Common Weakness Enumeration

CWE-416

Allowed

Use After Free

Abstraction: Variant · Status: Stable

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

10228 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2022-11-09 12:00 – Updated: 2022-11-09 19:02
VLAI
Details

Due to lack of proper memory management, when a victim opens manipulated file received from untrusted sources in SAP 3D Visual Enterprise Author and SAP 3D Visual Enterprise Viewer, Arbitrary Code Execution can be triggered when payload forces:Re-use of dangling pointer which refers to overwritten space in memory. The accessed memory must be filled with code to execute the attack. Therefore, repeated success is unlikely.Stack-based buffer overflow. Since the memory overwritten is random, based on access rights of the memory, repeated success is not assured.

Details

A use after free vulnerability exists in the JavaScript engine of Foxit Software’s Foxit PDF Reader, version 10.1.0.37527. A specially crafted PDF document can trigger reuse of previously free memory which can lead to arbitrary code execution. An attacker needs to trick the user to open the malicious file to trigger this vulnerability. If the browser plugin extension is enabled, visiting a malicious site can also trigger the vulnerability.

GHSA-CQ4F-H5G8-8R5H

Vulnerability from github – Published: 2024-06-20 12:31 – Updated: 2024-08-19 18:32
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

ALSA: hda: Fix UAF of leds class devs at unbinding

The LED class devices that are created by HD-audio codec drivers are registered via devm_led_classdev_register() and associated with the HD-audio codec device. Unfortunately, it turned out that the devres release doesn't work for this case; namely, since the codec resource release happens before the devm call chain, it triggers a NULL dereference or a UAF for a stale set_brightness_delay callback.

For fixing the bug, this patch changes the LED class device register and unregister in a manual manner without devres, keeping the instances in hda_gen_spec.

Summary
AIOHTTP: Out-of-bounds heap read in C HTTP response parser error path (malformed chunked response)
Details

Summary

An out-of-bounds heap read could occur in the C response parser while building an error message for a malformed response.

Impact

An attacker controlled server, or possibly an accidental response could trigger a DoS in the client.

Workaround

If unable to upgrade, the Python parser is unaffected and can be used with AIOHTTP_NO_EXTENSIONS=1.

Vulnerability from github – Published: 2025-06-26 21:31 – Updated: 2025-06-26 21:31
VLAI
Details

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.

Implementation

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.
