  2. eMudhra CA private keys trivially broken

    Eight eMudhra intermediate CA private keys were found to have near-zero entropy (values like 4, 56, and 115 instead of 384-bit keys), enabling trivial certificate forgery for any domain; Chrome, Mozilla, Apple, and Microsoft revoked trust and deployed blocks, while Python, Node.js, and Linux certificate bundles shipped emergency updates.
