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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9813 vulnerabilities reference this CWE, most recent first.

GHSA-28CG-R647-J4CW

Vulnerability from github – Published: 2024-02-28 09:30 – Updated: 2024-12-06 15:31
VLAI
Details

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

ethernet:enic: Fix a use after free bug in enic_hard_start_xmit

In enic_hard_start_xmit, it calls enic_queue_wq_skb(). Inside enic_queue_wq_skb, if some error happens, the skb will be freed by dev_kfree_skb(skb). But the freed skb is still used in skb_tx_timestamp(skb).

My patch makes enic_queue_wq_skb() return error and goto spin_unlock() incase of error. The solution is provided by Govind. See https://lkml.org/lkml/2021/4/30/961.

Severity
7.8 (High)

Mitigation
Architecture and Design

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.
