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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9854 vulnerabilities reference this CWE, most recent first.

GHSA-45C3-PWCH-8QG9

Vulnerability from github – Published: 2025-02-27 18:31 – Updated: 2025-02-27 18:31
VLAI
Details

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

ALSA: pcm: Fix races among concurrent hw_params and hw_free calls

Currently we have neither proper check nor protection against the concurrent calls of PCM hw_params and hw_free ioctls, which may result in a UAF. Since the existing PCM stream lock can't be used for protecting the whole ioctl operations, we need a new mutex to protect those racy calls.

This patch introduced a new mutex, runtime->buffer_mutex, and applies it to both hw_params and hw_free ioctl code paths. Along with it, the both functions are slightly modified (the mmap_count check is moved into the state-check block) for code simplicity.

Severity
7.8 (High)

GHSA-45CM-4V3W-5JPW

Vulnerability from github – Published: 2024-05-14 15:32 – Updated: 2026-01-22 21:33
VLAI
Details

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

Bluetooth: Fix use-after-free bugs caused by sco_sock_timeout

When the sco connection is established and then, the sco socket is releasing, timeout_work will be scheduled to judge whether the sco disconnection is timeout. The sock will be deallocated later, but it is dereferenced again in sco_sock_timeout. As a result, the use-after-free bugs will happen. The root cause is shown below:

Cleanup Thread               |      Worker Thread

sco_sock_release | sco_sock_close | __sco_sock_close | sco_sock_set_timer | schedule_delayed_work | sco_sock_kill | (wait a time) sock_put(sk) //FREE | sco_sock_timeout | sock_hold(sk) //USE

The KASAN report triggered by POC is shown below:

Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2026-04-18 09:30
VLAI
Details

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

ksmbd: Fix dangling pointer in krb_authenticate

krb_authenticate frees sess->user and does not set the pointer to NULL. It calls ksmbd_krb5_authenticate to reinitialise sess->user but that function may return without doing so. If that happens then smb2_sess_setup, which calls krb_authenticate, will be accessing free'd memory when it later uses sess->user.

Severity
7.8 (High)

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

When remove the module peek_pci, referencing 'chan' again after releasing 'dev' will cause UAF.

Fix this by releasing 'dev' later.

The following log reveals it:

VLAI
Details

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PhantomPDF 10.1.0.37527. 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 U3D objects in PDF files. 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-12295.

GHSA-45VP-VX4C-9JR2

Vulnerability from github – Published: 2024-07-16 12:30 – Updated: 2024-08-21 18:31
VLAI
Details

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

net: mscc: ocelot: fix use-after-free in ocelot_vlan_del()

ocelot_vlan_member_del() will free the struct ocelot_bridge_vlan, so if this is the same as the port's pvid_vlan which we access afterwards, what we're accessing is freed memory.

Fix the bug by determining whether to clear ocelot_port->pvid_vlan prior to calling ocelot_vlan_member_del().

Severity
7.8 (High)
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

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.
