CVE-2026-118052

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

Published Nov 2, 2026 CVSS 4.0 · 6.8 Medium EPSS < 1% KEV · Not listed
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.
