Local privilege escalation in Microsoft Windows Win32K lets an authenticated low-privileged user corrupt kernel heap memory (CWE-122) to gain SYSTEM-level control across virtually all supported Windows client and server builds. Publicly available exploit code exists, though CISA SSVC assessed exploitation status as none and EPSS is modest (0.37%, 29th percentile), indicating a serious but not yet mass-exploited weakness. A vendor patch is available via Microsoft's update guide, making prompt patching the clear priority.
Local privilege escalation in the Windows Print Spooler Components affects Windows 10 (1809, 21H2, 22H2), Windows 11 (24H2, 25H2, 26H1), and Windows Server 2019/2022/2025, where a heap-based buffer overflow (CWE-122) lets an already-authenticated local user corrupt heap memory in a Spooler component and gain SYSTEM-level privileges. Exploitation requires low-privilege local access (CVSS AV:L/PR:L) with no user interaction, yielding full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV.
Privilege escalation in the Windows Netlogon service allows an authenticated network attacker to gain elevated privileges by triggering a use-after-free (CWE-416) memory-corruption condition. The flaw affects a broad range of supported Windows client and server builds, from Windows Server 2012 through Windows 11 25H2/26H1 and Windows Server 2025, and was reported by Microsoft. There is no public exploit identified at time of analysis and CISA SSVC currently rates exploitation as none, with a low EPSS of 0.62%.

Local privilege escalation in the Microsoft Windows Kernel lets an already-authenticated attacker corrupt heap memory to gain SYSTEM-level control across Windows 10 (1809/21H2/22H2), Windows 11 (24H2/25H2/26H1), and Windows Server 2019/2022/2025. The CVSS 7.8 (AV:L/PR:L) rating reflects that low-privileged code execution is a prerequisite; there is no public exploit identified at time of analysis, but Microsoft has released a patch. This is a classic post-exploitation escalation primitive rather than an initial-access vector.
Local tampering in Windows DNS via improper access control (CWE-284) allows a low-privilege authenticated local user to manipulate DNS configuration or records across a broad range of Windows 10, Windows 11, and Windows Server releases. The CVSS vector (AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L) confirms exploitation requires only a valid local account with no elevated privileges, yielding high integrity impact with minimal availability disruption and no direct confidentiality exposure. No public exploit code or CISA KEV listing has been identified at time of analysis, but the 'Authentication Bypass' advisory tag suggests DNS tampering may enable downstream bypass of authentication mechanisms dependent on DNS resolution, potentially amplifying the effective impact beyond the raw CVSS score.
Local privilege escalation to code execution in the Windows NTFS driver affects a broad range of supported Windows client and server builds, from Windows 10 1607 and Server 2012 through Windows 11 26H1 and Server 2025.

CVSS 3.1 scores this 7.5 (C:H/I:N/A:N), reflecting a pure confidentiality breach with no integrity or availability impact. There is no public exploit identified at time of analysis, and SSVC rates exploitation as none with partial technical impact; EPSS is a modest 0.58% (44th percentile).
Windows Media in Microsoft Windows exposes sensitive information to locally authenticated standard users, allowing disclosure of data the attacker is not authorized to access. Affected platforms span Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 R2 through Server 2025, representing a very broad installed base. No public exploit code has been identified and EPSS at 0.36% (28th percentile) reflects low opportunistic interest, though the local-access requirement is a weaker barrier in shared-access environments such as Remote Desktop Services or VDI deployments.
Denial of service in Microsoft Active Directory Federation Services (AD FS) allows a remote, unauthenticated attacker to crash the service by sending crafted network input that overflows a stack buffer (CWE-121). Because AD FS commonly fronts single sign-on for Microsoft 365, Azure AD, and federated web applications, an outage cascades into loss of authentication for every relying-party application. There is no public exploit identified at time of analysis and the flaw is not in CISA KEV; a Microsoft patch is available, and the CVSS 3.1 score is 7.5 (availability-only impact).
Remote code execution in Microsoft's Remote Desktop Client (the RDP client, mstsc.exe, shipped across Windows 10, Windows 11, and Windows Server 2012 through 2025) allows an unauthorized attacker to run arbitrary code over the network by triggering a use-after-free memory-corruption condition. Exploitation requires the victim to connect to an attacker-controlled or compromised RDP endpoint (UI:R), after which the malicious server can corrupt client-side memory to achieve full code execution. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV; a vendor patch is available from Microsoft.
Local code execution in Microsoft Windows' Resilient File System (ReFS) driver lets an unauthorized attacker run arbitrary code by inducing a victim to mount or open a maliciously crafted ReFS volume (CVE-2026-50362).

Successful exploitation yields total loss of confidentiality, integrity, and availability on the host, though there is no public exploit identified at time of analysis and CISA's SSVC framework rates exploitation as 'none' and non-automatable. EPSS is low (0.29%, 21st percentile), consistent with a locally-scoped bug that requires prior code execution rather than a remotely wormable threat.
Local privilege escalation in the Microsoft Windows Kernel (CVE-2026-50377) lets an already-authenticated low-privileged attacker read memory outside intended bounds and leverage it to gain SYSTEM-level rights across a broad range of Windows 10, Windows 11, and Windows Server builds. Microsoft has released patches and rates it 7.8 (High); there is no public exploit identified at time of analysis, EPSS is low at 0.40% (32th percentile), and CISA SSVC records exploitation as none. It is a strong second-stage escalation primitive for attackers who already have a foothold, but not a remotely reachable, wormable threat.
Local code execution in Microsoft's Resilient File System (ReFS) driver lets an already-authenticated, low-privileged user on affected Windows 10, Windows 11, and Windows Server 2016–2025 systems escalate to code execution through a numeric truncation flaw (CWE-197). No public exploit has been identified at time of analysis, and it is not on CISA KEV, but Microsoft has released a patch. Note a data conflict: the description states code execution and the CVSS carries C:H/I:H/A:H, yet the vendor tags label it 'Information Disclosure' — the CVSS-backed local elevation-of-privilege reading is treated as authoritative here.
Privilege escalation via a heap-based buffer overflow (CWE-122) in the Windows Remote Desktop Client lets an unauthorized network attacker corrupt heap memory and gain total control of the target host. The flaw affects the built-in RDP client across the entire supported Windows line, from Windows 10 1607 and Windows Server 2012 through Windows 11 26H1 and Windows Server 2025. Microsoft has shipped patches; there is no public exploit identified at time of analysis and it is not in CISA KEV, though CISA's SSVC assessment rates the flaw automatable with total technical impact.
Local privilege escalation in the Windows Ancillary Function Driver for WinSock (afd.sys) allows an authenticated low-privileged attacker to gain SYSTEM-level control by triggering a use-after-free condition in the kernel networking driver. The flaw affects a broad range of Windows client and server releases from Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 through Server 2025. Reported by Microsoft with a vendor patch available; no public exploit identified at time of analysis, and EPSS exploitation probability is low (0.31%).
