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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
10952 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2026-05-27 15:33 – Updated: 2026-05-30 12:30In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Stop job scheduling across aie2_release_resource()
Running jobs on a hardware context while it is in the process of releasing resources can lead to use-after-free and crashes.
Fix this by stopping job scheduling before calling aie2_release_resource() and restarting it after the release completes. Additionally, aie2_sched_job_run() now checks whether the hardware context is still active.

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Foxit PDF Reader. 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 processing of AcroForms. The issue results from the lack of validating the existence of an object prior to performing operations on the object.

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.
