Entropy Bootstrapping for Wireless Embedded Systems

Weak randomness has broken deployed cryptography through implementation bugs, boot entropy scarcity, and backdoored generators. Inexpensive wireless sensors concentrate the risk because many boot or operate in highly deterministic conditions while relying on basic, rudimentary, or opaque RNGs. On...

CVE-2026-13199

EEPROM firmware on Raspberry Pi 5 and Compute Module 5 devices produced non-random KASLR and RNG seed values. This resulted in consistent kernel addresses across boots and devices, potentially making it easier to exploit other vulnerabilities. Additionally, the low-quality RNG seed may affect the...

kernel: x86/coco: Require seeding RNG with RDRAND on CoCo systems

CVE-2024-35875 addresses a security concern in the Linux kernel's handling of confidential computing CoCo environments. In these setups, the virtual machine VM host is untrusted and may attempt to compromise guest VMs. A critical component for maintaining security in such environments is a reliab...

UBUNTU-CVE-2024-35875

In the Linux kernel, the following vulnerability has been resolved: x86/coco: Require seeding RNG with RDRAND on CoCo systems There are few uses of CoCo that don't rely on working cryptography and hence a working RNG. Unfortunately, the CoCo threat model means that the VM host cannot be trusted a...
