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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
11158 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2024-09-18 09:30 – Updated: 2024-09-23 18:30
VLAI
Details
In the Linux kernel, the following vulnerability has been resolved:
xen: privcmd: Fix possible access to a freed kirqfd instance
Nothing prevents simultaneous ioctl calls to privcmd_irqfd_assign() and privcmd_irqfd_deassign(). If that happens, it is possible that a kirqfd created and added to the irqfds_list by privcmd_irqfd_assign() may get removed by another thread executing privcmd_irqfd_deassign(), while the former is still using it after dropping the locks.
This can lead to a situation where an already freed kirqfd instance may be accessed and cause kernel oops.
Use SRCU locking to prevent the same, as is done for the KVM implementation for irqfds.

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.
