CVE-2020-35926 is a critical vulnerability affecting the nanorand crate for Rust, specifically versions prior to 0.5.1. The flaw, stemming from mishandled integer truncation, causes all random number generators within the crate to produce only zeroes, severely compromising cryptographic integrity. With a CVSS score of 9.8 (Critical), this vulnerability is easily exploitable over the network with no user interaction, leading to complete compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code, or significant community discussion has been observed, the fundamental nature of the flaw poses a significant risk to applications relying on nanorand for randomness.
