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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9821 vulnerabilities reference this CWE, most recent first.
GHSA-VPCV-78CP-WHR3
Vulnerability from github – Published: 2022-05-13 01:48 – Updated: 2022-11-01 22:59When handling a libprocess message wrapped in an HTTP request, libprocess in Apache Mesos before 1.1.3, 1.2.x before 1.2.2, 1.3.x before 1.3.1, and 1.4.0-dev crashes if the request path is empty, because the parser assumes the request path always starts with '/'. A malicious actor can therefore cause a denial of service of Mesos masters rendering the Mesos-controlled cluster inoperable.

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 PDF 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 vulnerability to execute code in the context of the current process. Was ZDI-CAN-15463.

Vulnerability from github – Published: 2022-05-14 01:14 – Updated: 2025-04-20 03:39In Netwide Assembler (NASM) 2.14rc0, there are multiple heap use after free vulnerabilities in the tool nasm. The related heap is allocated in the token() function and freed in the detoken() function (called by pp_getline()) - it is used again at multiple positions later that could cause multiple damages. For example, it causes a corrupted double-linked list in detoken(), a double free or corruption in delete_Token(), and an out-of-bounds write in detoken(). It has a high possibility to lead to a remote code execution attack.

Mitigation
Strategy: Language Selection
Choose a language that provides automatic memory management.
Mitigation
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.
No CAPEC attack patterns related to this CWE.
