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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
10904 vulnerabilities reference this CWE, most recent first.

GHSA-VXFF-46QF-F9JX
Vulnerability from github – Published: 2024-05-01 06:31 – Updated: 2024-12-23 15:30In the Linux kernel, the following vulnerability has been resolved:
bootconfig: use memblock_free_late to free xbc memory to buddy
On the time to free xbc memory in xbc_exit(), memblock may has handed over memory to buddy allocator. So it doesn't make sense to free memory back to memblock. memblock_free() called by xbc_exit() even causes UAF bugs on architectures with CONFIG_ARCH_KEEP_MEMBLOCK disabled like x86. Following KASAN logs shows this case.
This patch fixes the xbc memory free problem by calling memblock_free() in early xbc init error rewind path and calling memblock_free_late() in xbc exit path to free memory to buddy allocator.

GHSA-VXRQ-58Q3-4WX5
Vulnerability from github – Published: 2023-11-16 15:30 – Updated: 2023-11-16 15:30Adobe Bridge versions 13.0.4 (and earlier) and 14.0.0 (and earlier) are affected by a Use After Free vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

GHSA-VXVF-4CM8-PMG9
Vulnerability from github – Published: 2024-07-29 15:30 – Updated: 2025-11-04 00:31In the Linux kernel, the following vulnerability has been resolved:
cachefiles: Set object to close if ondemand_id < 0 in copen
If copen is maliciously called in the user mode, it may delete the request corresponding to the random id. And the request may have not been read yet.
Note that when the object is set to reopen, the open request will be done with the still reopen state in above case. As a result, the request corresponding to this object is always skipped in select_req function, so the read request is never completed and blocks other process.
Fix this issue by simply set object to close if its id < 0 in copen.

GHSA-VXXJ-38M8-46GM
Vulnerability from github – Published: 2023-11-27 18:31 – Updated: 2025-11-04 21:30A use-after-free vulnerability exists in the way Foxit Reader 12.1.2.15356 handles a signature field. A specially crafted Javascript code inside a malicious PDF document can trigger reuse of a previously freed object, which can lead to memory corruption and result in 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.

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.
