CVE-2025-2796

On affected platforms with hardware IPSec support running Arista EOS with IPsec enabled and anti-replay protection configured, EOS may exhibit unexpected behavior in specific cases. Received duplicate encrypted packets, which should be dropped under normal anti-replay protection, will instead be...

Versatile Quantum-Safe Hybrid Key Exchange and Its Application to MACsec

Advancements in quantum computing pose a significant threat to most of the cryptography currently deployed. Fortunately, cryptographic building blocks to mitigate the threat are already available; mostly based on post-quantum and quantum cryptography, but also on symmetric cryptography techniques...
