Common Weakness Enumeration
CWE-416
AllowedUse 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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9874 vulnerabilities reference this CWE, most recent first.

Tungsten Automation Power PDF JP2 File Parsing Use-After-Free Information Disclosure Vulnerability
Summary
Tungsten Automation Power PDF JP2 File Parsing Use-After-Free Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Tungsten Automation Power PDF. 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 JP2 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-25564.

Title
Reference counting in php_request_shutdown causes Use-After-Free
Summary
In PHP versions 8.3.* before 8.3.19 and 8.4.* before 8.4.5, a code sequence involving __set handler or ??= operator and exceptions can lead to a use-after-free vulnerability. If the third party can control the memory layout leading to this, for example by supplying specially crafted inputs to the script, it could lead to remote code execution.

Title
Rockwell Automation Arena® Use After Free Vulnerability
Summary
A “use after free” code execution vulnerability exists in the Rockwell Automation Arena® that could allow a threat actor to craft a DOE file and force the software to use a resource that was already used. If exploited, a threat actor could leverage this vulnerability to execute arbitrary code. To exploit this vulnerability, a legitimate user must execute the malicious code crafted by the threat actor.
