Windows DNS Server on a broad range of Windows and Windows Server editions contains a heap-based buffer overflow rooted in a numeric truncation error, enabling an authorized local attacker with high-privilege access to escalate privileges on the affected system. Affected platforms span Windows Server 2012 through Server 2025 and Windows 10/11 across multiple feature versions, with Microsoft confirming full confidentiality, integrity, and availability impact upon successful exploitation. No public exploit code or active exploitation has been identified at time of analysis; SSVC classifies exploitation status as none and automatable as no, and Microsoft has released patches addressed in the MSRC advisory.
Authentication bypass in Windows Schannel allows a network-based attacker to circumvent cryptographic signature validation, achieving high-integrity impact without requiring prior privileges. Schannel, Microsoft's TLS/SSL security provider, fails to properly verify cryptographic signatures - tagged as a JWT attack vector - enabling forged or malformed tokens to pass validation and bypass security feature enforcement. No active exploitation is confirmed (SSVC: exploitation=none; not listed in CISA KEV), and the high attack complexity and required user interaction constrain opportunistic mass exploitation despite the broad Windows version footprint.
Tampering via partial string comparison in the Windows HTTP Protocol Stack (http.sys) exposes a broad range of Windows client and server editions to integrity compromise by unauthenticated adjacent-network attackers. Affected platforms span Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 through Server 2025, with Microsoft tagging the issue as an authentication bypass rooted in CWE-187. No public exploit has been identified at time of analysis, and Microsoft has released patched builds across all affected product lines.
Information disclosure in Windows Win32K affects a broad range of Microsoft Windows client and server operating systems, from Windows Server 2012 through Windows 11 26H1 and Server 2025. A locally authenticated low-privilege user can trigger a buffer over-read (CWE-126) in the Win32K kernel-mode subsystem, causing the kernel to return out-of-bounds memory contents to user space. No public exploit code has been identified at time of analysis, and CISA SSVC rates exploitation status as none with partial technical impact, though the kernel information disclosure primitive carries chaining risk for privilege escalation.
Integer underflow (CWE-125) in the Windows DHCP Server service exposes server memory contents to unauthenticated attackers positioned on the same adjacent network segment. Affecting Windows Server versions from 2012 through 2025 (confirmed by ENISA EUVD-2026-56370), the flaw allows crafted DHCP packets to trigger an out-of-bounds read, resulting in high-confidence confidentiality impact with no integrity or availability consequences. No public exploit code has been identified at time of analysis, and CISA SSVC rates exploitation status as none with partial technical impact - a vendor patch is available via Microsoft MSRC.
Out-of-bounds read in the Windows Win32K kernel graphics subsystem exposes kernel memory contents to a locally authenticated low-privilege attacker across a wide swath of Windows desktop and server releases, from Windows 10 1607 and Server 2012 through Windows 11 26H1 and Server 2025. The impact is strictly information disclosure - high confidentiality loss with no integrity or availability effect - making this most practically useful as a KASLR-bypass building block in a multi-stage local privilege escalation chain. No public exploit or active exploitation has been identified; SSVC classifies exploitation status as none and technical impact as partial.
Integer underflow in the Windows DHCP Server service exposes out-of-bounds memory to unauthenticated attackers on the adjacent network, enabling high-impact information disclosure across multiple Windows Server generations from 2012 through 2025. The CVSS vector (AV:A/AC:L/PR:N/UI:N) confirms exploitation requires no credentials and no user interaction, only Layer 2 or broadcast-domain adjacency to a host running the DHCP Server role. Microsoft has released patches for all affected builds; no public exploit code has been identified and the vulnerability does not appear in CISA KEV at time of analysis.
Windows Imaging Component (WIC) across a broad span of Windows 10, Windows 11, and Windows Server releases contains an uninitialized memory read flaw (CWE-908) that an authorized local user with low privileges can exploit to disclose sensitive information from process memory. The CVSS vector (AV:L/PR:L/C:H/I:N/A:N) confirms this is strictly a local, low-privilege information disclosure with no network attack surface and no integrity or availability impact. No public exploit code has been identified and this CVE is not listed in the CISA Known Exploited Vulnerabilities catalog; a vendor-released patch is confirmed via the Microsoft MSRC advisory.
