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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

11090 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2024-12-27 15:31 – Updated: 2025-11-03 21:31
VLAI
Details

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

SUNRPC: make sure cache entry active before cache_show

The function c_show was called with protection from RCU. This only ensures that cp will not be freed. Therefore, the reference count for cp can drop to zero, which will trigger a refcount use-after-free warning when cache_get is called. To resolve this issue, use cache_get_rcu to ensure that cp remains active.

Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-08 15:31
VLAI
Details

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

netfilter: nfnetlink_queue: make hash table per queue

Sharing a global hash table among all queues is tempting, but it can cause crash:

BUG: KASAN: slab-use-after-free in nfqnl_recv_verdict+0x11ac/0x15e0 [nfnetlink_queue] [..] nfqnl_recv_verdict+0x11ac/0x15e0 [nfnetlink_queue] nfnetlink_rcv_msg+0x46a/0x930 kmem_cache_alloc_node_noprof+0x11e/0x450

struct nf_queue_entry is freed via kfree, but parallel cpu can still encounter such an nf_queue_entry when walking the list.

Alternative fix is to free the nf_queue_entry via kfree_rcu() instead, but as we have to alloc/free for each skb this will cause more mem pressure.

GHSA-323W-VCFF-W7MP

Vulnerability from github – Published: 2022-05-24 16:59 – Updated: 2024-04-04 02:34
VLAI
Details

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PhantomPDF 9.6.0.25114. 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 processing of script within a Keystroke action of a listbox field. 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-9081.
