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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9901 vulnerabilities reference this CWE, most recent first.

Summary
pycares has a Use-After-Free Vulnerability
Details

Summary

pycares is vulnerable to a use-after-free condition that occurs when a Channel object is garbage collected while DNS queries are still pending. This results in a fatal Python error and interpreter crash.

Details

Root Cause

The vulnerability stems from improper handling of callback references when the Channel object is destroyed:

  1. When a DNS query is initiated, pycares stores a callback reference using ffi.new_handle()
  2. If the Channel object is garbage collected while queries are pending, the callback references become invalid
  3. When c-ares attempts to invoke the callback, it accesses freed memory, causing a fatal error

This issue was much more likely to occur when using event_thread=True but could happen without it under the right circumstances.

Technical Details

The core issue is a race condition between Python's garbage collector and c-ares's callback execution:

  1. When __del__ is called from within a c-ares callback context, we cannot immediately call ares_destroy() because c-ares is still executing code after the callback returns
  2. c-ares needs to execute cleanup code after our Python callback returns (specifically at lines 1422-1429 in ares_process.c)
  3. If we destroy the channel too quickly, c-ares accesses freed memory

Impact

Applications using pycares can be crashed remotely by triggering DNS queries that result in Channel objects being garbage collected before query completion. This is particularly problematic in scenarios where:

  • Channel objects are created per-request
  • Multiple failed DNS queries are processed rapidly
  • The application doesn't properly manage Channel lifecycle

The error manifests as:

Fatal Python error: b_from_handle: ffi.from_handle() detected that the address passed points to garbage

Fix

The vulnerability has been fixed in pycares 4.9.0 by implementing a safe channel destruction mechanism

Mitigation

For Application Developers

  1. Upgrade to pycares >= 4.9.0 - This version includes the fix and requires no code changes
  2. Best practices (optional but recommended): ```python # Explicit cleanup channel.close()

# Or use context manager with pycares.Channel() as channel: # ... use channel ... # Automatically closed ``` 3. Avoid creating Channel objects per-request - Prefer long-lived instances for better performance and safety

The fix is completely transparent - no API changes or code modifications are required.

This vulnerability was reported by @vEpiphyte through the aio-libs security program.

Vulnerability from github – Published: 2026-05-01 15:30 – Updated: 2026-05-03 09:33
VLAI
Details

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

wifi: virt_wifi: remove SET_NETDEV_DEV to avoid use-after-free

Currently we execute SET_NETDEV_DEV(dev, &priv->lowerdev->dev) for the virt_wifi net devices. However, unregistering a virt_wifi device in netdev_run_todo() can happen together with the device referenced by SET_NETDEV_DEV().

It can result in use-after-free during the ethtool operations performed on a virt_wifi device that is currently being unregistered. Such a net device can have the dev.parent field pointing to the freed memory, but ethnl_ops_begin() calls pm_runtime_get_sync(dev->dev.parent).

Let's remove SET_NETDEV_DEV for virt_wifi to avoid bugs like this:

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.
