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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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

CVE-2011-10034 (GCVE-0-2011-10034)

Vulnerability from cvelistv5 – Published: 2025-11-12 22:08 – Updated: 2026-05-14 02:06

Title
IRAI AUTOMGEN <= 8.0.0.7 Use-After-Free Remote DoS
Summary
AUTOMGEN versions up to and including 8.0.0.7 (also referenced as 8.022) contain a vulnerability in that project file handling frees an object and subsequently dereferences the stale pointer when processing certain malformed fields. The dangling-pointer use enables an attacker to influence an indirect call through attacker-controlled memory, resulting in denial-of-service. In some conditions, remote code execution may be possible.

Vulnerability from github – Published: 2023-02-28 15:30 – Updated: 2023-03-10 06:30
VLAI
Details

There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is created from the listener, the context is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c

GHSA-2252-87PV-34G4

Vulnerability from github – Published: 2024-04-04 09:30 – Updated: 2024-12-20 18:31
VLAI
Details

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

Bluetooth: Avoid potential use-after-free in hci_error_reset

While handling the HCI_EV_HARDWARE_ERROR event, if the underlying BT controller is not responding, the GPIO reset mechanism would free the hci_dev and lead to a use-after-free in hci_error_reset.

Here's the call trace observed on a ChromeOS device with Intel AX201: queue_work_on+0x3e/0x6c __hci_cmd_sync_sk+0x2ee/0x4c0 [bluetooth ] ? init_wait_entry+0x31/0x31 __hci_cmd_sync+0x16/0x20 [bluetooth ] hci_error_reset+0x4f/0xa4 [bluetooth ] process_one_work+0x1d8/0x33f worker_thread+0x21b/0x373 kthread+0x13a/0x152 ? pr_cont_work+0x54/0x54 ? kthread_blkcg+0x31/0x31 ret_from_fork+0x1f/0x30

This patch holds the reference count on the hci_dev while processing a HCI_EV_HARDWARE_ERROR event to avoid potential crash.

Vulnerability from github – Published: 2023-07-06 19:24 – Updated: 2024-04-04 05:35

Details

A use-after-free flaw was found in the Linux kernel’s Ext4 File System in how a user triggers several file operations simultaneously with the overlay FS usage. This flaw allows a local user to crash or potentially escalate their privileges on the system. Only if patch 9a2544037600 ("ovl: fix use after free in struct ovl_aio_req") not applied yet, the kernel could be affected.

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.
