An attacker operating a malicious SMB server can trigger a freed-memory dereference during client-side protocol processing, yielding arbitrary code execution with a full C:H/I:H/A:H impact triad. Microsoft has released cumulative updates addressing the flaw; no CISA KEV listing or public proof-of-concept exploit has been identified at time of analysis.
Windows Shell's link-resolution logic fails to safely handle symbolic or hard links before granting file access, enabling a remote unauthenticated attacker to perform network-based spoofing against a victim who interacts with a crafted payload. The flaw (CWE-59) spans the full current Windows ecosystem - from Server 2012 R2 through Windows 11 26H2 and Server 2025 - and can yield both confidentiality and integrity compromise (C:H/I:H). No public exploit or CISA KEV listing has been identified at time of analysis, but user interaction (UI:R) is the sole barrier to exploitation.
Use-after-free in the Windows Ancillary Function Driver for WinSock (afd.sys) allows network-reachable unauthenticated attackers to elevate privileges to SYSTEM level on affected Windows hosts. The vulnerability spans a broad surface - every supported Windows release from Server 2012 through Windows 11 25H2 and Server 2025 is confirmed affected. SSVC rates exploitation status as none and the attack as non-automatable, but technical impact is total, meaning successful exploitation yields full system compromise. No public exploit or KEV listing has been identified at time of analysis.
Heap-based buffer overflow in the Windows Link Layer Topology Discovery Protocol (LLTD) implementation enables unauthenticated attackers to execute arbitrary code on affected Windows systems via crafted network-layer frames. The flaw (CWE-122) spans nearly the entire supported Windows ecosystem - from Windows 10 through Windows 11 and from Windows Server 2012 through Server 2025.

Remote code execution is possible across Windows Server 2019, 2022, and 2025 as well as Windows 10 Version 1809 through a use-after-free vulnerability (CWE-416) in the Reliable Multicast Transport Driver (rmcast.sys), a kernel-mode component. An unauthenticated network attacker can exploit a race condition in the driver to corrupt freed kernel memory and achieve arbitrary code execution at SYSTEM privilege level. No public exploit has been identified at time of analysis; the CVSS 8.1 rating reflects high attack complexity (AC:H) due to the timing-sensitive nature of use-after-free race condition exploitation, though a vendor patch is available.
Remote code execution in Windows Active Directory Domain Services allows unauthenticated network attackers to exploit a use-after-free memory corruption flaw and execute arbitrary code on domain controllers. The vulnerability spans virtually the entire Windows Server ecosystem from 2012 through 2025 and extends to Windows 10 and Windows 11 client builds running AD DS components, creating an exceptionally broad attack surface across enterprise environments. Microsoft has released patches; no public exploit or CISA KEV listing has been identified at time of analysis.
Heap-based buffer overflow in the Microsoft JScript scripting engine enables unauthenticated remote code execution across a broad range of Windows client and server platforms. The flaw (CWE-122) resides in the legacy JScript engine bundled with Windows 10, Windows 11, and Windows Server 2012 R2 through 2025, exposing systems to full confidentiality, integrity, and availability compromise without requiring user interaction. No CISA KEV listing or public proof-of-concept has been identified at time of analysis; however, the high attack complexity (AC:H) indicates reliable exploitation demands skilled heap-grooming techniques, moderating the risk of opportunistic mass exploitation.
Authentication bypass in Ivanti Sentry before R10.6.4, R10.7.3, and R10.8.2 allows a remote unauthenticated attacker to gain administrative-level access to the appliance. Rooted in CWE-288 (Authentication Bypass Using an Alternate Path or Channel), the flaw permits circumventing the primary authentication mechanism - likely via an unprotected API endpoint or secondary management interface - without any credentials or user interaction. No public exploit or CISA KEV listing is associated at time of analysis, though the vendor self-disclosed via a security advisory, and the all-high C:H/I:H/A:H impact from administrative compromise makes this a critical patching priority for enterprises running Sentry in mobile security gateway roles.
Remote code execution is possible in fastify-cli 1.5.0 through 8.0.0 when the Node.js Inspector is activated via a debug flag: the CLI ignores the user-supplied bind address and instead binds the Inspector to an overly broad network interface, exposing it beyond the local loopback. Because the Node.js Inspector protocol (Chrome DevTools Protocol) permits unrestricted JavaScript evaluation, any remote party that can reach the exposed Inspector port gains full code execution on the developer's machine with no authentication required. No public exploit code has been identified at time of analysis, and the EPSS signal is not provided, but the Inspector protocol itself is well-understood and trivially exploitable once the port is reachable.

The flaw resides in `p2p_process_prov_disc_bootstrap_req()` within `p2p_pd.c`, where a malformed provision discovery bootstrap request triggers an out-of-bounds write on the heap. Android 16, Android 16-QPR2, and Android 17 are confirmed affected per the September 2026 Android Security Bulletin; no public exploit code exists and EPSS at 0.13% (3rd percentile) reflects minimal current exploitation activity.
Out-of-bounds write in Android's NFC RoutingManager (checkUikcListenConfigNeeded in RoutingManager.cpp) enables remote code execution from adjacent NFC proximity on Android 16-QPR2 and Android 17 without requiring user interaction. The missing bounds check in UICC listen configuration handling allows a proximal attacker to corrupt memory in the NFC daemon, leading to full code execution in that process context. No public exploit has been identified at time of analysis; SSVC rates technical impact as total but exploitation status as none.
