Summary

Eclipse ThreadX versions 6.0.1 through 6.5.2.202603 do not revoke a module's trace-buffer-full callback when the module is stopped and unloaded (CWE-416). 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. A user-mode module can therefore have its code run with kernel privileges after unload, or, once the memory is reused, redirect control flow or cause a fault.

Description from the CNA

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.
