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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9843 vulnerabilities reference this CWE, most recent first.
GHSA-J8CJ-HW74-64JV
Vulnerability from github – Published: 2026-02-28 02:48 – Updated: 2026-02-28 02:48Drop implementation for Hive did perform free, but so did Hive::close, which, at the end of the scope performed Drop, therefore triggering double-free.
Additionally, function Hive::from_handle was not marked as unsafe, making it, in combination with as_handle easy to clone and trigger double-free in safe code or triggering UB when using invalid pointer.

GHSA-J8G4-37FG-MJM8
Vulnerability from github – Published: 2025-09-22 21:30 – Updated: 2025-12-12 21:31In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: vhci: Prevent use-after-free by removing debugfs files early
Move the creation of debugfs files into a dedicated function, and ensure they are explicitly removed during vhci_release(), before associated data structures are freed.
Previously, debugfs files such as "force_suspend", "force_wakeup", and others were created under hdev->debugfs but not removed in vhci_release(). Since vhci_release() frees the backing vhci_data structure, any access to these files after release would result in use-after-free errors.
Although hdev->debugfs is later freed in hci_release_dev(), user can access files after vhci_data is freed but before hdev->debugfs is released.

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.
