Common Weakness Enumeration

CWE-416

Allowed

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9874 vulnerabilities reference this CWE, most recent first.

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

mailbox: mailbox-test: free channels on probe error

On probe error, free the previously obtained channels. This not only prevents a leak, but also UAF scenarios because the client structure will be removed nonetheless because it was allocated with devm.

GHSA-H63C-9R2V-9CMW

Vulnerability from github – Published: 2026-05-27 15:33 – Updated: 2026-06-24 18:32
VLAI
Details

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

power: supply: bq256xx: Fix use-after-free in power_supply_changed()

Using the devm_ variant for requesting IRQ before the devm_ variant for allocating/registering the power_supply handle, means that the power_supply handle will be deallocated/unregistered before the interrupt handler (since devm_ naturally deallocates in reverse allocation order). This means that during removal, there is a race condition where an interrupt can fire just after the power_supply handle has been freed, but just before the corresponding unregistration of the IRQ handler has run.

This will lead to the IRQ handler calling power_supply_changed() with a freed power_supply handle. Which usually crashes the system or otherwise silently corrupts the memory...

Note that there is a similar situation which can also happen during probe(); the possibility of an interrupt firing before registering the power_supply handle. This would then lead to the nasty situation of using the power_supply handle uninitialized in power_supply_changed().

Fix this racy use-after-free by making sure the IRQ is requested after the registration of the power_supply handle.

GHSA-H66W-323G-4Q62

Vulnerability from github – Published: 2022-08-26 00:03 – Updated: 2025-02-28 15:30
VLAI
Details

A DMA reentrancy issue was found in the NVM Express Controller (NVME) emulation in QEMU. This CVE is similar to CVE-2021-3750 and, just like it, when the reentrancy write triggers the reset function nvme_ctrl_reset(), data structs will be freed leading to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition or, potentially, executing arbitrary code within the context of the QEMU process on the host.

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.

No CAPEC attack patterns related to this CWE.
