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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
11148 vulnerabilities reference this CWE, most recent first.
GHSA-3JPP-F2WM-PCVV
Vulnerability from github – Published: 2026-02-14 18:30 – Updated: 2026-06-30 03:35In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mld: cancel mlo_scan_start_wk
mlo_scan_start_wk is not canceled on disconnection. In fact, it is not canceled anywhere except in the restart cleanup, where we don't really have to.
This can cause an init-after-queue issue: if, for example, the work was queued and then drv_change_interface got executed.
This can also cause use-after-free: if the work is executed after the vif is freed.

Vulnerability from github – Published: 2022-05-24 16:57 – Updated: 2024-04-04 02:08This vulnerability allows remote atackers to execute arbitrary code on affected installations of Foxit PhantomPDF 9.5.0.20723. 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 Calculate actions. 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-8757.

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.
