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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9874 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2024-12-27 15:31 – Updated: 2025-01-14 15:30In the Linux kernel, the following vulnerability has been resolved:
PCI: endpoint: Fix PCI domain ID release in pci_epc_destroy()
pci_epc_destroy() invokes pci_bus_release_domain_nr() to release the PCI domain ID, but there are two issues:
-
'epc->dev' is passed to pci_bus_release_domain_nr() which was already freed by device_unregister(), leading to a use-after-free issue.
-
Domain ID corresponds to the EPC device parent, so passing 'epc->dev' is also wrong.
Fix these issues by passing 'epc->dev.parent' to pci_bus_release_domain_nr() and also do it before device_unregister().

The root cause is that the tail pcluster won't be a complete filesystem
block anymore. So if ztailpacking is used, the second part of an
uncompressed tail pcluster may not be rq->pageofs_out.

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.
