GPUThor: Amplifying Rowhammer Attacks Via Non-Uniform Patterns to Exploit ECC-Protected GPUs

GDDR memory in GPUs is vulnerable to Rowhammer attacks, where rapid memory accesses induce bit flips in adjacent cells, enabling data tampering and privilege escalation. However, prior GPU Rowhammer attacks trigger only tens to hundreds of bit flips, orders of magnitude fewer than CPU attacks,...

JENGA: Exploiting Counter-Based RowHammer Countermeasures to Break Real-Time Predictability

Safety-critical real-time systems must satisfy multiple dependability requirements, notably time predictability and security. In such systems, tasks must complete within bounded and known execution times, typically characterised through Worst-Case Execution Time WCET analysis. At the same time,...

New GPUThor Rowhammer Defeats ECC on NVIDIA RTX A6000 to Gain Host Root Access

Academic researchers have disclosed a Rowhammer attack impacting NVIDIA workstation GPUs with GDDR6 memory that defeats error correction codes ECC, the mitigation NVIDIA recommends against GPU Rowhammer, and enables denial-of-service DoS and privilege escalation to a root shell. Dubbed GPUThor ,...

From Fleet to Lab: Revisiting the Security and Complexity of Industrial Rowhammer Mitigation

This paper studies efficient and secure Rowhammer mitigation at the Memory-Controller MC. Rowhammer mitigation faces a fundamental tradeoff between tracking storage and mitigation rate: precise trackers such as Misra-Gries avoid unnecessary mitigations but require large CAM structures, whereas...

Security Notice: NVIDIA Rowhammer - August 2026

NVIDIA has released updated guidance regarding Rowhammer mitigations for NVIDIA GPU and SoC products. NVIDIA recommends a defense-in-depth posture, including enabling SYS-ECC and host IOMMU / DMA isolation. See details below. Go to NVIDIA Product Security. Details NVIDIA received follow-on resear...

Bit-Flip Attacks on Vision-Language-Action Models: Action-Decoding Architecture Shapes the Vulnerability

Quantized Vision-Language-Action VLA models expose a weight-fault surface: Rowhammer-style faults can corrupt deployed INT8 bits. We present the first bit-flip attack on a VLA: a few gradient-selected flips reduce closed-loop success to $0%$, while hundreds of random flips are harmless. Across...

Demystifying DRAM Read Disturbance: Bridging the Gap between Experimental Characterization and Device-Level Modeling of RowHammer and RowPress Phenomena

DRAM read disturbance, like RowHammer and RowPress, is a critical robustness issue where accessing DRAM can cause unintended bitflips in other unaccessed DRAM locations. DRAM read disturbance bitflips significantly impact the safe, secure, and reliable operation of DRAM-based computing systems...

JLSEC-2026-675

An issue was discovered in wolfSSL before 5.5.0. A fault injection attack on RAM via Rowhammer leads to ECDSA key disclosure. Users performing signing operations with private ECC keys, such as in server-side TLS connections, might leak faulty ECC signatures. These signatures can be processed via ...

JLSEC-2026-683 An issue was discovered in wolfSSL before 5.7.0

An issue was discovered in wolfSSL before 5.7.0. A safe-error attack via Rowhammer, namely FAULT+PROBE, leads to ECDSA key disclosure. When WOLFSSLCHECKSIGFAULTS is used in signing operations with private ECC keys, such as in server-side TLS connections, the connection is halted if any fault...

Mechanised Operational Semantics of Rowhammer

Rowhammer is a hardware vulnerability in dynamic random-access memory DRAM in which repeated accesses to aggressor rows can induce bit-flips in victim rows. This phenomenon violates a core assumption of conventional programming language semantics: reading or writing one memory location does not...

AutoPRAC: Automating Attack Discovery for PRAC-Based Rowhammer Defenses Using Model Checkers

Per-Row Activation Counting PRAC in DDR5 is a specification to mitigate Rowhammer attacks by tracking activations per row and triggering mitigative refreshes when needed. However, the security of PRAC designs is currently evaluated using human-crafted attack patterns and we lack formal verificati...

Model Poisoning against Federated Model Adaptation with Chain of Bit-Flips

Federated Learning FL allows a set of clients to collectively train a global model without sharing local training data. Giving the responsibility of the training to decentralized actors may lead to poisoning attacks: clients controlled by malicious third party potentially poison the training...

ARTA: Adaptive Reinforcement-Learning-Based Throttling Agent for RowHammer Vulnerabilities

RowHammer vulnerability continues to intensify with DRAM scaling, reducing the activation threshold needed to induce bitflips and rendering existing defenses such as TRR, ECC, and refresh-based mechanisms vulnerable to sophisticated multi-bank hammering patterns. This work presents ARTA, a...

ScaleDisturb: Exploiting Temporal Asymmetry to Amplify Read Disturbance in Modern DRAM Chips

DRAM suffers from read disturbance phenomena e.g., RowHammer and RowPress, where repeatedly accessing or continuously keeping open a DRAM row aggressor row induces bitflips in other physically nearby unaccessed rows victim rows. The disturbance mechanism is practically exploitable from the softwa...
