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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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

GHSA-JMMM-PCPP-RRC4
Vulnerability from github – Published: 2024-03-06 09:30 – Updated: 2024-08-06 15:30In the Linux kernel, the following vulnerability has been resolved:
spmi: mediatek: Fix UAF on device remove
The pmif driver data that contains the clocks is allocated along with spmi_controller. On device remove, spmi_controller will be freed first, and then devres , including the clocks, will be cleanup. This leads to UAF because putting the clocks will access the clocks in the pmif driver data, which is already freed along with spmi_controller.
This can be reproduced by enabling DEBUG_TEST_DRIVER_REMOVE and building the kernel with KASAN.
Fix the UAF issue by using unmanaged clk_bulk_get() and putting the clocks before freeing spmi_controller.

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.
