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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
10815 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2025-05-10 15:30 – Updated: 2025-11-12 21:31In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btsdio: fix use after free bug in btsdio_remove due to race condition
In btsdio_probe, the data->work is bound with btsdio_work. It will be started in btsdio_send_frame.
If the btsdio_remove runs with a unfinished work, there may be a race condition that hdev is freed but used in btsdio_work. Fix it by canceling the work before do cleanup in btsdio_remove.

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.
