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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9811 vulnerabilities reference this CWE, most recent first.

Details

Foxit PDF Editor Polygon Annotation Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Editor. 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 Annotation objects. 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-14366.

GHSA-23X6-W5Q4-2MQW

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:

net: defer final 'struct net' free in netns dismantle

Ilya reported a slab-use-after-free in dst_destroy [1]

Issue is in xfrm6_net_init() and xfrm4_net_init() :

They copy xfrm[46]_dst_ops_template into net->xfrm.xfrm[46]_dst_ops.

But net structure might be freed before all the dst callbacks are called. So when dst_destroy() calls later :

if (dst->ops->destroy) dst->ops->destroy(dst);

dst->ops points to the old net->xfrm.xfrm[46]_dst_ops, which has been freed.

See a relevant issue fixed in :

ac888d58869b ("net: do not delay dst_entries_add() in dst_release()")

A fix is to queue the 'struct net' to be freed after one another cleanup_net() round (and existing rcu_barrier())

[1]

Vulnerability from github – Published: 2022-05-24 16:59 – Updated: 2026-06-09 10:22

Summary
Nokogiri affected by libxslt Use of Uninitialized Resource/Use After Free vulnerability
Details

In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed.

Nokogiri prior to version 1.10.5 contains a vulnerable version of libxslt. Nokogiri version 1.10.5 upgrades the dependency to libxslt 1.1.34, which contains a patch for this issue.

GHSA-249V-WMCW-XVGM

Vulnerability from github – Published: 2026-05-01 15:30 – Updated: 2026-05-07 21:30
VLAI
Details

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

HID: logitech-hidpp: Prevent use-after-free on force feedback initialisation failure

Presently, if the force feedback initialisation fails when probing the Logitech G920 Driving Force Racing Wheel for Xbox One, an error number will be returned and propagated before the userspace infrastructure (sysfs and /dev/input) has been torn down. If userspace ignores the errors and continues to use its references to these dangling entities, a UAF will promptly follow.

We have 2 options; continue to return the error, but ensure that all of the infrastructure is torn down accordingly or continue to treat this condition as a warning by emitting the message but returning success. It is thought that the original author's intention was to emit the warning but keep the device functional, less the force feedback feature, so let's go with that.

Severity
7.8 (High)

  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: logitech-hidpp: Prevent use-after-free on force feedback initialisation failure\n\nPresently, if the force feedback initialisation fails when probing the\nLogitech G920 Driving Force Racing Wheel for Xbox One, an error number\nwill be returned and propagated before the userspace infrastructure\n(sysfs and /dev/input) has been torn down.  If userspace ignores the\nerrors and continues to use its references to these dangling entities, a\nUAF will promptly follow.\n\nWe have 2 options; continue to return the error, but ensure that all of\nthe infrastructure is torn down accordingly or continue to treat this\ncondition as a warning by emitting the message but returning success.\nIt is thought that the original author\u0027s intention was to emit the\nwarning but keep the device functional, less the force feedback feature,\nso let\u0027s go with that.",

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.
