CVE-2026-58541 HIGH PATCH Exploit Unlikely This Week

Local privilege escalation in the Windows Desktop Window Manager (DWM) Core Library allows an authenticated attacker to gain SYSTEM-level privileges by triggering a type-confusion (CWE-843) condition. The flaw affects a broad range of supported Windows client and server releases from Windows 10 1607 through Windows 11 26H1 and Windows Server 2016 through 2025. Reported internally by Microsoft with a vendor patch available; no public exploit identified at time of analysis.

CVE-2026-57108 HIGH PATCH Exploit Unlikely This Week

Denial of service in Microsoft .NET (versions 8.0, 9.0, and 10.0) allows a remote, unauthenticated attacker to crash or hang affected applications by triggering a type-confusion condition (CWE-843) over the network. The flaw was reported by Microsoft and a vendor patch is available via MSRC; there is no public exploit identified at time of analysis. The CVSS vector limits impact strictly to availability (A:H, C:N/I:N), meaning it is a service-disruption bug rather than a code-execution or data-exposure issue despite tag noise suggesting otherwise.

CVE-2026-54116 MEDIUM PATCH Exploit Unlikely This Month

Type confusion (CWE-843) in Microsoft SQL Server 2025 enables authenticated, low-privileged network attackers to disclose sensitive server-side information. The CVSS vector (AV:N/PR:L/C:H) confirms that any authorized database user - regardless of their data access permissions - can potentially trigger the flaw remotely with no user interaction required. No public exploit code or CISA KEV listing exists at time of analysis, but the high confidentiality impact and low access complexity make patching a meaningful priority for organizations running SQL Server 2025.

Local code execution in Microsoft Excel (Microsoft 365 Apps, Office 2019/LTSC 2021/2024, Office for Mac, and Office Online Server) arises from a type-confusion flaw (CWE-843) in how Excel parses spreadsheet content. An attacker who convinces a victim to open a malicious workbook can run arbitrary code in the context of the current user, gaining high confidentiality, integrity, and availability impact. Reported by Microsoft with a patch available; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Local arbitrary code execution in Microsoft Office (2016, 2019, LTSC 2021/2024, Microsoft 365 Apps for Enterprise, and Office for Mac 2021/2024) arises from a type-confusion flaw (CWE-843) that lets an attacker run code in the context of the current user when a victim opens a crafted file. The CVSS 3.1 base score is 7.8 (AV:L/AC:L/PR:N/UI:R) reflecting local vector with required user interaction and high impact to confidentiality, integrity, and availability. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but a vendor patch is available via MSRC.

The CVSS 3.1 score is 7.8 (High) with the local vector reflecting file-open exploitation rather than remote-network access, and success requires user interaction. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.

CVE-2026-50686 HIGH PATCH Exploit Unlikely This Week

Remote code execution in Microsoft Windows OLE (Object Linking and Embedding) allows an unauthorized network attacker to run arbitrary code by triggering a type-confusion condition (CWE-843) in the OLE component. The flaw affects a broad range of client and server SKUs from Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 R2 through Server 2025, and carries a CVSS 8.1 (High) rating. No privileges or authentication are required per the CVSS vector, though the high attack complexity (AC:H) means exploitation depends on winning a specific timing or memory-state condition; there is no public exploit identified at time of analysis and it is not on CISA KEV.

The flaw affects a broad range of currently-supported Windows client and server builds, from Windows 10 1607 through Windows 11 26H1 and Windows Server 2016 through 2025. Microsoft has released a patch; there is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV.

Local privilege escalation in the Windows Kernel (CVE-2026-50390) lets an already-authenticated attacker abuse a type-confusion condition to run code with elevated (SYSTEM-level) privileges on affected Windows client and server builds ranging from Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 through Server 2025. Microsoft has shipped a fix and there is no public exploit identified at time of analysis, but as a kernel EoP it is a classic second-stage building block for turning a foothold into full host compromise. CVSS is 7.0 (High), reflecting high attack complexity but full confidentiality, integrity, and availability impact once triggered.
