Privilege escalation in Windows 11 Secure Kernel Mode (Virtualization-Based Security / VTL1) allows a locally authorized attacker with high privileges to cross the VBS isolation boundary and achieve full C:H/I:H/A:H impact on the Secure Kernel context. The root cause is CWE-822 (Untrusted Pointer Dereference): attacker-controlled pointer values are dereferenced without validation inside Secure Kernel Mode, enabling code execution at the VTL1 trust level. No public exploit code or CISA KEV listing has been identified at time of analysis; a vendor patch is available for Windows 11 26H1.
Local privilege escalation in Windows Virtualization-Based Security (VBS) Enclave exposes authenticated local attackers to full system compromise via an untrusted pointer dereference (CWE-822). Affected platforms include Windows 11 versions 23H2 through 26H1 and Windows Server 2025 in both standard and Server Core configurations, with Microsoft confirming a patch is available. No public exploit code or active exploitation has been identified at time of analysis, but the low attack complexity (AC:L) makes post-access escalation straightforward for any attacker holding a standard local session.
Guest-to-host code execution in Windows Hyper-V affects authorized guest VM users who can trigger an untrusted pointer dereference (CWE-822) to execute code in the hypervisor context, effectively escaping the VM sandbox. The CVSS scope-change metric (S:C) confirms this is a privilege escalation from guest to host, making it a hypervisor escape with full High C/I/A impact on the underlying host. Affected platforms span Windows Server 2022 and 2025 and multiple Windows 11 release channels (23H2 through 25H2). No public exploit or CISA KEV listing identified at time of analysis; vendor patch is available.
Remote code execution in Windows Failover Cluster allows an unauthenticated network attacker to fully compromise affected Windows Server systems by triggering an untrusted pointer dereference (CWE-822) over the network. Affected deployments span Windows Server 2019, 2022, and 2025 (including Server Core variants) and Windows 10 Version 1809, with vendor-released patches available via Microsoft Security Response Center. No public exploit has been identified at time of analysis, but the full C:H/I:H/A:H impact delivered without authentication makes this a high-priority patching target for any organization running Windows Server clustering.
Privilege escalation in the Windows Kernel Streaming WOW Thunk Service Driver exposes multiple Windows 10, Windows 11, and Windows Server 2025 builds to local SYSTEM-level compromise through CWE-822 untrusted pointer dereference. A low-privileged local attacker can craft an IOCTL that causes the driver to dereference an attacker-controlled pointer value in kernel context, yielding full system takeover. Microsoft has released patched builds across all affected versions; no public exploit code or CISA KEV listing has been identified at time of analysis.
Local privilege escalation in Windows Advanced Local Procedure Call (ALPC) allows an attacker already holding high administrative privileges to further escalate to kernel-level or system-level access via untrusted pointer dereference (CWE-822). The vulnerability affects a wide sweep of Windows releases - from Windows 10 version 1809 through Windows 11 26H1 and Windows Server 2019 through Server 2025 - and is confirmed patched by Microsoft. The CVSS scope-change flag (S:C) indicates the exploit crosses privilege boundaries beyond the initially compromised component, yielding full confidentiality, integrity, and availability impact on subordinate system resources. No public exploit or active exploitation (CISA KEV) has been identified at time of analysis.
Local privilege escalation in Windows Secure Kernel Mode exploits an untrusted pointer dereference (CWE-822) to allow a low-privileged local attacker to elevate to full kernel-level control across a broad range of Windows 10, 11, and Server releases. The Secure Kernel Mode (SKM) context - part of Windows Virtualization-Based Security (VBS) operating at Virtual Trust Level 1 (VTL1) - means successful exploitation bypasses standard OS-kernel isolation, making this structurally more severe than a conventional LPE. No public exploit identified at time of analysis; vendor-released patches are available via Microsoft's July 2026 security update cycle.
Privilege escalation in Windows Remote Desktop Services exploits an untrusted pointer dereference (CWE-822) to allow a locally authenticated low-privileged attacker to gain full system control (C:H/I:H/A:H). The flaw affects a broad swath of Windows versions from Server 2012 through Server 2025 and Windows 10/11 across multiple feature update branches. No public exploit code or active exploitation has been identified at time of analysis, but Microsoft has released patches via the standard update cycle.
Remote code execution in Microsoft SQL Server allows an authenticated low-privilege attacker to exploit an untrusted pointer dereference (CWE-822) over the network, achieving full compromise of the host with scope change beyond the database engine. Affected instances span SQL Server 2019, 2022, and 2025 across both Cumulative Update and GDR servicing branches. No public exploit code or CISA KEV listing has been identified at time of analysis, though the high complexity rating (AC:H) and scope change (S:C) signal a serious memory corruption primitive when conditions are met.
Untrusted pointer dereference (CWE-822) in IBM AIX's Virtual SCSI (vSCSI) initiator driver allows a low-privileged local user within a client LPAR to trigger kernel memory corruption, with outcomes spanning denial of service, privilege escalation, or full compromise of the client LPAR kernel. Affecting IBM AIX 7.2 and 7.3 and PowerVM VIOS 4.1, the CVSS 3.1 score of 8.8 with scope change (S:C) reflects the cross-LPAR isolation risk inherent in PowerVM virtualization environments where VIOS mediates I/O for multiple tenants. No public exploit code or active exploitation has been identified at time of analysis; however, CISA's SSVC framework rates the technical impact as total, meaning successful exploitation fully undermines the security of the affected system.
