Detailsinfo

A vulnerability has been found in Eclipse ThreadX up to 6.5.1.202602a and classified as very critical. Affected by this vulnerability is the function txm_module_object_deallocate of the component Module Manager. The manipulation with an unknown input leads to a use after free vulnerability. The CWE definition for the vulnerability is CWE-416. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

A ThreadX module allocates the control blocks of its kernel objects from the Module Manager's object pool, and can ask for that memory back by address with `txm_module_object_deallocate`. The manager released it whatever was in it, including a control block the kernel was still using. Deallocation is not deletion: the object stays on the created list for its type, a thread stays wherever it was on the ready or suspension lists and stays schedulable, and an active timer stays on the timer list. The byte pool is meanwhile free to hand those same bytes to the next allocation.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-94192 since 09/23/2026. The exploitation appears to be easy. The attack can be launched remotely. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 10/20/2026).
