CVE-2026-118052
Module Manager loaders leave the manager mutex held when a module preamble's sizes overflow, blocking every later module operation
Description

In Eclipse ThreadX versions 6.0.1 through 6.5.2.202603, the Module Manager loaders return an overflow error without releasing the Module Manager mutex when a module preamble declares a data or stack size that overflows the allocation arithmetic. Loading such an image blocks every later module load, start, stop and unload from other threads until the system is reset.
