Detailsinfo

A vulnerability classified as very critical was found in Eclipse ThreadX up to 6.5.2.202603. This vulnerability affects an unknown function of the component Trace Buffer Callback. The manipulation with an unknown input leads to a control flow vulnerability. The CWE definition for the vulnerability is CWE-670. The code contains a control flow path that does not reflect the algorithm that the path is intended to implement, leading to incorrect behavior any time this path is navigated. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

In Eclipse ThreadX versions 6.0.1 through 6.5.2.202603, ThreadX Modules does not revoke a module's trace-buffer-full callback when the module is stopped and unloaded. With event tracing enabled and a kernel-owned trace buffer still active, a later buffer wrap invokes the callback from privileged thread context after the module's code has been released, so a user-mode module can have its code run with kernel privileges after unload, or, once the memory is reused, redirect control flow or cause a fault.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-113421 since 10/20/2026. The exploitation appears to be easy. The attack needs to be approached locally. Additional levels of successful authentication are required for exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 11/03/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
