Cybersecurity researcher 'Chaotic Eclipse' has released two new zero-day exploits, YellowKey and GreenPlasma, targeting Windows systems. YellowKey represents a critical BitLocker bypass that utilizes the Windows Recovery Environment to provide unrestricted access to protected volumes, reportedly even in some TPM-protected environments. Meanwhile, the Linux community is tracking CVE-2026-46300, known as Fragnesia, which joins the 'Dirty Frag' class of vulnerabilities enabling local privilege escalation to root. This episode explores these unpatched threats and coordinated vulnerability disclosure tensions between researchers and major vendors like Microsoft.
