scallion

2020 Project Update Scallion was a hobby project to learn OpenCL and RSA. We are not currently maintaining scallion. It has bitrotted in two important ways: 1. Tor has moved on to v3 Onion addresses, which scallion does not support. Old v2 addresses will stop working in October of 2021. The new...

Astra Linux – Vulnerability in Chromium

The use of “after free” in GPUs in Google Chrome before version 151.0.7922.109 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape through a crafted HTML page. Chromium security severity: High...

Towards TEE-Certified DP: Verifiable Differentially Private Training on Legacy GPUs

Wide adoption of machine learning has created growing policy and regulatory demand for protecting sensitive training data, with differential privacy DP emerging as a key mechanism. Yet a less-studied problem is how to certify the faithful execution of DP during training: an external verifier shou...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the drm/amdgpu/mes component where a loop limit for hung queue db array was incorrectly set to only AMDGPU MAX MES PIPES iterations. On multi-XCC X-Complexity Cluster...

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,...

CVE-2026-49269: Exposure of Sensitive Information to an Unauthorized Actor

Apple M1 GPUs retain register file data between compute shader dispatches from different processes. A sandboxed Metal attacker app can run a GPU reader shader that reads stale register values left by a separate sandboxed victim app. In the proof of concept, GPUVictim.app generates a fresh random...

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix sync handling in amdgpudmabufmovenotify Invalidating a dmabuf will impact other users of the shared BO. In the scenario where process A moves the BO, it needs to inform process B about the move and process B will...

Rowhammer Attack Against NVIDIA Chips

A new rowhammer attack gives complete control of NVIDIA CPUs. On Thursday, two research teams, working independently of each other, demonstrated attacks against two cards from Nvidia’s Ampere generation that take GPU rowhammering into new--­and potentially much more consequential--­territory: GDD...
