WINSTAR WN572HP3 v230525 was discovered to contain a heap overflow via the CONTENT_LENGTH variable at /cgi-bin/upload.cgi.

Pillow is a Python imaging library. In versions 11.2.0 to before 11.3.0, there is a heap buffer overflow when writing a sufficiently large (>64k encoded with default settings) image in the DDS format due to writing into a buffer without checking for available space. This only affects users who save untrusted data as a compressed DDS image. This issue has been patched in version 11.3.0.

Electron is an open source framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. In versions prior to 28.3.2, 29.3.3, and 30.0.3, the nativeImage.createFromPath() and nativeImage.createFromBuffer() functions call a function downstream that is vulnerable to a heap buffer overflow. An Electron program that uses either of the affected functions is vulnerable to a buffer overflow if an attacker is in control of the image's height, width, and contents. This issue has been patched in versions 28.3.2, 29.3.3, and 30.0.3. There are no workarounds for this issue.

A heap buffer overflow in the image processing binary of the MIB3 infotainment unit allows an attacker to execute arbitrary code on it.

The list of affected MIB3 OEM part numbers is provided in the referenced resources.

CVE-2025-6660 is a heap-based buffer overflow vulnerability in PDF-XChange Editor's GIF file parsing engine that enables remote code execution with high severity (CVSS 7.8). The vulnerability affects users who open malicious GIF files or visit compromised web pages hosting malicious GIFs, requiring user interaction for exploitation. The flaw stems from inadequate validation of user-supplied data lengths before copying to fixed-length buffers, allowing attackers to overwrite heap memory and execute arbitrary code in the application's context.

CVE-2025-52566 is a signed vs. unsigned integer overflow vulnerability in llama.cpp's tokenizer (llama_vocab::tokenize function) that enables heap buffer overflow during text tokenization. This affects all versions of llama.cpp prior to b5721, and attackers can trigger the vulnerability with specially crafted text input during the inference process, potentially achieving code execution with high confidentiality, integrity, and availability impact. The vulnerability requires local access and user interaction but has a high CVSS score of 8.6; KEV status and active exploitation data are not currently available, but the patch exists in version b5721.

Buffer overflow in OpenVPN ovpn-dco-win version 1.3.0 and earlier and version 2.5.8 and earlier allows a local user process to send a too large control message buffer to the kernel driver resulting in a system crash

Heap-based buffer overflow vulnerability in PRJ file parsing that allows local attackers with user interaction to achieve high-impact memory corruption, potentially leading to arbitrary code execution or information disclosure. The vulnerability stems from insufficient validation of user-supplied data within PRJ file structures, enabling attackers to read and write past allocated buffer boundaries. No current KEV status or active exploitation data is available in public records, but the local attack vector and requirement for user interaction (file opening) suggest moderate real-world risk despite the high CVSS score.

A buffer overflow vulnerability (CVSS 9.8). Critical severity with potential for significant impact on affected systems.

A vulnerability has been identified in the libarchive library. This flaw can lead to a heap buffer over-read due to the size of a filter block potentially exceeding the Lempel-Ziv-Storer-Schieber (LZSS) window. This means the library may attempt to read beyond the allocated memory buffer, which can result in unpredictable program behavior, crashes (denial of service), or the disclosure of sensitive information from adjacent memory regions.

CVE-2024-52035 is an integer overflow vulnerability in catdoc 0.95's OLE Document File Allocation Table (FAT) parser that enables heap-based memory corruption when processing malformed files. The vulnerability affects users of catdoc 0.95 who process untrusted OLE documents (Microsoft Office legacy formats), allowing local attackers to corrupt heap memory and potentially achieve code execution. No active KEV status or widespread exploitation has been reported; however, the high CVSS score (8.4) and local attack vector indicate moderate real-world risk for environments processing user-supplied documents.

1-byte heap buffer overflow in NeKernal OS version 0.0.2's `rt_copy_memory` function, where a null terminator is unconditionally written beyond the destination buffer boundary when the copy length equals the buffer size (256 bytes). This vulnerability affects local attackers with no privilege requirements and can result in high-impact compromise of confidentiality, integrity, and availability. The patch (commit fb7b7f658327f659c6a6da1af151cb389c2ca4ee) removes the overflow-causing null terminator write; no active exploitation or public POC is currently documented, but the CVSS 8.6 score reflects significant severity.
