CWE-416
AllowedUse After Free
Abstraction: Variant · Status: Stable
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
11157 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2024-06-20 12:31 – Updated: 2024-08-19 18:32In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda: Fix UAF of leds class devs at unbinding
The LED class devices that are created by HD-audio codec drivers are registered via devm_led_classdev_register() and associated with the HD-audio codec device. Unfortunately, it turned out that the devres release doesn't work for this case; namely, since the codec resource release happens before the devm call chain, it triggers a NULL dereference or a UAF for a stale set_brightness_delay callback.
For fixing the bug, this patch changes the LED class device register and unregister in a manual manner without devres, keeping the instances in hda_gen_spec.

GHSA-CQ5V-8Q36-5273
Vulnerability from github – Published: 2026-08-03 20:51 – Updated: 2026-08-03 20:51Summary
An out-of-bounds heap read could occur in the C response parser while building an error message for a malformed response.
Impact
An attacker controlled server, or possibly an accidental response could trigger a DoS in the client.
Workaround
If unable to upgrade, the Python parser is unaffected and can be used with AIOHTTP_NO_EXTENSIONS=1.

Mitigation
Strategy: Language Selection
Choose a language that provides automatic memory management.
Mitigation
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.
No CAPEC attack patterns related to this CWE.
