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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9821 vulnerabilities reference this CWE, most recent first.

"value": "A weakness has been identified in radareorg radare2 up to 6.1.6. Impacted is the function r_core_seek_arch_bits of the file libr/core/disasm.c of the component regprofile Handler. Executing a manipulation can lead to use after free. The attack requires local access. The exploit has been made available to the public and could be used for attacks. This patch is called 8b25c773785d85cb0103410a0905089d286921c2. It is advisable to implement a patch to correct this issue."

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.
