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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9831 vulnerabilities reference this CWE, most recent first.

Details

WebRTC can use a "WrappedI420Buffer" pixel buffer but the owning image object can be freed while it is still in use. This can result in the WebRTC encoder using uninitialized memory, leading to a potentially exploitable crash. This vulnerability affects Firefox < 60.

GHSA-H976-GQWV-338W

Vulnerability from github – Published: 2026-01-15 21:31 – Updated: 2026-01-15 21:31
VLAI
Details

A Use After Free vulnerability was identified in the 802.1X authentication daemon (dot1xd) of Juniper Networks Junos OS and Junos OS Evolved that could allow an authenticated, network-adjacent attacker flapping a port to crash the dot1xd process, leading to a Denial of Service (DoS), or potentially execute arbitrary code within the context of the process running as root.

The issue is specific to the processing of a change in authorization (CoA) when a port bounce occurs. A pointer is freed but was then referenced later in the same code path. Successful exploitation is outside the attacker's direct control due to the specific timing of the two events required to execute the vulnerable code path.

This issue affects systems with 802.1X authentication port-based network access control (PNAC) enabled. This issue affects:

Junos OS: 

  • from 23.2R2-S1 before 23.2R2-S5, 
  • from 23.4R2 before 23.4R2-S6, 
  • from 24.2 before 24.2R2-S3, 
  • from 24.4 before 24.4R2-S1, 
  • from 25.2 before 25.2R1-S2, 25.2R2; 

Junos OS Evolved: 

  • from 23.2R2-S1 before 23.2R2-S5-EVO, 
  • from 23.4R2 before 23.4R2-S6-EVO, 
  • from 24.2 before 24.2R2-S3-EVO, 
  • from 24.4 before 24.4R2-S1-EVO, 
  • from 25.2 before 25.2R1-S2-EVO, 25.2R2-EVO.

GHSA-H999-3QM9-V2XM

Vulnerability from github – Published: 2024-07-30 09:31 – Updated: 2025-10-07 18:31
VLAI
Details

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

net: txgbe: free isb resources at the right time

When using MSI/INTx interrupt, the shared interrupts are still being handled in the device remove routine, before free IRQs. So isb memory is still read after it is freed. Thus move wx_free_isb_resources() from txgbe_close() to txgbe_remove(). And fix the improper isb free action in txgbe_open() error handling path.

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.
