Microsoft has patched multiple zero-day vulnerabilities in Windows, including two critical security flaws that allow attackers to bypass BitLocker encryption and another that enables privilege escalation through the CTFMON system component. The BitLocker bypasses are particularly concerning as they could allow attackers to access encrypted data on compromised systems, while the CTFMON vulnerability lets malicious actors gain elevated system privileges. These patches are part of Microsoft's regular security update cycle and users are urged to apply them immediately to protect against potential exploitation.
