CVE-2021-29937 is a critical memory safety vulnerability in the Rust `telemetry` crate (versions prior to 0.1.3) that allows freeing uninitialized memory, leading to undefined behavior, potential crashes, and possible code execution. The fix involves upgrading the crate from version 0.1.0 to 0.1.3, which patches the unsafe memory handling at the root cause. Despite Rust's reputation for memory safety, this vulnerability demonstrates that `unsafe` code blocks can still introduce serious bugs that
CVE-2026-41676 is a high-severity vulnerability in the rust-openssl crate, which provides OpenSSL bindings for Rust applications. The fix involves upgrading the dependency from version 0.10.75 to 0.10.78 in the project's Cargo.lock file, closing a security gap that could expose applications to adversarial exploitation. Keeping cryptographic dependencies current is one of the most impactful and straightforward security practices any Rust team can adopt.
CVE-2026-41676 is a high-severity vulnerability discovered in the rust-openssl crate, which provides OpenSSL bindings for Rust applications. Left unpatched, this flaw could expose backend services to cryptographic or memory-safety attacks through the underlying OpenSSL layer. The fix involved upgrading the rust-openssl dependency from version 0.10.75 to 0.10.78 in the project's Cargo.toml and Cargo.lock files.
