Common Weakness Enumeration
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
10001 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2025-02-27 18:31 – Updated: 2025-02-27 18:31
VLAI
Details
In the Linux kernel, the following vulnerability has been resolved:
crypto: ccree - Fix use after free in cc_cipher_exit()
kfree_sensitive(ctx_p->user.key) will free the ctx_p->user.key. But ctx_p->user.key is still used in the next line, which will lead to a use after free.
We can call kfree_sensitive() after dev_dbg() to avoid the uaf.

Mitigation
Architecture and Design
Strategy: Language Selection
Choose a language that provides automatic memory management.
Mitigation
Implementation
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.
