Common Weakness Enumeration

CWE-416

Allowed

Use After Free

Abstraction: Variant · Status: Stable

API response cwe.mitre.org

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

11078 vulnerabilities reference this CWE, most recent first.

Details

In the Linux kernel, the following vulnerability has been resolved:

spi: imx: fix use-after-free on unbind

The SPI subsystem frees the controller and any subsystem allocated driver data as part of deregistration (unless the allocation is device managed).

Take another reference before deregistering the controller so that the driver data is not freed until the driver is done with it.

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.
