The vulnerability spans Windows 10, Windows 11, and Windows Server 2019 through 2025, representing an extraordinarily broad attack surface across enterprise and consumer environments. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA KEV, though the CVSS 7.0 rating reflects realistic difficulty from high attack complexity (AC:H).

Use-after-free in the Windows Hello authentication subsystem on Windows 10 and 11 allows a locally authenticated, low-privileged user to escalate privileges beyond their security boundary. The CVSS scope-change indicator (S:C) confirms that successful exploitation crosses into a more privileged security context - likely SYSTEM or kernel-level - with full confidentiality, integrity, and availability impact. Vendor patch is available via Microsoft's update guide; no public exploit code has been identified at time of analysis.

Privilege escalation in Windows 11 Version 23H2 and Windows Server 2025 (including Server Core) is possible through a use-after-free in the Desktop Window Manager (DWM) Core Library, which an attacker who already holds an authenticated low-privileged foothold can trigger over a network-facing code path without user interaction. Successful exploitation yields high confidentiality, integrity, and availability impact within the DWM security context, but the CVSS AC:H rating and CISA SSVC determination (Exploitation: none, Automatable: no) reflect a timing-sensitive race and heap-grooming requirement that makes reliable weaponization difficult. Microsoft has released a vendor patch, and no public exploit code or active exploitation has been identified at time of analysis (EPSS 0.52%, 43rd percentile).

Use-after-free in Microsoft Office PowerPoint enables remote code execution when a victim opens a specially crafted PowerPoint document. The vulnerability affects PowerPoint 2016, 2019, Office LTSC 2021, LTSC 2024, Microsoft 365 Apps for Enterprise, and Office for Mac across multiple build versions, spanning virtually the entire active Office install base. Vendor patches have been released; no public exploit or CISA KEV listing has been identified at time of analysis.

Privilege escalation in the Windows TCP/IP stack lets an attacker who already holds low-privileged authorized access on a reachable host trigger a kernel use-after-free and elevate to SYSTEM, with full compromise of confidentiality, integrity, and availability on the affected machine. The flaw affects a very broad install base - Windows 10 (1607, 1809, 21H2, 22H2), Windows 11 (23H2, 24H2, 25H2, 26H1) and Windows Server 2012 through 2025 - but exploitation is constrained by high attack complexity, since the attacker must reliably win a memory reclamation race in kernel space; Microsoft has shipped fixes and there is no confirmed active exploitation (not in CISA KEV; SSVC exploitation: none) and no public exploit identified at time of analysis. EPSS is low at 0.52% (43rd percentile), so this is best handled as a routine but high-priority patch-cycle item rather than an emergency.

Privilege escalation in the Microsoft Windows TCP/IP kernel stack lets an authenticated attacker who already holds low privileges on a reachable host corrupt kernel memory over the network and escalate to SYSTEM, with high impact to confidentiality, integrity and availability. Exploitation hinges on winning a use-after-free race in tcpip.sys, which is why the vector carries AC:H and CISA SSVC rates the issue as not automatable with no observed exploitation; EPSS is 0.65 percent (49th percentile), and no public exploit was identified at time of analysis. All in-support Windows 10, Windows 11, Windows Server 2019, 2022 and 2025 builds below the vendor's fixed revisions are affected, and Microsoft has released patches.

Privilege escalation in Windows Hello on Windows 11 allows a low-privileged local attacker to gain SYSTEM-level or kernel-level access via a use-after-free memory corruption flaw (CWE-416). Affected builds span all currently supported Windows 11 feature releases (23H2, 24H2, 25H2, and 26H1) prior to Microsoft's July 2026 security update. No public exploit code has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but the low complexity and absence of required user interaction make this a high-value second-stage escalation primitive.

Local privilege escalation in the Windows Broadcast DVR User Service allows a low-privileged authenticated attacker to gain full system control via a use-after-free memory corruption bug. The vulnerability affects a wide swath of Windows 10, Windows 11, and Windows Server 2016/2019 builds, with Microsoft releasing patches across all affected branches. No public exploit code or active exploitation has been identified at time of analysis, but local LPE vulnerabilities of this class are routinely incorporated into post-exploitation toolchains following initial access.

Remote code execution in the Microsoft Windows DNS Server role (across Windows Server 2012 through 2025 and Windows 10 1607/1809) stems from a use-after-free that an unauthenticated attacker can trigger over the network, per CVSS PR:N/UI:N. Microsoft rates it 9.8 (critical) with full confidentiality, integrity, and availability impact, and a vendor patch is available. No public exploit has been identified at time of analysis and it is not listed in CISA KEV.

Remote code execution in the Windows Key Distribution Center (KDC) - the Kerberos authentication service running on every Active Directory domain controller - allows a low-privileged authenticated network attacker to execute arbitrary code via a use-after-free memory corruption flaw (CWE-416). Every currently-supported Windows Server release from Server 2012 through Server 2025 is affected, spanning the full breadth of enterprise Active Directory infrastructure. Microsoft has released patches with exact build-level thresholds per platform; no public exploit code and no CISA KEV listing are identified at time of analysis.

Use-after-free in the Windows Device Association Service enables a local low-privileged attacker to escalate to full system-level privileges across a wide range of Windows 10, Windows 11, and Windows Server releases. The vulnerability stems from improper memory management in the service responsible for pairing devices, where a freed memory region can be reused to redirect execution. Microsoft has released patches addressing all affected builds; no public exploit or CISA KEV listing is recorded at time of analysis, though the high-complexity (AC:H) requirement means reliable exploitation demands careful timing or race-condition abuse.

Privilege escalation via use-after-free (CWE-416) in the Windows Web Platform Storage component affects Windows 10, 11, and multiple Windows Server releases. An authenticated local user with standard (low) privileges can exploit a race condition in memory management to achieve full local system compromise - gaining high confidentiality, integrity, and availability impact. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, but the breadth of affected Windows versions across the enterprise install base makes patch prioritization essential.

Privilege escalation in the Windows Win32K kernel component allows an attacker who already holds low-privileged execution on a target host (PR:L) to corrupt kernel memory and escalate to SYSTEM-level privileges. Microsoft rates the flaw CVSS 7.5 (HIGH) with vector AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H, although our assessment reads the practical attack vector as local (AV:L); in either reading the precondition is existing code execution on the box, making this a post-compromise escalation primitive rather than a remotely reachable entry point, and the high attack complexity means a race condition or specific heap/object state must be won reliably. Affected are unpatched Windows 10 (1607 through 22H2), Windows 11 (23H2 through 26H1) and Windows Server 2012 through 2025 builds below the fixed build numbers published by Microsoft; there is no public exploit identified at time of analysis, no CISA KEV listing, and EPSS is low at 0.44% (37th percentile), so near-term exploitation risk is driven by targeted, post-access actors rather than mass scanning.

Use-after-free (UAF) in the Windows Device Association Broker service enables a local, low-privileged authenticated attacker to escalate privileges to SYSTEM or higher on a broad range of Windows 10, Windows 11, and Windows Server releases. The vulnerability (CWE-416) is consistent with a race condition in the Broker's memory management, as reflected by the AC:H metric, and exploitation yields full confidentiality, integrity, and availability impact on the local system. No public exploit code has been identified at time of analysis, but Microsoft has released patches across all affected build streams.

Use-after-free memory corruption in Windows Audio Service enables local privilege escalation across the full Windows ecosystem, from Windows 10 1607 through Windows 11 26H1 and all supported Windows Server releases from 2012 through 2025. The CVSS vector (AV:L/AC:H/PR:L) confirms a locally authenticated attacker must navigate high-complexity exploit conditions - likely a race or timing attack on the audio service's memory lifecycle - before achieving full C:H/I:H/A:H impact, including arbitrary code execution at elevated privilege. No public exploit code has been identified at time of analysis, but Microsoft has released patches for all listed affected builds.

Remote code execution in Microsoft Office PowerPoint stems from a use-after-free memory corruption flaw (CWE-416) that enables network-based attackers to execute arbitrary code when a victim opens a crafted presentation file.

Remote code execution in Microsoft Office via a use-after-free (CWE-416) memory corruption flaw allows a network-adjacent or remote attacker to execute arbitrary code on the victim's machine. The attack is client-side: the attacker delivers a maliciously crafted Office document, which when opened by the user triggers the UAF condition. Affected products span the full Office family including LTSC 2021, LTSC 2024, Office 2019, Microsoft 365 Apps for Enterprise, and Mac variants; a vendor patch is available.

Use-after-free in the Windows Image Acquisition (WIA) subsystem enables an authorized local attacker to escalate privileges on every supported Windows release, from Server 2012 to Windows 11 26H1. The CVSS vector (AV:L/AC:H/PR:L) places exploitation difficulty above average - a low-privileged user must trigger a race condition or specific memory-reuse timing within the WIA service - but a successful exploit yields full C:H/I:H/A:H impact, effectively granting SYSTEM-level control. No public exploit has been identified at time of analysis, and Microsoft has released patched builds across all affected version branches.

Local privilege escalation in the Windows Virtual Hard Disk (VHD) Miniport Driver allows a low-privileged local attacker to gain full SYSTEM-level control across a broad range of Windows 10, Windows 11, and Windows Server versions. The flaw stems from a use-after-free (CWE-416) condition in a kernel-mode driver, with high attack complexity indicating a likely race condition or specific timing requirement. Microsoft has released patches; no public exploit code or CISA KEV listing has been identified at time of analysis.

Remote code execution in Windows Deployment Services (WDS) exploits a use-after-free memory corruption flaw, allowing an unauthenticated network attacker to execute arbitrary code on the WDS server.

An authenticated local attacker who triggers the race-condition-sensitive bug can achieve full system compromise with C:H/I:H/A:H impact, yielding effective SYSTEM-level control. No public exploit or CISA KEV listing has been identified at time of analysis; Microsoft has confirmed and patched the issue across all affected builds as documented in EUVD-2026-73549.

Use-after-free in Windows Install Service permits local privilege escalation to SYSTEM on all actively supported Windows platforms. An authorized low-privilege local user can exploit a freed memory object in the service to corrupt heap structures and gain full control (C:H/I:H/A:H). The high attack complexity (AC:H) signals a race condition or specific timing requirement, tempering but not eliminating real-world risk; no public exploit or CISA KEV listing is identified at time of analysis.

Privilege escalation in the Windows PrintWorkflowUserSvc (Print Workflow User Service) component of Microsoft's modern print stack lets a low-privileged, authenticated attacker elevate to a higher-integrity context by winning a use-after-free race inside the service (CWE-416). Unpatched Windows 10 (1809, 21H2, 22H2), Windows 11 (23H2, 24H2, 25H2, 26H1) and Windows Server 2019/2022/2025 systems - including Server Core installations - are exposed, and the service is present by default. Scoring CVSS 7.5 with AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H, the bug is network-reachable but requires careful heap grooming and no user interaction; there is no public exploit code identified at time of analysis (EPSS 0.57%, 45th percentile; CISA SSVC exploitation status "none"), and vendor patches are available.

Local privilege escalation to SYSTEM in the Windows Search Component (WSearch) affects virtually every supported Windows client and server platform from Windows Server 2012 through Windows Server 2025 and Windows 10/11 across all major release branches. The vulnerability stems from a use-after-free (CWE-416) memory corruption flaw that an attacker with a standard user account can trigger to execute code at elevated privilege. The high attack complexity (AC:H) in the CVSS vector indicates exploitation likely requires precise timing consistent with a race condition; no public exploit code or CISA KEV listing has been identified at time of analysis, but a vendor patch is available.
