Why we cannot wait for better post-quantum signature algorithms

Cloudflare security blog feed covering post-quantum cryptography migration, Linux vulnerability response, AI and frontier-model security, OAuth and non-human identity protections, MCP governance, threat-intelligence-driven WAF rules, client-side security, fraud prevention, and multi-vector attack investigation. The feed is primarily defensive and product-focused; the most security-critical item describes response to a critical Linux kernel privilege-escalation vulnerability, but no specific CVE identifier is provided.
