Microsoft has released patches across all affected branches; no public exploit code or CISA KEV listing has been identified at time of analysis.
Use-after-free in Windows Embedded Mode Service allows a locally authenticated attacker with low privileges to escalate to SYSTEM-level access across virtually all supported Windows versions. The memory corruption occurs when the service accesses a previously freed object, enabling an attacker to manipulate heap layout and execute code in a privileged context. No public exploit or active exploitation (KEV) has been identified; Microsoft has released patches via Windows Update, and the AC:H rating reflects the timing-dependent race-condition exploitation typical of UAF primitives.
Privilege escalation in the Windows USB Video Driver (Windows 11 24H2/25H2/26H1 and Windows Server 2025) is enabled by a use-after-free memory corruption flaw in a kernel-mode driver component. A local attacker holding a standard user account can exploit the UAF condition to achieve ring-0 code execution, yielding complete confidentiality, integrity, and availability compromise of the affected system. Microsoft has released patches; no public exploit has been identified at time of analysis and the CVE does not appear in CISA KEV.

No active exploitation is confirmed (absent from CISA KEV) and no public exploit code has been identified, but the breadth of affected Windows versions - from Windows 10 1809 through Windows 11 26H1 and Windows Server 2019 through 2025 - makes this a meaningful patch priority for multi-user and enterprise Windows environments.
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.
Use-after-free (CWE-416) in the Windows Kernel enables a low-privileged local attacker to escalate privileges to SYSTEM on a broad range of Windows client and server releases. The CVSS vector (AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H) indicates full confidentiality, integrity, and availability compromise once triggered, though the high attack complexity (AC:H) implies a race-condition or specific timing requirement that raises the bar for reliable exploitation. Microsoft has released patches for all affected versions; no public exploit or CISA KEV listing has been identified at time of analysis.
Local privilege escalation in Windows Win32K allows an authenticated low-privileged user to gain SYSTEM-level access across virtually all supported and legacy Windows versions. The flaw stems from incorrect authorization checks (CWE-863) in the Win32K kernel-mode subsystem, enabling a local attacker to bypass privilege boundaries with no user interaction required. No public exploit has been identified and CISA's SSVC assessment rates exploitation status as none, though technical impact is rated total - patch deployment is nonetheless warranted given the ubiquity of the affected platform and the historical weaponization of Win32K LPE bugs in targeted intrusion chains.
Local privilege escalation in the Windows Resilient File System (ReFS) Deduplication Service allows a low-privileged authenticated attacker to gain full system control via improper symlink/junction resolution (CWE-59). Affected platforms include Windows Server 2025 and Windows 11 versions 24H2, 25H2, and 26H1. Exploitation requires local access and a race condition (AC:H), making this a targeted rather than opportunistic threat; no public exploit or CISA KEV listing exists at time of analysis.
Local privilege escalation in the Windows Kernel across virtually all supported Windows releases exploits a time-of-check time-of-use (TOCTOU) race condition (CWE-367) to elevate from low-privilege user to SYSTEM.

Local privilege escalation in the Windows USB Audio Class kernel driver (usbaudio.sys) is possible through a time-of-check time-of-use (TOCTOU) race condition. An authenticated local attacker with low privileges can win the race window to escalate to higher privilege levels, achieving full confidentiality, integrity, and availability impact on the affected system. No public exploit code has been identified at time of analysis, but the breadth of affected Windows versions — spanning Windows 10 1607 through Windows 11 26H2 and Windows Server 2012 through 2025 — gives this vulnerability a large attack surface.
Local privilege escalation in Windows Device Association Service exposes all supported Windows client and server editions to full system compromise by a low-privileged local attacker. The root cause is a use-after-free triggered through a race condition (CWE-362): concurrent access to a shared resource in the Device Association Service allows a freed memory object to be reused, enabling controlled code execution in a higher-privilege context. No public exploit or CISA KEV listing is present at time of analysis, but the breadth of affected versions - spanning Windows 10 through Windows 11 26H1 and Windows Server 2012 R2 through 2025 - makes this a high-priority patch for any environment with untrusted local users.

Microsoft has released patches as part of a security update cycle; no public exploit or CISA KEV entry has been identified at time of analysis.
Privilege escalation and local code execution affect the OpenTelemetry.Resources.Host NuGet package (opentelemetry-dotnet-contrib) on macOS prior to version 1.16.0-beta.2. The host.id resource attribute detector invokes sh and ioreg using bare names resolved through the PATH environment variable rather than absolute paths, allowing a local attacker with fewer privileges than the host application to substitute malicious binaries and execute arbitrary code in the application's security context. No public exploit has been identified at time of analysis; Linux and Windows hosts are explicitly unaffected.
Unsigned code execution on Siemens Reyrolle 7SR5 protection relays (all firmware versions before V2.70) is possible when an attacker with physical access triggers a special maintenance boot mode via a hardware key sequence. In this mode the relay unconditionally downloads and executes code from a network server with no cryptographic signature or integrity verification, fully satisfying CWE-494. No public exploit code has been identified and the vulnerability is not listed in the CISA KEV catalog; risk is bounded by the physical-access prerequisite but is severe once that barrier is crossed in OT substation environments.
Local privilege escalation in the Android common kernel's alloc.c memory allocation functions allows a low-privileged local user to gain full read/write access to kernel memory via a race condition. Multiple functions in alloc.c are affected, with successful exploitation yielding complete confidentiality, integrity, and availability compromise of the device. The vulnerability requires no user interaction and no elevated privileges beyond an existing local shell; Google addressed it in the September 2026 Android Security Bulletin with a patch committed to the Android common kernel repository.

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 Win32K kernel graphics driver affects every supported Windows release from Server 2012 through Windows 11 26H1, allowing a low-privileged authenticated local user to gain SYSTEM-level access. The root cause is a buffer over-read (CWE-126) in the Win32K subsystem: out-of-bounds memory reads in kernel context can expose critical kernel data structures - including address layout information - that enable a subsequent control-flow hijack to full SYSTEM privileges. No public exploit has been identified at time of analysis and the CVE is not listed in CISA KEV, though Microsoft has issued patched cumulative updates for all affected product lines.
