What happened
This Microsoft Security Blog feed (May 2026) covers multiple active and strategic security topics: a newly disclosed Linux local privilege escalation dubbed “Dirty Frag” impacting kernel networking/memory-fragment handling (esp4, esp6, rxrpc) that enables reliable escalation to root and is being monitored in the wild; research showing prompt-injection can produce RCE in AI agent frameworks; large-scale credential theft/AiTM phishing campaigns using multi-stage lures and authenticated email delivery; a macOS “ClickFix” campaign using fake utility fixes and malicious Terminal commands to deliver
