CVE-2026-47289 Jun 09, 17:17 HIGH PATCH NEWS Exploit Unlikely This Week

Heap-based buffer overflow in Microsoft Remote Desktop Client enables remote code execution when a user connects to a malicious RDP server, with the attacker gaining the same privileges as the connecting user. The CVSS 8.8 score reflects network-reachable exploitation requiring only minimal user interaction (initiating an RDP session), and no public exploit has been identified at time of analysis. The flaw is reported by Microsoft Security Response Center (secure@microsoft.com) and is categorized as CWE-122 heap-based buffer overflow.

CVE-2026-47288 Jun 09, 17:17 HIGH PATCH NEWS This Week

Remote code execution in Microsoft Windows Kerberos implementation allows an authenticated attacker on an adjacent network segment to trigger an integer overflow and execute arbitrary code. The flaw is rated CVSS 7.1 (High) with high attack complexity and requires low-level privileges, and at the time of analysis there is no public exploit identified. Because Kerberos is a core authentication service in Windows domain environments, successful exploitation has direct implications for domain trust and identity security.

CVE-2026-34334 May 12, 16:59 HIGH PATCH This Week

Local privilege escalation in the Microsoft Windows TCP/IP networking stack allows an already-authenticated attacker to win a race condition and elevate to SYSTEM-level privileges across a broad range of Windows client and server releases (Windows 10 1607 through Windows 11 26H1, and Windows Server 2012 through 2025). Exploitation requires local, low-privileged access rather than remote reach, and Microsoft rates the technical impact as total (full confidentiality, integrity, and availability loss). There is no public exploit identified at time of analysis and EPSS probability is very low (0.04%), consistent with CISA SSVC marking exploitation as none and not automatable.
