. microprocessors from Intel (INTC.O), opens new tab and AMD (AMD.O), opens new tab from government personal computers and servers, the Financial Times reported on Sunday. The procurement guidance also seeks to sideline Microsoft's (MSFT.O), opens new tab Windows operating system and foreign-made database software in favour of domestic options, the report said.

LeftoverLocals: Listening to LLM responses through leaked GPU local memory
LeftoverLocals: Listening to LLM responses through leaked GPU local memory
By Tyler Sorensen and Heidy Khlaaf We are disclosing LeftoverLocals: a vulnerability that allows recovery of data from GPU local memory created by another process on Apple, Qualcomm, AMD, and Imagination GPUs. LeftoverLocals impacts the security posture of GPU applications as a whole, with particular significance to LLMs and ML models run on impacted GPU…
