Common Weakness Enumeration

CWE-416

Allowed

Use After Free

Abstraction: Variant · Status: Stable

API response cwe.mitre.org

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

10190 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2024-03-06 09:30 – Updated: 2025-01-07 21:30
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

llc: call sock_orphan() at release time

syzbot reported an interesting trace [1] caused by a stale sk->sk_wq pointer in a closed llc socket.

In commit ff7b11aa481f ("net: socket: set sock->sk to NULL after calling proto_ops::release()") Eric Biggers hinted that some protocols are missing a sock_orphan(), we need to perform a full audit.

In net-next, I plan to clear sock->sk from sock_orphan() and amend Eric patch to add a warning.

Vulnerability from github – Published: 2022-05-13 01:33 – Updated: 2022-05-13 01:33
VLAI
Details

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 9.2.0.9297. 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 handling of the respose property of a host object. 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-6509.

Vulnerability from github – Published: 2025-12-11 18:30 – Updated: 2025-12-11 21:31
VLAI
Details

An issue was discovered in Foxit PDF and Editor for Windows before 13.2 and 2025 before 2025.2. A crafted PDF containing JavaScript that calls closeDoc() while internal objects are still in use can cause premature release of these objects. This use-after-free vulnerability may lead to memory corruption, potentially resulting in information disclosure when the PDF is opened.

Severity
6.7 (Medium)

GHSA-9V4W-R8XW-999H

Vulnerability from github – Published: 2025-08-22 15:33 – Updated: 2026-01-07 18:30
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

vsock: Do not allow binding to VMADDR_PORT_ANY

It is possible for a vsock to autobind to VMADDR_PORT_ANY. This can cause a use-after-free when a connection is made to the bound socket. The socket returned by accept() also has port VMADDR_PORT_ANY but is not on the list of unbound sockets. Binding it will result in an extra refcount decrement similar to the one fixed in fcdd2242c023 (vsock: Keep the binding until socket destruction).

Modify the check in __vsock_bind_connectible() to also prevent binding to VMADDR_PORT_ANY.

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.
