Remote code execution in Microsoft Windows DNS lets an unauthenticated attacker corrupt heap memory over the network and run arbitrary code on affected Windows 11 (22H3 through 26H1) and Windows Server 2022/2025 systems. The flaw is a CWE-122 heap-based buffer overflow rated CVSS 9.8, reported by Microsoft with a patch available; there is no public exploit identified at time of analysis, and the EPSS score is very low (0.07%), so this is a high-severity but not-yet-exploited issue. CISA SSVC flags it as automatable with total technical impact, meaning successful exploitation fully compromises the host.
Local privilege escalation in the Windows Server Data Deduplication feature (dedup.sys / associated services) lets an authenticated low-privileged user corrupt kernel memory to gain SYSTEM-level rights. Reported by Microsoft across Windows Server 2012 R2 through 2025, it carries a CVSS 7.8 and total technical impact per CISA SSVC, but has no public exploit identified at time of analysis and a very low EPSS of 0.04% (13th percentile). It is not listed in CISA KEV and shows no evidence of active exploitation.
Remote code execution in the Windows Netlogon service (across Windows Server 2012 through 2025) allows an unauthenticated attacker to run arbitrary code over the network by triggering a stack-based buffer overflow (CWE-121). With a CVSS 3.1 vector of AV:N/AC:L/PR:N/UI:N and total technical impact, this is a critical, pre-authentication server-side flaw. Microsoft has released patches; publicly available exploit code exists, though EPSS remains low (0.09%) and there is no confirmed active exploitation at time of analysis.

The flaw stems from external control of a file name or path (CWE-73) inside the kernel-mode WinSock support driver, yielding total confidentiality, integrity, and availability impact per CVSS 7.8. There is no public exploit identified at time of analysis, EPSS is very low (0.07%), and CISA SSVC records exploitation as none, but the total technical impact and near-universal Windows footprint make it a standard Patch Tuesday priority.

The flaw affects essentially the entire supported Windows client and server lineup, from Windows 10 1607 and Server 2012 through Windows 11 26H1 and Server 2025. There is no public exploit identified at time of analysis, and the low EPSS score (0.14%) plus CISA SSVC 'Exploitation: none' indicate no observed exploitation despite the broad footprint.
Local privilege escalation in the Microsoft Windows SMB Client (mrxsmb/rdbss) driver lets a low-privileged, authenticated user corrupt kernel memory through a use-after-free (CWE-416) and elevate to SYSTEM. The flaw affects a broad range of Windows client and server builds from Windows Server 2012 R2 through Windows 11 25H2/26H1 and Server 2025. There is no public exploit identified at time of analysis, EPSS is very low (0.04%), and CISA SSVC rates exploitation as 'none' - but technical impact is 'total', so it remains a meaningful patch-Tuesday-class local EoP.
Local privilege escalation in Microsoft Windows Kernel-Mode Drivers allows an already-authenticated attacker to elevate to SYSTEM by triggering a use-after-free (CWE-416) memory-corruption condition. All supported Windows client and server releases from Windows Server 2012 through Windows 11 25H2/26H1 and Windows Server 2025 are affected, but there is no public exploit identified at time of analysis and EPSS probability is very low (0.04%).
