Stack-based buffer overflow in the Wavlink WL-NU516U1 NAS device's nas.cgi password change handler allows remote unauthenticated attackers to potentially execute arbitrary code by supplying an oversized User1Passwd argument to the change_password function. Affecting the MT7628 firmware variant (708c073-mt7628), this carries a CVSS 4.0 score of 8.9 with full confidentiality, integrity, and availability impact and no privileges or user interaction required. A public proof-of-concept has been published and a vendor-released firmware patch is available as of 2026-07-13; no confirmed CISA KEV listing at time of analysis.
Stack-based buffer overflow in the Wavlink WL-NU516U1 (firmware 708c073-mt7628) router's nas.cgi handler lets remote unauthenticated attackers overflow a fixed-size stack buffer by manipulating the HTTP CONTENT_LENGTH value processed via fgets. Successful exploitation can crash the device or execute arbitrary code with full compromise of confidentiality, integrity, and availability. A public write-up (GitHub report2.md) exists, but the flaw is not listed in CISA KEV - no public weaponized exploit is confirmed at time of analysis.
Remote unauthenticated denial of service in 389 Directory Server (389-ds-base, shipped as Red Hat Directory Server 11-13 and within RHEL 6-10) allows an attacker to crash the LDAP daemon by sending a crafted replication extended operation. The flaw is a stack buffer overflow in the RUV parsing path that triggers during payload decoding before any authorization check, so no credentials are needed. No public exploit identified at time of analysis; stack protectors constrain the outcome to a server crash rather than code execution.
Remote code execution via stack-based buffer overflow in Advantech ADAM-3600 EdgeLink's Cookie parsing logic affects all firmware versions prior to 2.8.5.1, exploitable by unauthenticated network attackers when the SafeEnhancement feature is enabled. The vulnerability (CWE-121) allows arbitrary code execution on the edge controller, an OT/IIoT device typically deployed in industrial automation environments. No public exploit has been identified at time of analysis, and EPSS sits at 0.14% (4th percentile), though the industrial attack surface warrants heightened concern due to the operational consequences of device compromise. Notably, the provided CVSS vector (C:H/I:N/A:N) is inconsistent with the described code execution impact - a discrepancy that should be verified with the vendor.
Remote code execution in Advantech ADAM-3600 EdgeLink industrial edge controllers is possible through a stack-based buffer overflow in the device's log message handling functionality, exploitable by unauthenticated network attackers on versions prior to 2.8.5.1. Reported by the Cyber Security Agency of Singapore (CSA), the vulnerability carries a CWE-121 classification - a well-understood root cause class with a history of weaponizable exploits, particularly in embedded and OT/ICS devices. No public exploit has been identified at time of analysis, and EPSS sits at 0.14% (4th percentile), though the network-accessible, unauthenticated nature of the flaw and the industrial deployment context elevate operational risk above what the percentile alone suggests.
Stack-based buffer overflow in Advantech ADAM-3600 EdgeLink's password handling routine enables unauthenticated remote code execution when the SafeEnhancement feature is active. All firmware versions prior to 2.8.5.1 are affected. No public exploit or CISA KEV listing has been identified at time of analysis, but the network-accessible, zero-authentication attack surface on an industrial IoT edge device warrants prompt patching given OT environment exposure.
Stack-based buffer overflow in the Tenda W6-S wireless router (firmware 1.0.0.4(510)) lets remote attackers corrupt stack memory by sending oversized 'GO' and 'index' parameters to the /goform/wifiSSIDset endpoint, where the formwrlSSIDset handler copies them into a fixed 64-byte buffer via unbounded sprintf. Successful exploitation can crash the device or achieve arbitrary code execution with full impact to confidentiality, integrity, and availability. Publicly available exploit code exists in the form of a detailed technical write-up, though there is no public exploit identified as weaponized and no confirmed active exploitation.
Stack-based buffer overflow in IBM Db2's setgid helper binary db2flacc allows a local user with low privileges to overwrite the stack frame and execute arbitrary code with the elevated group permissions of the binary. Both Db2 11.5.x (through 11.5.9) and 12.1.x (through 12.1.4) are affected. No public exploit has been identified and exploitation status is confirmed as none per SSVC, though IBM has released a patch and the SSVC technical impact is rated total, warranting prompt remediation on shared-access Db2 hosts.
Denial of service (and potentially remote code execution) affects the File Explorer component of ASUSTOR's ADM operating system across ADM 4.1.0-4.3.3.RUN1 and 5.0.0-5.1.3.RI81, where a stack-based buffer overflow (CWE-121) lets an authenticated network attacker crash the underlying CGI process by supplying oversized decoded input. Only DoS is vendor-confirmed; the advisory notes further impact may be possible depending on runtime protections, and the vendor-assigned CVSS 4.0 of 8.7 assumes full confidentiality/integrity/availability compromise. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Remote code execution and denial-of-service in the TP-Link TL-WR940N v6 router stem from a stack-based buffer overflow in the kernel-resident RTSP connection-tracking (ALG) module. An attacker who lures a LAN-side client into connecting to an attacker-controlled RTSP server can send a crafted RTSP message that the router's kernel helper mishandles, potentially yielding full device compromise. The flaw is exploitable by an unauthenticated attacker against the router's default configuration; no public exploit has been identified at time of analysis, and the issue is not listed in CISA KEV.
Remote code execution in Xlight FTP Server versions before 3.9.5 allows unauthenticated attackers to corrupt stack memory by sending malformed SSH packets once an AES-GCM cipher is negotiated during the SSH/SFTP handshake. An unvalidated length field is passed directly to the GCM decrypt routine, overwriting the stack cookie and saved return address before any authentication occurs, potentially yielding code execution as the FTP service. Reported by VulnCheck; no public exploit has been identified at time of analysis, but the pre-auth, network-reachable nature makes it a high priority.
Denial of service in Apache Traffic Server (8.0.0-8.1.9, 9.0.0-9.2.14, 10.0.0-10.1.3) lets remote attackers crash the proxy by sending crafted input to the uri_signing or url_sig plugins, which recurse or copy unbounded data onto the stack until it is exhausted (CWE-121 stack-based buffer overflow). Only deployments that have loaded and enabled one of these URL-signing plugins are exposed; the impact is availability-only, with no confidentiality or integrity loss. There is no public exploit identified at time of analysis and the flaw is not in CISA KEV, but the vendor CVSS 4.0 score of 8.2 reflects easy unauthenticated network reach against affected edge nodes.
Denial of service in Apache Traffic Server (versions 8.0.0-8.1.9, 9.0.0-9.2.14, and 10.0.0-10.1.3) arises from a stack-based buffer overflow in the txn_box plugin, which copies attacker-controlled input onto the stack without adequate bounds checking. Remote attackers reaching an ATS instance that loads the txn_box transaction-manipulation plugin can crash the server process; the CVSS 4.0 vector (8.2) scores the impact as availability-only (VA:H) with no confidentiality or integrity loss. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Stack-based buffer overflow and integer overflow in Apache Traffic Server's regex_remap plugin expose production proxy deployments to high-impact compromise via crafted substitution input. Versions 8.0.0 through 8.1.9, 9.0.0 through 9.2.14, and 10.0.0 through 10.1.3 are all affected, with confidentiality, integrity, and availability fully at risk. No public exploit identified at time of analysis, though the network-exploitable nature and full-triad impact make patching urgent for any deployment relying on regex_remap for URL rewriting.
Denial-of-service (and potential memory-corruption) in Apache Traffic Server arises from mishandling of PROXY protocol input, where malformed port fields are truncated and cause a stack buffer overflow (CWE-121). Affected releases span the 8.x, 9.x, and 10.x branches (8.0.0-8.1.9, 9.0.0-9.2.14, 10.0.0-10.1.3), and remote attackers can crash the proxy when it is configured to accept PROXY protocol connections. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; the vendor scores the impact as availability-only (CVSS 4.0 base 8.2).
Denial-of-service (and potential memory corruption) in Apache Traffic Server affects versions 8.0.0-8.1.9, 9.0.0-9.2.14, and 10.0.0-10.1.3 when redirect following is enabled. The proxy copies the client-supplied Host header into a fixed-size stack buffer without bounds checking during redirect handling, so an over-long Host header overflows the stack and crashes the process. There is no public exploit identified at time of analysis, and the vendor-assessed impact is limited to availability (CVSS 4.0 base 8.2).
Denial-of-service
Remote denial of service in ESP32-audioI2S 3.4.5 allows unauthenticated network attackers to crash ESP32 devices by sending crafted MP3 audio data that triggers a buffer overflow in the UnpackFrameHeader() function. Public proof-of-concept code is available, enabling automated exploitation. The vulnerability does not impact confidentiality or integrity.
Remote code execution and credential exfiltration in Snowflake libsnowflakeclient versions before 2.9.2 stem from three distinct flaws in the C client library: a stack-based buffer overflow (CWE-121) and an out-of-bounds write in the file-download path, plus improper validation of connection parameters. A lower-privileged principal sharing an internal stage can plant a file with crafted encryption metadata that corrupts memory in a higher-privileged victim process, while the connection-parameter flaw can redirect outbound authentication requests carrying credentials and tokens to an attacker endpoint. There is no public exploit identified at time of analysis and the CVE is not in CISA KEV; the vendor fixed all issues in 2.9.2, which users must manually install.
Denial of service in MZ Automation's libiec61850 library allows remote unauthenticated attackers to corrupt memory by sending a crafted Read Request, triggering a stack-based buffer overflow (CWE-121). The flaw affects the IEC 61850 MMS server implementation used in power-grid and industrial automation devices, and was disclosed via a CISA ICS advisory (ICSA-26-204-06). No public exploit is identified at time of analysis, and the vendor CVSS 4.0 vector scores only availability impact, indicating a service crash rather than confirmed code execution.
Stack buffer overflow in FFmpeg's Vulkan HEVC hardware decoder (versions 8.0 through 8.1.2) lets remote attackers overwrite return addresses and adjacent stack frames by supplying a crafted HEVC/H.265 bitstream, potentially achieving arbitrary code execution. The flaw sits in the vk_hevc_end_frame function, where a malicious vps_num_hrd_parameters value exceeding HEVC_MAX_SUB_LAYERS overflows stack-allocated arrays. Reported by VulnCheck with an upstream fix committed; there is no public exploit identified at time of analysis and no CISA KEV listing, so exploitation appears theoretical for now despite the high CVSS 4.0 score of 8.7.
Denial-of-service via stack-based buffer overflow affects Hikvision DS-2CD and DS-2DE series IP cameras, where an authenticated attacker sending specially crafted network packets can corrupt memory and force device malfunction. The vendor's CVSS vector claims full confidentiality and integrity impact (C:H/I:H) in addition to availability, hinting at possible code execution beyond the DoS described, though the advisory text only states device malfunction. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
We need to generate a JSON with specific fields. Let's analyze the input. CVE-2026-16418: Stack buffer overflow in V8 in Google Chrome prior to 150.0.7871.182. Allows remote attacker to execute arbitrary code inside a sandbox via crafted HTML page. Chromium security severity: High. CVSS: 8.8, vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H CWE-121: Stack-based Buffer Overflow EPSS: 0.22% (13th percentile) - low. Patch: Available from vendor. SSVC: Exploitation: none, Automatable: no, Technical Impact: total. Tags: RCE, Google, Buffer Overflow, Stack Overflow CPE: cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* (likely all versions before 150.0.7871.182) Affected versions (EUVD): ["Chrome 150.0.7871.182 <150.0.7871.182"] — this is odd, maybe they mean versions prior to 150.0.7871.182. It says "Chrome 150.0.7871.182 <150.0.7871.182" which is likely a formatting issue, should mean versions < 150.0.7871.182. References include Chrome releases blog and Chromium issue. Multi-source intelligence: no mention of KEV, so no active exploitation confirmed. POC? Not mentioned. So no public exploit identified. Now, product_name: "Google Chrome" is specific enough. One to three words. "Google Chrome" is fine. Summary: Need an original synthesis. Not copy description. Start with impact verb and product. So "Remote code execution inside sandbox in Google Chrome prior to 150.0.7871.182 allows a remote attacker to execute arbitrary code via a crafted HTML page due to a stack buffer overflow in V8." Mention not actively exploited, no POC, EPSS low. Keep 2-3 sentences. So: "Remote code execution inside the Chrome sandbox via a crafted HTML page is possible due to a stack buffer overflow in the V8 JavaScript engine. Google Chrome versions before 150.0.7871.182 are affected. No public exploit or active exploitation is known at this time, and the EPSS exploitation probability is low (0.22%)." Technical_context: Explain V8, stack buffer overflow (CWE-121). CPE indicates all Chrome versi
Stack buffer overflow in the Perl module Data::RingBuffer::Shared before 0.04 lets a local peer with write access to the shared memory backing file corrupt adjacent stack frames. The attach-time header validator (ring_validate_header) checks capacity-overflow and total_size consistency but never bounds elem_size, so ring_read_seq memcpys a file-controlled length into a fixed 8-byte destination scalar. No public exploit identified at time of analysis; EPSS is low (0.19%, 9th percentile) and it is not on CISA KEV, but the memory-corruption primitive is unambiguous and a vendor patch (0.04) exists.
Stack-based buffer overflow in libssh's SFTP server allows a connected client to crash the server or potentially execute code by placing files with overlong names into a directory the server subsequently lists. The flaw lives in how libssh builds the SFTP 'longname' field, concatenating attacker-influenced filenames into a fixed-size stack buffer without adequate bounds checking. There is no public exploit identified at time of analysis and EPSS is very low (0.10%), but the memory-corruption nature (CWE-121) and libssh's broad deployment make it worth prioritized patching.
Arbitrary code execution in Adobe DNG SDK version 1.7.1 (build 2536) and earlier arises from a stack-based buffer overflow triggered when parsing a maliciously crafted image file, allowing an attacker to run code in the context of the current user. Applications that embed the DNG SDK to decode Digital Negative (DNG) raw camera files are affected, and successful exploitation requires the victim to open the malicious file. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.
Stack-based buffer overflow in the Tenda AC10 router (firmware 16.03.10.09_multi_TDE01) allows a remote, authenticated attacker to corrupt memory in the httpd/netctrl web service by supplying oversized GetValue/SetValue arguments to the fromAdvSetLanip handler at /goform/AdvSetLanip, potentially achieving code execution or a device crash. Publicly available exploit code exists (published via VulDB and a GitHub advisory), but there is no public exploit identified as actively exploited in the wild. The CVSS 4.0 base score of 7.4 reflects high confidentiality, integrity, and availability impact combined with a low-privilege requirement.
Stack-based buffer overflow in Shibby Tomato router firmware (version 1.28, RT-N5x MIPSR2 Build 124) lets an authenticated remote attacker corrupt the stack through the sub_40BB50 function that renders /proc/webmon_recent_domains, potentially achieving arbitrary code execution on the MIPS-based router. The flaw is remotely reachable and, per the CVSS 4.0 vector, requires low privileges (PR:L) but no user interaction, yielding high confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and no KEV listing; this Tomato fork has been superseded by FreshTomato, so no upstream patch is expected.
Memory-disclosure via heap buffer overflow in libjxl (the JPEG XL reference codec) versions 0.11.2 and earlier lets an attacker who supplies a crafted APNG image trigger an out-of-bounds access in the DecodeImageAPNG function, leaking sensitive process memory. The upstream fix (PR #4804) adds a missing row-index bounds check before accessing frame rows. No public exploit identified at time of analysis; EPSS is low (0.15%, 5th percentile) and the issue is not listed in CISA KEV.
Denial of service in HCL DFXAnalytics version 3.0 and below allows remote unauthenticated attackers to crash or hang the application by supplying oversized input that overflows a fixed-size memory buffer. The flaw stems from missing input-length validation and carries an availability-only impact (CVSS 7.5, AV:N/PR:N); there is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.24%), though CISA SSVC rates the weakness as automatable with partial technical impact.
Denial of service in libsolv's PGP signature verification (solv_pgpvrfy) allows remote attackers to crash automated package and repository processing by supplying a crafted Ed25519 signature. The flaw is a stack-based buffer overflow (CWE-121) triggered when the EdDSA 's' MPI is copied into a fixed 64-byte stack buffer using an attacker-controlled mismatched length. It affects the libsolv dependency solver embedded in Red Hat Enterprise Linux 7/8/9/10, OpenShift, Satellite, RHUI, openSUSE/SUSE, Ubuntu and Debian; no public exploit identified at time of analysis and it is not in CISA KEV.
Stack-based buffer overflow in TDengine (open-source IoT time-series database) versions 3.4.1.6 and earlier allows an authenticated user to trigger a one-byte out-of-bounds write by submitting SQL containing crafted escape sequences (\%, \_, or \x), leading to denial of service and potentially remote code execution. The flaw sits in the SQL parser's trimString() routine, which validates only a single byte of remaining space in the tmpTokenBuf stack buffer before writing escape-processed data. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV; it is fixed in version 3.4.1.14.
Arbitrary code execution in OpenHTJ2K (an open-source High Throughput JPEG 2000 codec by osamu620) versions 0.18.4 and earlier stems from an unchecked coding-pass counter overflowing the fixed pass_length[128] array while parsing crafted JPEG 2000 packet headers. An attacker who supplies a malicious J2K/HTJ2K image to an application built on the library can corrupt adjacent memory and potentially execute code. No public exploit identified at time of analysis; EPSS is low (0.20%) and CISA SSVC rates current exploitation as none, though technical impact is total and the flaw is automatable.
Arbitrary code execution in Adobe Media Encoder arises from a stack-based buffer overflow (CWE-121) triggered when a victim opens a maliciously crafted media file, allowing an attacker to run code in the context of the current user. The CVSS 3.1 base score is 7.8 (local vector, user interaction required, no privileges needed). There is no public exploit identified at time of analysis and it is not listed in CISA KEV, so risk is file-delivery-driven rather than remotely wormable.
Denial of service in NVIDIA Triton Inference Server for Linux stems from a stack-based buffer overflow (CWE-121) reachable by remote, unauthenticated attackers over the network. Per the CVSS 3.1 vector, exploitation requires no privileges or user interaction and impacts only availability (A:H), with no confidentiality or integrity effect. There is no public exploit identified at time of analysis, and the CVE is not listed in CISA KEV; no EPSS score was provided in the input.
Denial of service in Microsoft .NET (versions 8.0, 9.0, and 10.0) and .NET Framework (3.5 through 4.8.1) allows a remote, unauthenticated attacker to crash affected applications by triggering a stack-based buffer overflow (CWE-121) over the network. The flaw impacts availability only - there is no confidentiality or integrity loss and no code execution per the CVSS vector (A:H, C:N, I:N). Microsoft has published an advisory with fixes; there is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV.
Local information disclosure, data tampering, and denial of service in the BlackBerry QNX Neutrino kernel stems from a stack buffer overflow in the entry handler of the TraceEvent() system call, affecting QNX Software Development Platform, QNX OS for Safety, and QNX OS for Medical. An attacker able to run code on the target can craft malicious TraceEvent() arguments to corrupt kernel stack memory, leaking sensitive kernel data, altering kernel state, or crashing the RTOS. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV; exploitation is rated high-complexity (AC:H) despite requiring no prior privileges.
Local privilege escalation in the Windows File History Service lets an authenticated, low-privileged attacker corrupt a stack buffer (CWE-121) to run code with elevated (SYSTEM-level) privileges on affected Windows client and server releases.

There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV, but a vendor patch is available via MSRC.
Local code execution in Microsoft Office Word (Microsoft 365 Apps, Office 2019/LTSC 2021/2024, Word 2016, and the macOS builds) arises from a stack-based buffer overflow triggered when a victim opens a maliciously crafted document. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R) shows an unauthenticated attacker needs no privileges but does require user interaction, and successful exploitation yields full confidentiality, integrity, and availability impact in the user's security context. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but Microsoft has released a patch.
Arbitrary code execution in Microsoft Office Word (and the broader Office/365/SharePoint family) arises from a stack-based buffer overflow (CWE-121) that an attacker triggers when a victim opens a maliciously crafted document. The CVSS 3.1 vector (AV:L/UI:R) confirms this is a file-borne, local-context flaw requiring the user to open attacker-supplied content, yielding full confidentiality, integrity, and availability impact in the user's session. No public exploit identified at time of analysis, and it is not listed in CISA KEV; Microsoft has released a patch via MSRC.
Local code execution in Microsoft Office Word (via a stack-based buffer overflow, CWE-121) lets an attacker run arbitrary code in the context of the user who opens a maliciously crafted document. The flaw affects Microsoft 365 Apps for Enterprise, Office 2019, Office LTSC 2021/2024 (including Mac editions), and the Word component shared with SharePoint Server 2016/2019/Subscription Edition. No public exploit identified at time of analysis, and it is not listed in CISA KEV; exploitation requires the victim to open the attacker's file (UI:R).
Local code execution in Microsoft Excel (and the broader Office 2016/2019/LTSC 2021/2024, Microsoft 365 Apps, Office for Mac, and Office Online Server family) results from a stack-based buffer overflow triggered when a victim opens a maliciously crafted spreadsheet. An attacker who convinces a user to open a booby-trapped file can run arbitrary code in the context of that user, with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and it is not on CISA KEV, but the ubiquity of Excel and Microsoft's own advisory make this a routine patch-Tuesday-class priority.
Local code execution in Microsoft's Resilient File System (ReFS) driver affects Windows 11 (24H2, 25H2, 26H1) and Windows Server 2025, where a stack-based buffer overflow (CWE-121) can be triggered when a victim interacts with attacker-crafted ReFS data. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R) shows an unauthenticated but user-interaction-dependent local attack yielding full confidentiality, integrity, and availability impact. No public exploit identified at time of analysis and the flaw is not on CISA KEV, so it currently represents a patch-priority rather than an active-exploitation emergency.
Denial of service in Microsoft Active Directory Federation Services (AD FS) allows a remote, unauthenticated attacker to crash the service by sending crafted network input that overflows a stack buffer (CWE-121). Because AD FS commonly fronts single sign-on for Microsoft 365, Azure AD, and federated web applications, an outage cascades into loss of authentication for every relying-party application. There is no public exploit identified at time of analysis and the flaw is not in CISA KEV; a Microsoft patch is available, and the CVSS 3.1 score is 7.5 (availability-only impact).
Local privilege elevation in the Windows Graphics Device Interface (GDI) component allows an already-authenticated, low-privileged user to run code at a higher privilege level by triggering a stack-based buffer overflow (CWE-121).

No public exploit has been identified and exploitation status is confirmed as none per SSVC, though IBM has released a patch and the SSVC technical impact is rated total, warranting prompt remediation on shared-access Db2 hosts.
Denial of service (and potentially remote code execution) affects the File Explorer component of ASUSTOR's ADM operating system across ADM 4.1.0-4.3.3.RUN1 and 5.0.0-5.1.3.RI81, where a stack-based buffer overflow (CWE-121) lets an authenticated network attacker crash the underlying CGI process by supplying oversized decoded input. Only DoS is vendor-confirmed; the advisory notes further impact may be possible depending on runtime protections, and the vendor-assigned CVSS 4.0 of 8.7 assumes full confidentiality/integrity/availability compromise. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Remote code execution and denial-of-service in the TP-Link TL-WR940N v6 router stem from a stack-based buffer overflow in the kernel-resident RTSP connection-tracking (ALG) module. An attacker who lures a LAN-side client into connecting to an attacker-controlled RTSP server can send a crafted RTSP message that the router's kernel helper mishandles, potentially yielding full device compromise. The flaw is exploitable by an unauthenticated attacker against the router's default configuration; no public exploit has been identified at time of analysis, and the issue is not listed in CISA KEV.
Remote code execution in Xlight FTP Server versions before 3.9.5 allows unauthenticated attackers to corrupt stack memory by sending malformed SSH packets once an AES-GCM cipher is negotiated during the SSH/SFTP handshake. An unvalidated length field is passed directly to the GCM decrypt routine, overwriting the stack cookie and saved return address before any authentication occurs, potentially yielding code execution as the FTP service. Reported by VulnCheck; no public exploit has been identified at time of analysis, but the pre-auth, network-reachable nature makes it a high priority.
Denial of service in Apache Traffic Server (8.0.0-8.1.9, 9.0.0-9.2.14, 10.0.0-10.1.3) lets remote attackers crash the proxy by sending crafted input to the uri_signing or url_sig plugins, which recurse or copy unbounded data onto the stack until it is exhausted (CWE-121 stack-based buffer overflow). Only deployments that have loaded and enabled one of these URL-signing plugins are exposed; the impact is availability-only, with no confidentiality or integrity loss. There is no public exploit identified at time of analysis and the flaw is not in CISA KEV, but the vendor CVSS 4.0 score of 8.2 reflects easy unauthenticated network reach against affected edge nodes.
Denial of service in Apache Traffic Server (versions 8.0.0-8.1.9, 9.0.0-9.2.14, and 10.0.0-10.1.3) arises from a stack-based buffer overflow in the txn_box plugin, which copies attacker-controlled input onto the stack without adequate bounds checking. Remote attackers reaching an ATS instance that loads the txn_box transaction-manipulation plugin can crash the server process; the CVSS 4.0 vector (8.2) scores the impact as availability-only (VA:H) with no confidentiality or integrity loss. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Stack-based buffer overflow and integer overflow in Apache Traffic Server's regex_remap plugin expose production proxy deployments to high-impact compromise via crafted substitution input.

No public exploit identified at time of analysis, though the network-exploitable nature and full-triad impact make patching urgent for any deployment relying on regex_remap for URL rewriting.
Denial-of-service (and potential memory-corruption) in Apache Traffic Server arises from mishandling of PROXY protocol input, where malformed port fields are truncated and cause a stack buffer overflow (CWE-121). Affected releases span the 8.x, 9.x, and 10.x branches (8.0.0-8.1.9, 9.0.0-9.2.14, 10.0.0-10.1.3), and remote attackers can crash the proxy when it is configured to accept PROXY protocol connections. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; the vendor scores the impact as availability-only (CVSS 4.0 base 8.2).
Denial-of-service (and potential memory corruption) in Apache Traffic Server affects versions 8.0.0-8.1.9, 9.0.0-9.2.14, and 10.0.0-10.1.3 when redirect following is enabled. The proxy copies the client-supplied Host header into a fixed-size stack buffer without bounds checking during redirect handling, so an over-long Host header overflows the stack and crashes the process. There is no public exploit identified at time of analysis, and the vendor-assessed impact is limited to availability (CVSS 4.0 base 8.2).
Denial-of-service
Remote denial of service in ESP32-audioI2S 3.4.5 allows unauthenticated network attackers to crash ESP32 devices by sending crafted MP3 audio data that triggers a buffer overflow in the UnpackFrameHeader() function. Public proof-of-concept code is available, enabling automated exploitation. The vulnerability does not impact confidentiality or integrity.
Remote code execution and credential exfiltration in Snowflake libsnowflakeclient versions before 2.9.2 stem from three distinct flaws in the C client library: a stack-based buffer overflow (CWE-121) and an out-of-bounds write in the file-download path, plus improper validation of connection parameters. A lower-privileged principal sharing an internal stage can plant a file with crafted encryption metadata that corrupts memory in a higher-privileged victim process, while the connection-parameter flaw can redirect outbound authentication requests carrying credentials and tokens to an attacker endpoint. There is no public exploit identified at time of analysis and the CVE is not in CISA KEV; the vendor fixed all issues in 2.9.2, which users must manually install.
Denial of service in MZ Automation's libiec61850 library allows remote unauthenticated attackers to corrupt memory by sending a crafted Read Request, triggering a stack-based buffer overflow (CWE-121). The flaw affects the IEC 61850 MMS server implementation used in power-grid and industrial automation devices, and was disclosed via a CISA ICS advisory (ICSA-26-204-06). No public exploit is identified at time of analysis, and the vendor CVSS 4.0 vector scores only availability impact, indicating a service crash rather than confirmed code execution.
Stack buffer overflow in FFmpeg's Vulkan HEVC hardware decoder (versions 8.0 through 8.1.2) lets remote attackers overwrite return addresses and adjacent stack frames by supplying a crafted HEVC/H.265 bitstream, potentially achieving arbitrary code execution. The flaw sits in the vk_hevc_end_frame function, where a malicious vps_num_hrd_parameters value exceeding HEVC_MAX_SUB_LAYERS overflows stack-allocated arrays. Reported by VulnCheck with an upstream fix committed; there is no public exploit identified at time of analysis and no CISA KEV listing, so exploitation appears theoretical for now despite the high CVSS 4.0 score of 8.7.
Denial-of-service via stack-based buffer overflow affects Hikvision DS-2CD and DS-2DE series IP cameras, where an authenticated attacker sending specially crafted network packets can corrupt memory and force device malfunction. The vendor's CVSS vector claims full confidentiality and integrity impact (C:H/I:H) in addition to availability, hinting at possible code execution beyond the DoS described, though the advisory text only states device malfunction. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.

SSVC: Exploitation: none, Automatable: no, Technical Impact: total. Tags: RCE, Google, Buffer Overflow, Stack Overflow CPE: cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* (likely all versions before 150.0.7871.182) Affected versions (EUVD): ["Chrome 150.0.7871.182 <150.0.7871.182"] — this is odd, maybe they mean versions prior to 150.0.7871.182. It says "Chrome 150.0.7871.182 <150.0.7871.182" which is likely a formatting issue, should mean versions < 150.0.7871.182. References include Chrome releases blog and Chromium issue. Multi-source intelligence: no mention of KEV, so no active exploitation confirmed. POC? Not mentioned. So no public exploit identified. Now, product_name: "Google Chrome" is specific enough. One to three words. "Google Chrome" is fine. Summary: Need an original synthesis. Not copy description. Start with impact verb and product. So "Remote code execution inside sandbox in Google Chrome prior to 150.0.7871.182 allows a remote attacker to execute arbitrary code via a crafted HTML page due to a stack buffer overflow in V8." Mention not actively exploited, no POC, EPSS low. Keep 2-3 sentences. So: "Remote code execution inside the Chrome sandbox via a crafted HTML page is possible due to a stack buffer overflow in the V8 JavaScript engine. Google Chrome versions before 150.0.7871.182 are affected. No public exploit or active exploitation is known at this time, and the EPSS exploitation probability is low (0.22%)." Technical_context: Explain V8, stack buffer overflow (CWE-121). CPE indicates all Chrome versi
Stack buffer overflow in the Perl module Data::RingBuffer::Shared before 0.04 lets a local peer with write access to the shared memory backing file corrupt adjacent stack frames. The attach-time header validator (ring_validate_header) checks capacity-overflow and total_size consistency but never bounds elem_size, so ring_read_seq memcpys a file-controlled length into a fixed 8-byte destination scalar. No public exploit identified at time of analysis; EPSS is low (0.19%, 9th percentile) and it is not on CISA KEV, but the memory-corruption primitive is unambiguous and a vendor patch (0.04) exists.
Stack-based buffer overflow in libssh's SFTP server allows a connected client to crash the server or potentially execute code by placing files with overlong names into a directory the server subsequently lists. The flaw lives in how libssh builds the SFTP 'longname' field, concatenating attacker-influenced filenames into a fixed-size stack buffer without adequate bounds checking. There is no public exploit identified at time of analysis and EPSS is very low (0.10%), but the memory-corruption nature (CWE-121) and libssh's broad deployment make it worth prioritized patching.
Arbitrary code execution in Adobe DNG SDK version 1.7.1 (build 2536) and earlier arises from a stack-based buffer overflow triggered when parsing a maliciously crafted image file, allowing an attacker to run code in the context of the current user. Applications that embed the DNG SDK to decode Digital Negative (DNG) raw camera files are affected, and successful exploitation requires the victim to open the malicious file. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.
Stack-based buffer overflow in the Tenda AC10 router (firmware 16.03.10.09_multi_TDE01) allows a remote, authenticated attacker to corrupt memory in the httpd/netctrl web service by supplying oversized GetValue/SetValue arguments to the fromAdvSetLanip handler at /goform/AdvSetLanip, potentially achieving code execution or a device crash. Publicly available exploit code exists (published via VulDB and a GitHub advisory), but there is no public exploit identified as actively exploited in the wild.

Publicly available exploit code exists (VulDB), though it is not listed in CISA KEV, so there is no public exploit identified as actively exploited at time of analysis. The device has been end-of-life since 2011 and the vendor declined to confirm the flaw, meaning no fix will be issued.
Denial of service in Espressif's ESP-IDF JPEG driver (versions 6.0.1, 5.5.4, 5.4.4, 5.3.5 and likely earlier) stems from an out-of-bounds stack write in jpeg_parse_dqt_marker(), where the attacker-controlled DQT marker Tq nibble indexes the qt_tbl array without a 0..3 bounds check. Any application that feeds untrusted JPEG data into the hardware JPEG decode path can be reliably crashed by a single malformed image. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV; the vendor has released a fix in 6.0.2 with backports pending for the 5.x branches.
Denial of service in the Tenda CP3 V3.0 IP camera (firmware V31.1.9.91) lets an unauthenticated remote attacker crash the RTSP service by sending a crafted second SETUP request after a valid RTSP handshake, knocking the camera offline for every client on the network. The flaw is a stack-based buffer overflow (CWE-121) in the RTSP second-stage URL routing parser; publicly available exploit code exists via a GitHub write-up, though no active exploitation is confirmed and the CVSS availability-only impact means it is a crash, not code execution, at time of analysis.
Denial of service in the RTSP service of Tenda CP3 V3.0 IP cameras (firmware V31.1.9.91) allows an unauthenticated remote attacker on the local network to crash the streaming service with a single crafted SETUP request. Because the second-stage URL routing parser does not validate the URL field length, a request whose URL is exactly four repetitions of a valid RTSP URL overflows a stack buffer and terminates the RTSP process, cutting off all clients. Publicly available exploit code exists (researcher write-up on GitHub); this is not listed in CISA KEV and no active exploitation is confirmed.
Denial of service in the Tenda CP3 V3.0 IP camera (firmware V31.1.9.91) lets an unauthenticated remote attacker crash the onboard RTSP service by sending a PLAY request whose Range header carries an over-long clock= value, triggering a stack-based buffer overflow (CWE-121). The flaw affects only availability - a successful attack knocks the camera's video streaming offline until it recovers or is restarted, with no confirmed path to code execution or data disclosure. There is a public research write-up on GitHub, but no active exploitation is recorded in CISA KEV and EPSS rates exploitation likelihood as low (0.19%, 9th percentile).
Denial of service in GStreamer's DTLS plugin allows a remote unauthenticated attacker to crash any application that performs a DTLS handshake (notably WebRTC/webrtcbin pipelines) by presenting a TLS certificate with an oversized Subject Distinguished Name.

This CVE-2026-11771 flaw was fixed in the coordinated OpenVPN 2.7.5 / 2.6.21 release of 1 July 2026 alongside several other memory-safety bugs; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Impact is limited to availability (VA:H) with no confidentiality or integrity effect, and exploitation only applies to clients configured to route through an NTLMv2-authenticated HTTP proxy.
Denial of service in the UTT nv518G gateway/router (firmware nv518GV3v3.2.7-210919-161313) lets a remote attacker crash the device by sending crafted input to the gohead/sub_448384 (FUN_00448384) handler, triggering a stack-based buffer overflow. The CVSS 3.1 vector marks it network-reachable and unauthenticated with high availability impact but no confidentiality or integrity effect. Publicly available exploit code exists via a GitHub CVE report; there is no CISA KEV listing and no EPSS score in the provided data.
Stack-based buffer overflow in FatFs R0.16 and earlier allows an attacker who can present crafted exFAT media to corrupt the stack via f_getlabel(), because the exFAT volume-label length field (XDIR_NumLabel) is trusted without enforcing the specification maximum. FatFs is an embedded FAT/exFAT filesystem library used across microcontroller and IoT firmware, so any device that mounts and reads the label of attacker-supplied storage is exposed. Publicly available exploit code exists (runZero advisory and SSVC 'PoC'), but there is no public exploit identified in active use and it is not listed in CISA KEV.
Stack-based buffer overflow in the Wavlink WL-NU516U1-A wireless range extender (firmware M16U1_V240425) lets a remote, low-privileged attacker corrupt memory by sending an oversized Guest_ssid POST parameter to the sub_407504 function in /cgi-bin/wireless.cgi. The flaw was reported by VulDB, publicly available exploit code exists, and it carries a CVSS 4.0 base score of 7.4; there is no evidence of active exploitation in CISA KEV at this time.
Stack-based buffer overflow in the Tenda JD12L router (firmware 16.03.53.23) lets remote attackers corrupt memory via the 'page' parameter handled by the fromNatStaticSetting function at the /goform/NatStaticSetting endpoint. Publicly available exploit code exists, and the CVSS 4.0 vector (PR:L) indicates an authenticated user on the device's web interface can trigger high confidentiality, integrity and availability impact. There is no public exploit identified as actively used in the wild - exploitation is proof-of-concept only at this time.
Stack-based buffer overflow in the Tenda JD12L router (firmware 16.03.53.23) lets a remote attacker corrupt memory by manipulating the 'page' parameter handled by the fromAddressNat function at the /goform/addressNat endpoint, potentially achieving code execution or device crash. Publicly available exploit code exists and the issue was disclosed by VulDB, though there is no public exploit identified as actively exploited in the wild. With a CVSS 4.0 base score of 7.4 and PR:L, exploitation requires some level of authenticated access to the web management interface.
Stack-based buffer overflow in the Tenda JD12L router (firmware 16.03.53.23) allows remote attackers to corrupt memory by manipulating the security_5g argument sent to the formWifiBasicSet handler at /goform/WifiBasicSet, potentially achieving denial of service or arbitrary code execution on the device. The flaw is network-reachable but, per the CVSS 4.0 vector, requires low-level authentication (PR:L), and publicly available exploit code exists. There is no public exploit identified as actively exploited in CISA KEV, and the EPSS score was not provided.
Remote unauthenticated stack-based buffer overflow in the vlsvr login service of GeoVision GV-LPC2011 and GV-LPC2211 license plate capture cameras (firmware V1.12 and earlier) lets a remote attacker corrupt memory by sending an over-length login field, enabling denial of service and potentially arbitrary code execution. The flaw requires no authentication and no user interaction (CVSS 9.8). No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Unauthenticated remote code execution and denial of service in GeoVision GV-LPC2011 and GV-LPC2211 license plate camera devices (firmware V1.12 and earlier) stems from a stack-based buffer overflow in the ssvr streaming component's RTSP Digest authentication parser. A remote attacker reachable on the RTSP service can send overly long authentication field data to corrupt the stack, crashing the device or potentially executing arbitrary code with no credentials or user interaction. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but the CVSS 9.8 rating and unauthenticated network vector make it a high-priority patching target.
Remote code execution and denial of service in GeoVision GV-LPC2011 and GV-LPC2211 license-plate-recognition cameras (V1.12 and earlier) arise from a stack-based buffer overflow in the ssvr component's RTSP custom authentication handling. The CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates an unauthenticated remote attacker can trigger memory corruption with a single crafted RTSP request, yielding crash-level DoS and potential arbitrary code execution. No public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Remote code execution in GeoVision GV-LPC2011 and GV-LPC2211 license-plate-recognition cameras (firmware V1.12 and earlier) stems from a stack-based buffer overflow in the embedded thttpd web server, where overly long parameters in a specific request path overrun a fixed-size stack buffer. An unauthenticated remote attacker (per CVSS PR:N) can send a single crafted HTTP request to corrupt memory and cause denial of service or potentially execute arbitrary code on the device. No public exploit has been identified at time of analysis, but the CVSS 9.8 rating and lack of authentication make this a high-priority embedded-device exposure.
