CVE-2025-55078

System crash via invalid kernel object pointers

Published Oct 14, 2025 · Updated Oct 14, 2025

Improper parameter handling in Eclipse ThreadX before 6.4.3 allows local users to crash the system through crafted kernel object pointers. The TXM_MODULE_MANAGER_PARAM_CHECK_OBJECT_FOR_USE macro accepts pointers outside module memory without confirming that they reference mapped kernel objects. A low-privileged untrusted module must invoke an affected system call; dereferencing reserved memory triggers a HardFault or BusFault and stops the system until reboot.
