Common Weakness Enumeration

CWE-416

Allowed

Use After Free

Abstraction: Variant · Status: Stable

API response cwe.mitre.org

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

10838 vulnerabilities reference this CWE, most recent first.

Title
Running certain aggregation operations with the SBE engine may lead to unexpected behavior on MongoDB Server
Summary
An authenticated user may trigger a use after free that may result in MongoDB Server crash and other unexpected behavior, even if the user does not have authorization to shut down a server. The crash is triggered on affected versions by issuing an aggregation framework operation using a specific combination of rarely-used aggregation pipeline expressions. This issue affects MongoDB Server v6.0 version prior to 6.0.21, MongoDB Server v7.0 version prior to 7.0.17 and MongoDB Server v8.0 version prior to 8.0.4 when the SBE engine is enabled.

Title
PDF-XChange Editor App Object Use-After-Free Remote Code Execution Vulnerability
Summary
PDF-XChange Editor App Object Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of PDF-XChange Editor. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of App objects. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26823.

Title
PDF-XChange Editor U3D File Parsing Use-After-Free Information Disclosure Vulnerability
Summary
PDF-XChange Editor U3D File Parsing Use-After-Free Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of PDF-XChange Editor. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of U3D files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-26643.

CVE-2025-6275 (GCVE-0-2025-6275)

Vulnerability from cvelistv5 – Published: 2025-06-19 19:31 – Updated: 2025-06-23 19:30
VLAI
Title
WebAssembly wabt binary-reader-interp.cc GetFuncOffset use after free
Summary
A vulnerability was found in WebAssembly wabt up to 1.0.37. It has been declared as problematic. Affected by this vulnerability is the function GetFuncOffset of the file src/interp/binary-reader-interp.cc. The manipulation leads to use after free. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used. A similar issue reported during the same timeframe was disputed by the code maintainer because it might not affect "real world wasm programs". Therefore, this entry might get disputed as well in the future.

Strategy: Attack Surface Reduction

When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
