There is no public exploit identified at time of analysis, and the CVE is not listed in CISA KEV.

Exposure of sensitive information to an unauthorized actor in Windows File Explorer allows an authorized attacker to disclose information locally.

Use of uninitialized resource in Windows File Explorer allows an authorized attacker to disclose information locally.

Windows Audio Service on multiple Windows desktop and server versions improperly exposes sensitive information to locally authenticated standard users, enabling information disclosure without requiring elevated privileges. Affecting Windows 10 1809 through Windows 11 26H1 and Windows Server 2019 (with Server 2022 and 2025 referenced in tags), the flaw is exploitable post-foothold by any low-privileged local account, making it a realistic post-exploitation pivot rather than an initial access vector. No public exploit code has been identified at time of analysis, and a vendor-released patch is confirmed available via the Microsoft Security Response Center.

Exposure of sensitive information to an unauthorized actor in Windows File Explorer allows an authorized attacker to disclose information locally.

Local code execution in Microsoft Windows NTFS driver allows an authenticated attacker to run arbitrary code by triggering a heap-based buffer overflow (CWE-122) after inducing user interaction. The flaw affects a broad range of Windows client and server releases, from Windows 10 1607 and Windows Server 2012 through Windows 11 26H1 and Windows Server 2025. It was reported by Microsoft, a vendor patch is available, and there is no public exploit identified at time of analysis.

Local privilege escalation in Microsoft Windows Narrator (the built-in screen reader) arises from improper neutralization of special elements in its Braille support component, allowing an already-authenticated local attacker (PR:L) to inject and execute OS commands that run with elevated privileges. All supported Windows client and server builds from Windows 10 1809 through Windows 11 26H1 and Windows Server 2019-2025 are affected, and Microsoft has released a patch. There is no public exploit identified at time of analysis and the CVE is not in CISA KEV, so exploitation is not confirmed as active.

Out-of-bounds read in Windows Kernel allows an authorized attacker to bypass a security feature locally.

Local code execution in Microsoft Windows Media Foundation lets an attacker run arbitrary code in the context of the victim after luring them to open a maliciously crafted media file. The flaw (CVE-2026-58610, CWE-122 heap-based buffer overflow) affects a broad range of Windows client and server releases from Windows 10 1607 through Windows 11 26H1 and Windows Server 2016 through 2025. CVSS is 7.8 (AV:L/AC:L/PR:N/UI:R) with full confidentiality, integrity, and availability impact; there is no public exploit identified at time of analysis and it is not on CISA KEV.

Local code execution in the Microsoft Graphics Component affects a broad range of supported Windows client and server releases (Windows 10 1607 through Windows 11 26H1, and Windows Server 2012 through Server 2025). An attacker who convinces a user to open a specially crafted file or content triggers an out-of-bounds read (CWE-125) that Microsoft rates as enabling code execution with high confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; exploitation requires local access plus user interaction, making it a standard patch-cycle priority rather than an emergency.

Network code execution in the Windows Print Spooler service allows an authenticated attacker to win a synchronization race and run arbitrary code across a broad range of Windows client and server builds (Windows 10 1607 through Windows 11 26H1, and Windows Server 2012 through 2025). Microsoft rates it CVSS 8.8 with high confidentiality, integrity, and availability impact; a vendor patch is available, and there is no public exploit identified at time of analysis. Note that the CVE description and CVSS indicate remote code execution while the source tags label it 'Information Disclosure' — a discrepancy defenders should verify against the MSRC advisory.

Local privilege escalation in the Windows Virtual Hard Disk (VHD) Miniport Driver lets an authenticated low-privileged user corrupt kernel heap memory and gain SYSTEM-level control. The flaw (CWE-122 heap-based buffer overflow, CVSS 7.8) affects a broad range of Windows 10, Windows 11, and Windows Server builds and was reported by Microsoft. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Local privilege escalation in Microsoft Windows arises from a use-after-free flaw (CWE-416) in the Windows Storage component, affecting Windows 10 (1809, 21H2, 22H2), Windows 11 (24H2, 25H2, 26H1), and Windows Server 2019/2022/2025. An authorized attacker who already has low-level access to a machine can trigger the freed-memory reuse to elevate to higher privileges (CVSS 7.0, high attack complexity). Microsoft has released a patch; there is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.

Out-of-bounds read in Windows RDP allows an unauthorized attacker to disclose information over a network.

Null pointer dereference in Windows Active Directory Domain Services (AD DS) enables a low-privileged authenticated attacker to crash the service remotely, causing denial of service across the affected domain. The flaw spans a wide range of Windows client and server releases, from Windows 10 version 1607 through Windows 11 version 26H1 and Windows Server 2012 through 2025. No public exploit code has been identified and this vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog at time of analysis, though the network-accessible attack surface and low privilege requirement lower the bar for abuse in environments with broad domain user access.

Untrusted search path in Microsoft XML allows an unauthorized attacker to bypass a security feature with a physical attack.
