Remote attackers with low-level authentication can achieve full system compromise on Tenda AC5 routers running firmware version 15.03.06.47 by exploiting a stack-based buffer overflow in the addressNat POST request handler. The fromAddressNat function fails to validate the 'page' parameter, enabling memory corruption that leads to high confidentiality, integrity, and availability impact (CVSS 8.8). Publicly available exploit code exists, significantly lowering the barrier to exploitation.

Stack buffer overflow in ImageMagick and Magick.NET due to incorrect pointer arithmetic on certain platforms allows local attackers to write one byte past allocated stack boundaries, causing denial of service. ImageMagick versions prior to 7.1.2-18 and 6.9.13-43, along with multiple Magick.NET NuGet packages, are affected. The vulnerability requires local access and specific platform conditions, but succeeds without user interaction.

The Zen C compiler (versions prior to 0.4.4) crashes or enables arbitrary code execution when processing maliciously crafted .zc source files containing excessively long identifiers for structs, functions, or traits, triggering a stack-based buffer overflow (CWE-121). A proof-of-concept exploit exists per SSVC assessment, though attack complexity remains moderate as it requires local access and user interaction (CVSS:3.1/AV:L/AC:L/PR:N/UI:R). Vendor-released patch: version 0.4.4.

Stack-based buffer overflow in EVerest EV charging software allows unauthenticated local attackers to execute arbitrary code via overly long CAN interface names during initialization. The vulnerability (CWE-121) affects everest-core versions prior to 2026.02.0 with CVSS 8.4 (High severity). Proof-of-concept exploit code exists according to SSVC assessment, and the flaw triggers before privilege checks, enabling attack with no user privileges required. The vulnerability is tracked as EUVD-2026-16199 by ENISA.

Remote code execution vulnerability in EVerest electric vehicle charging software stack allows adjacent network attackers to execute arbitrary code by sending malformed SLAC protocol frames. EVerest-core versions prior to 2026.02.0 are affected due to a stack buffer overflow in HomeplugMessage::setup_payload that trusts an attacker-controlled length parameter in release builds. SSVC analysis indicates proof-of-concept exploit code exists, though the vulnerability is not automatable and requires adjacent network access (CVSS 8.8, AV:A).

Remote attackers can exploit a stack-based buffer overflow in the /cgi-bin/nas.cgi endpoint of Wavlink WL-NU516U1 by manipulating the Content-Length parameter to achieve unauthenticated remote code execution. Public exploit code is available for this vulnerability, and no patch has been released despite vendor notification. Authentication is required to trigger the flaw, limiting exposure to authenticated users or those with network access to the device.

Remote code execution in Stack Overflow's RPCSEC_GSS implementation results from a stack buffer overflow in packet signature validation that fails to properly bounds-check copied data. An unauthenticated remote attacker can exploit this vulnerability by sending specially crafted packets to trigger kernel-level code execution on systems with kgssapi.ko loaded, or userspace code execution in applications running an RPC server with librpcgss_sec. No patch is currently available for this high-severity vulnerability.

A stack-based buffer overflow vulnerability in the P2P API service in BS Producten Petcam with firmware 33.1.0.0818 allows unauthenticated attackers within network range to overwrite the instruction.

Mod_gnutls, a TLS module for Apache HTTPD, contains a stack-based buffer overflow vulnerability in its client certificate verification code. Versions prior to 0.12.3 and 0.13.0 fail to validate the length of client-provided certificate chains before writing pointers to a fixed-size array, typically causing segmentation faults (denial of service) and theoretically enabling stack corruption. Only configurations explicitly requiring client certificate verification are affected; default configurations using 'GnuTLSClientVerify ignore' are not vulnerable.
