AMD won't patch all chips affected by severe data theft vulnerability — Ryzen 3000, 2000, and 1000 will not get patched for 'Sinkclose' | Tom's Hardware
AMD won't patch all chips affected by severe data theft vulnerability — Ryzen 3000, 2000, and 1000 will not get patched for 'Sinkclose' | Tom's Hardware
AMD released patches to address the Sinkclose vulnerability, but not all chips are covered. The company also said 'No performance impact expected', which means that its likely still conducting final validation and testing of the patch and how it impacts the overall performance of the system.

New AMD SinkClose flaw helps install nearly undetectable malware
New AMD SinkClose flaw helps install nearly undetectable malware
AMD is warning about a high-severity CPU vulnerability named SinkClose that impacts multiple generations of its EPYC, Ryzen, and Threadripper processors. The vulnerability allows attackers with Kernel-level (Ring 0) privileges to gain Ring -2 privileges and install malware that becomes nearly undetectable.

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…
