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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9841 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2022-02-19 00:01 – Updated: 2022-02-26 00:00This vulnerability allows remote attackers to execute arbitrary code on affected installations of Bentley MicroStation CONNECT 10.16.0.80. 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 DGN 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-15369.

GHSA-VFVV-C25P-M7MM
Vulnerability from github – Published: 2026-05-15 18:09 – Updated: 2026-05-15 18:09InlineVec::clear() and SerVec::clear() in rkyv were not panic-safe. Both functions iterate over their elements and call drop_in_place on each, updating self.len only after the loop. If an element's Drop implementation panics during the loop, self.len is left at its original value.
A subsequent invocation of clear() on the same container then re-visits the already-freed elements:
InlineVec::clear()is called again fromInlineVec's ownDropimplementation when the value is later dropped.SerVec::clear()is called again bySerVec::with_capacity()after the user closure returns.
Technical Impact
- CWE-415 (Double Free): Heap corruption when element type holds
Box<T> - CWE-416 (Use-After-Free): Memory corruption when element reads from heap during
Drop
Both vulnerabilities are triggerable entirely from safe Rust via std::panic::catch_unwind and require no special privileges.

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.
