Summary

Hide ▲

A January 2026 coordinated security update fixed 12 previously unknown vulnerabilities in OpenSSL, a widely used cryptographic library. The release matters because OpenSSL underpins a large share of secure communications, so defects in it can affect many downstream systems. The update covered flaws across more than eight subsystems, including message parsing, QUIC, and post-quantum signature handling. One addressed issue was a high-severity stack buffer overflow that could enable remote code execution under specific conditions.
