Affecting every supported Windows desktop and server release from Server 2012 through Windows 11 26H1 and Server 2025, the vulnerability is reached via the Spooler's RPC interface, which historically has been a prolific attack surface (PrintNightmare, SpoolFool). No public exploit code has been identified at time of analysis and it does not appear in CISA KEV, but the breadth of affected versions and ubiquitous deployment make rapid patching critical.

Use-after-free in the Windows Bind Filter Driver enables a locally authenticated, low-privileged attacker to escalate privileges to SYSTEM on affected Windows 11 and Windows Server 2025 builds. The flaw (CWE-416) resides in a kernel-mode filter driver, meaning successful exploitation yields full control over the operating system. No public exploit or active exploitation has been identified at time of analysis, but Microsoft has released patches addressing the affected builds.

Use-after-free memory corruption in Microsoft SQL Server enables a network-authenticated low-privileged attacker to achieve arbitrary code execution with full confidentiality, integrity, and availability impact. Affected versions span all actively serviced SQL Server releases from 2017 through 2025, across both Cumulative Update (CU) and General Distribution Release (GDR) servicing branches. No public exploit or CISA KEV listing has been identified at time of analysis, but the low authentication barrier (any valid SQL Server login) and network accessibility make this a high-priority patching target in enterprise environments.

Remote code execution in Windows Active Directory Domain Services (AD DS) exposes domain controllers across Windows Server 2012 through 2025 to exploitation by low-privileged authenticated domain users via a use-after-free memory corruption flaw. The vulnerability (CWE-416) is reachable over the network but requires high attack complexity, likely a race condition or heap-grooming technique, to achieve fully controlled memory corruption resulting in arbitrary code execution with C:H/I:H/A:H impact. No public exploit has been identified at time of analysis; vendor-released patches are available for all affected Windows versions via the Microsoft Security Response Center.

Local privilege escalation in Windows Push Notifications affects Windows 10, Windows 11, and Windows Server 2022/2025 via a use-after-free (CWE-416) memory corruption flaw, allowing a low-privileged authenticated local user to obtain SYSTEM-level execution. The vulnerability spans nine distinct Windows release branches - including server editions - broadening the enterprise attack surface. No public exploit code or CISA KEV listing has been identified at time of analysis; however, LPE primitives of this class are routinely integrated into post-initial-access attack chains.

Local privilege escalation in Windows Installer via a use-after-free (CWE-416) allows an authenticated user with standard privileges to achieve SYSTEM-level code execution across a broad range of Windows client and server releases. The vulnerability is confirmed by Microsoft MSRC and affects every major supported Windows version from Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 through 2025. No public exploit has been identified at time of analysis, and a vendor-released patch is available through Microsoft's update cycle.

Local privilege escalation via use-after-free (CWE-416) affects a broad swath of Microsoft Windows Server and Windows 10/11 releases, allowing an authenticated low-privilege attacker to gain SYSTEM-level access without user interaction. The CVSS vector (AV:L/AC:L/PR:L/UI:N) confirms exploitation requires only a standard local account and no special configuration, making this a practical post-exploitation stepping stone in any multi-user or RDP-exposed Windows environment. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, but the low attack complexity and Microsoft authorship of the report (secure@microsoft.com) suggest internal discovery and coordinated patch release.

Use-after-free in the Windows VHD miniport driver enables a locally authenticated, low-privileged attacker to escalate privileges to SYSTEM-level access on affected Windows systems. The flaw is present across a broad range of Windows versions - from Windows 10 1809 and Server 2019 through Windows 11 25H2 and Server 2025 - making the attack surface extremely wide. Microsoft has released patches via its standard Patch Tuesday update mechanism; no public exploit code or active exploitation has been identified at time of analysis.

Out-of-bounds memory write in MongoDB Server 8.3.x allows authenticated users with write privileges to crash the mongod server process or potentially achieve arbitrary code execution by supplying crafted storage engine configuration parameters at collection creation time. Versions 8.3.0 through 8.3.8 are affected; a vendor-released fix is available in 8.3.9. No public exploit code or confirmed active exploitation has been identified at time of analysis.

Use-after-free in MongoDB Server 8.3.x (versions 8.3.0 through 8.3.8) allows authenticated users holding read-only privileges to write to freed heap memory by issuing a specific sequence of standard database commands against the query execution memory tracking subsystem. The immediate consequence is a server process crash (denial of service); heap memory corruption may also enable more sophisticated follow-on exploitation. No public exploit or CISA KEV listing has been identified at time of analysis, and a vendor-released patch is available in 8.3.9.

MongoDB Server 8.3.x exposes a type confusion (CWE-843) in its WiredTiger storage engine layer, allowing any authenticated user with readWrite privileges to crash the mongod process and keep it in a crash-loop. By creating a collection with a crafted, incompatible WiredTiger storage configuration option, the attacker causes the storage engine to misinterpret memory layout when subsequent reads are issued against that collection. Because the malicious collection configuration persists across server restarts, the denial-of-service condition is self-sustaining until an operator manually identifies and drops the offending collection. No public exploit or KEV listing has been identified at time of analysis.

Use-after-free memory corruption in Arm's Bifrost, Valhall, and 5th Gen GPU userspace drivers allows a local non-privileged process - including through browser-exposed WebGL or WebGPU operations - to access already-freed memory regions, achieving full confidentiality, integrity, and availability impact. The flaw spans driver revisions from r42p0 through r55p0 across all three GPU families, covering a substantial portion of the Android Mali GPU ecosystem deployed in MediaTek and Samsung Exynos SoCs. No public exploit has been identified at time of analysis, and EPSS sits at 0.14% (4th percentile), but the WebGL/WebGPU trigger path is a notable attack surface reduction that warrants prompt patching on affected devices.

Use-after-free in Arm's Bifrost, Valhall, and 5th Gen GPU Architecture Kernel Drivers enables a local unprivileged process to access deallocated kernel memory through valid GPU memory processing operations, resulting in full confidentiality, integrity, and availability compromise (CVSS C:H/I:H/A:H). The flaw spans broad version ranges across all three driver families from r44p0 through r54p3/r55p0, affecting a large population of devices built on Arm Mali GPU hardware. No active exploitation is confirmed at time of analysis (EPSS 0.14%, no CISA KEV listing), but UAF vulnerabilities in kernel-mode GPU drivers are a well-established and historically weaponized local privilege escalation vector on Android and Linux platforms.

Use-after-free in Arm's Bifrost, Valhall, and 5th Gen GPU Architecture kernel drivers allows a local non-privileged process to access freed GPU memory, yielding full confidentiality, integrity, and availability impact within the kernel driver context. Affected revisions span a wide range across all three driver families - from r49p3 through r55p0 depending on the product line - placing a large population of Android and embedded Arm devices in scope. No public exploit code exists at time of analysis, and EPSS sits at 0.14% (4th percentile), though the low-complexity local attack surface characteristic of GPU driver UAFs has historically attracted sophisticated actors targeting mobile platforms.

Use-after-free in Arm's Valhall and 5th Gen GPU Architecture kernel drivers allows a local non-privileged process to access freed kernel memory by submitting valid GPU processing operations, with potential for full system compromise across confidentiality, integrity, and availability (CVSS C:H/I:H/A:H). Both driver families are affected from r50p0 through r54p3 and at r55p0, covering a wide swath of devices - notably Android smartphones and embedded SoCs - that rely on these GPU drivers. No active exploitation is confirmed (EPSS 0.14%, 4th percentile; no CISA KEV listing) at time of analysis.

Use-after-free in PX4 Autopilot through 1.17.0 allows an adjacent unauthenticated attacker to corrupt flight-stack heap memory by issuing a single `load_mon stop` command over a MAVLink or PXH shell. The bug in `exit_and_cleanup()` frees the LoadMon object and its performance counter before `perf_end()` consumes it, producing a dangling-pointer dereference that corrupts heap objects and destabilizes the autopilot flight stack - in a UAV context, a plausible pathway to loss of vehicle control mid-flight. An upstream fix has been merged as PR #28544; no public exploit code is identified and the CVE is not listed in CISA KEV.

Memory corruption in Siemens Reyrolle 7SR5 digital protection relays (all versions below V2.70) allows a physically-present, unauthenticated attacker to crash the device or potentially execute arbitrary code by sending malformed input over a proprietary communication protocol exposed exclusively during the device's special firmware-update mode. Siemens confirmed the flaw via advisory SSA-142885 and released V2.70 as the fix. No public exploit code or active exploitation has been identified at time of analysis.

Out-of-bounds write in Siemens Reyrolle 7SR5 protection relays (all firmware versions before V2.70) allows unauthenticated remote attackers to crash and reboot the device by sending a crafted HTTP request containing an oversized URL component. The flaw exists in pre-authentication HTTP message processing, meaning no credentials are required; a single malicious request can trigger a forced device reboot and a sustained denial-of-service condition. No public exploit code or CISA KEV listing has been identified at time of analysis, but the OT/substation deployment context significantly amplifies the operational impact of availability loss.

Out-of-bounds write in D-Link DIR-822A firmware A_101 allows network-reachable authenticated attackers to corrupt memory and likely achieve remote code execution by sending a crafted L2TP control message with a malformed Host Name AVP to the vulnerable tunnel_set_params function. A public proof-of-concept demonstrating the specific Host Name AVP overflow has been published on Notion, substantially lowering the exploitation barrier. No vendor-released patch has been identified at time of analysis, leaving affected devices exposed without a direct remediation path.

Buffer overflow in Nordic Semiconductor's nRF Connect SDK Bluetooth CGMS RACP write handler allows an authenticated BLE peer within radio range to overflow a 20-byte static buffer into adjacent BSS memory. Exploitability and exact impact are build-specific: because BSS layout is determined at link time per firmware build, adjacent corrupted data may be security-neutral or may include function pointers or critical control structures enabling code execution or device crash. No public exploit has been identified at time of analysis; the vulnerability was reported through YesWeHack.

Out-of-bounds write in Samsung's open-source Walrus WebAssembly runtime allows a crafted WASM component to corrupt process heap memory via a WASI 0.2 stream-read implementation flaw. The root cause is a `memcpy` in `WASI02Impl.cpp` that copies the requested read length (`size`) rather than the actual bytes read (`read`) from the buffer, writing beyond valid buffer bounds when a partial or short read occurs. A secondary defective bounds check for type-index validation in the WASM component parser compounds the attack surface. A proof-of-concept WASM file (`stream-read-oob-poc.wast`) was committed as part of the fix in PR #482, confirming exploitability; no public exploit independent of the fix has been identified at time of analysis.

Use-after-free in strongSwan's IKEv2 Multi-Key Exchange (Multi-KE, RFC 9370) implementation is triggered when two authenticated IKE peers simultaneously initiate a rekey operation, causing a race condition that corrupts heap memory and can result in remote code execution within the IKE daemon. The attack requires an established IKE session and high-complexity timing to induce the collision, reflected in the CVSS AC:H/PR:L vector. Fixed in strongSwan 6.1.0, released September 7, 2026, alongside six other CVEs disclosed in the same advisory batch. No public exploit identified at time of analysis.

Unauthenticated file read in MikroTik RouterOS WebFig exposes root-owned configuration files - including credential stores - to any network attacker who can reach the management interface. The vulnerability chains an uninitialized principal pointer (CWE-824) in /jsproxy session allocation with an encrypted URI path traversal, allowing pre-authentication escalation of file-read rights followed by namespace escape. Fixed versions 6.49.21 (Long-term), 7.23.4 (Long-term), and 7.24.2 (Stable) are available; a public exploit writeup exists, and CERT-PL's September 2026 reporting references active exploitation of this class of MikroTik vulnerabilities.

Heap buffer overflow in ntop nDPI before version 6.0 allows unauthenticated network-adjacent or remote attackers to corrupt process heap memory by sending crafted packets containing TLS SNI values, HTTP headers, or DNS names with characters that expand during JSON escaping. The root cause in ndpi_json_string_escape (src/lib/ndpi_serializer.c) is that the original bounds check guarded only single-byte writes while escape sequences requiring 2 bytes (e.g., backslash-quote) or 6 bytes (e.g., \u00XX control-character escapes) silently overran the caller-supplied buffer. Vendor-released patch is available via commit 94e82c1 targeting the 6.0 release; no public exploit has been identified at time of analysis.

Out-of-bounds write in Unidata netcdf-c through 4.10.1 allows an attacker who can supply a crafted HDF5 file to corrupt process memory when the application enumerates HDF5 attribute names. The vulnerable function NC4_HDF5_inq_attname() in libhdf5/hdf5attr.c blindly copies HDF5-returned attribute names into a fixed 256-byte destination buffer without validating the source length, a classic CWE-787 stack/heap corruption sink. No public exploit code or CISA KEV listing has been identified at time of analysis, but the deterministic nature of the overflow and the wide use of netcdf-c in scientific pipelines make this a meaningful risk for any application that processes externally-sourced HDF5 data.

Remote denial of service and integrity compromise in IBM i 7.3, 7.4, 7.5, and 7.6 arises from an out-of-bounds write (buffer overflow) reachable by a remote attacker. Per IBM's CVSS 3.1 vector the flaw is network-reachable with no privileges or user interaction, corrupting memory to crash affected services and tamper with data integrity (C:N/I:H/A:H). There is no public exploit identified at time of analysis, EPSS is low (0.32%), and the CISA SSVC framework records exploitation status as none.

Denial-of-service in IBM i 7.3 through 7.6 allows an unauthenticated network-adjacent attacker to crash the ICMPv6 stack by sending a malformed Router Advertisement packet with an invalid prefix length. The underlying flaw is an out-of-bounds write (CWE-787) triggered by absent validation of the RA prefix length field, resulting in limited availability impact without confidentiality or integrity loss. No public exploit code has been identified and this vulnerability is not listed in CISA KEV; a vendor patch is available.

Denial of service in IBM i versions 7.3, 7.4, 7.5, and 7.6 is exploitable remotely by unauthenticated network attackers via a buffer overflow (CWE-787, out-of-bounds write), degrading service availability without requiring credentials or user interaction. IBM has released a patch via their support portal. No public exploit code or active exploitation has been identified at time of analysis, and the CVSS 5.3 score reflects limited practical impact - no confidentiality or integrity compromise.
