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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9821 vulnerabilities reference this CWE, most recent first.

GHSA-Q73C-HQQP-JCP7

Vulnerability from github – Published: 2024-12-27 15:31 – Updated: 2025-01-14 15:30
VLAI
Details

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

PCI: endpoint: Fix PCI domain ID release in pci_epc_destroy()

pci_epc_destroy() invokes pci_bus_release_domain_nr() to release the PCI domain ID, but there are two issues:

  • 'epc->dev' is passed to pci_bus_release_domain_nr() which was already freed by device_unregister(), leading to a use-after-free issue.

  • Domain ID corresponds to the EPC device parent, so passing 'epc->dev' is also wrong.

Fix these issues by passing 'epc->dev.parent' to pci_bus_release_domain_nr() and also do it before device_unregister().

Details

A use-after-free vulnerability exists in the DICOM Element Parsing as implemented in Imaging Data Commons libdicom 1.0.5. A specially crafted DICOM file can cause premature freeing of memory that is used later. To trigger this vulnerability, an attacker would need to induce the vulnerable application to process a malicious DICOM image.The Use-After-Free happens in the parse_meta_sequence_end() parsing the Sequence Value Represenations.

Details

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader 11.2.1.53537. 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 Doc objects. 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-16805.
