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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9821 vulnerabilities reference this CWE, most recent first.

GHSA-6RW2-3PW4-264H

Vulnerability from github – Published: 2024-05-17 15:31 – Updated: 2025-09-19 18:31
VLAI
Details

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

dpll: fix pin dump crash for rebound module

When a kernel module is unbound but the pin resources were not entirely freed (other kernel module instance of the same PCI device have had kept the reference to that pin), and kernel module is again bound, the pin properties would not be updated (the properties are only assigned when memory for the pin is allocated), prop pointer still points to the kernel module memory of the kernel module which was deallocated on the unbind.

If the pin dump is invoked in this state, the result is a kernel crash. Prevent the crash by storing persistent pin properties in dpll subsystem, copy the content from the kernel module when pin is allocated, instead of using memory of the kernel module.

Vulnerability from github – Published: 2023-08-10 18:31 – Updated: 2023-11-05 12:30
VLAI
Details

A use-after-free flaw was found in net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in the Linux Kernel. This flaw allows a local attacker to perform a local privilege escalation due to incorrect handling of the existing filter, leading to a kernel information leak issue.

Details

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit Reader 9.5.0.20723. 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 exportValues method within a AcroForm. 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-8491.

GHSA-6V4R-GV8G-8W3C

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

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 9.0.1.1049. 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 Text Annotations. When setting the point attribute, the process does not properly validate the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code under the context of the current process. Was ZDI-CAN-5620.

GHSA-6V4X-GF5X-R6W5

Vulnerability from github – Published: 2025-10-04 18:31 – Updated: 2026-02-12 18:30
VLAI
Details

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

ip_vti: fix potential slab-use-after-free in decode_session6

When ip_vti device is set to the qdisc of the sfb type, the cb field of the sent skb may be modified during enqueuing. Then, slab-use-after-free may occur when ip_vti device sends IPv6 packets. As commit f855691975bb ("xfrm6: Fix the nexthdr offset in _decode_session6.") showed, xfrm_decode_session was originally intended only for the receive path. IP6CB(skb)->nhoff is not set during transmission. Therefore, set the cb field in the skb to 0 before sending packets.

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.
