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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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

Vulnerability from github – Published: 2024-05-03 03:30 – Updated: 2024-05-03 03:30Sante DICOM Viewer Pro DCM File Parsing Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Sante DICOM Viewer Pro. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of DCM images. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-15629.

Vulnerability from github – Published: 2023-07-19 15:30 – Updated: 2024-04-04 06:16A use-after-free vulnerability exists in the JavaScript engine of Foxit Software's PDF Reader, version 12.1.1.15289. A specially crafted PDF document can trigger the reuse of previously freed memory by manipulating form fields of a specific type. This can lead to memory corruption and arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

Vulnerability from github – Published: 2024-05-21 18:31 – Updated: 2024-10-31 18:31In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix dfs-radar and temperature event locking
The ath12k active pdevs are protected by RCU but the DFS-radar and temperature event handling code calling ath12k_mac_get_ar_by_pdev_id() was not marked as a read-side critical section.
Mark the code in question as RCU read-side critical sections to avoid any potential use-after-free issues.
Note that the temperature event handler looks like a place holder currently but would still trigger an RCU lockdep splat.
Compile tested only.

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.
