Common Weakness Enumeration

CWE-416

Allowed

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

11157 vulnerabilities reference this CWE, most recent first.

GHSA-PR76-FCF6-2XG3

Vulnerability from github – Published: 2025-09-05 18:31 – Updated: 2025-11-25 21:32
VLAI
Details

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

media: ivsc: Fix crash at shutdown due to missing mei_cldev_disable() calls

Both the ACE and CSI driver are missing a mei_cldev_disable() call in their remove() function.

This causes the mei_cl client to stay part of the mei_device->file_list list even though its memory is freed by mei_cl_bus_dev_release() calling kfree(cldev->cl).

This leads to a use-after-free when mei_vsc_remove() runs mei_stop() which first removes all mei bus devices calling mei_ace_remove() and mei_csi_remove() followed by mei_cl_bus_dev_release() and then calls mei_cl_all_disconnect() which walks over mei_device->file_list dereferecing the just freed cldev->cl.

And mei_vsc_remove() it self is run at shutdown because of the platform_device_unregister(tp->pdev) in vsc_tp_shutdown()

When building a kernel with KASAN this leads to the following KASAN report:

A use-after-free related to unsound inference in the bytecode generation when optimizations are enabled for Hermes prior to commit da8990f737ebb9d9810633502f65ed462b819c09 could have been used by an attacker to achieve remote code execution. Note that this is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Hence, most React Native applications are not affected.

Vulnerability from github – Published: 2022-09-16 00:00 – Updated: 2022-09-20 00:00
VLAI
Details

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ansys SpaceClaim 2022 R1. 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 JT files. 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-17045.
