CVE-2026-94024

Description

The Module Manager's object lookup validated one byte of a memory-protected module's search name and then walked as much of it as the module declared, in privileged mode, with the kernel's preemption count raised. Both lookup dispatchers are affected: the recommended `txm_module_object_pointer_get_extended` is handed a length and does not use it to bound the buffer, and the deprecated `txm_module_object_pointer_get` supplies the largest value a `UINT` can hold, so it removes the bound rather than lacking one. A module can make the walk unbounded without knowing anything about the memory it reaches, and where the walk reaches memory a privileged read cannot take, the resulting fault leaves the kernel unable to preempt for the rest of the system's life. Vulnerable functions: `_txm_module_manager_txm_module_object_pointer_get_dispatch`, `_txm_module_manager_txm_module_object_pointer_get_extended_dispatch` (both in `common_modules/module_manager/inc/txm_module_manager_dispatch.h`) and `_txm_module_manager_object_name_compare` (`common_modules/module_manager/src/txm_module_manager_util.c`).
