Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
模块管理器在对象查找时，仅对受内存保护模块的搜索名称验证了一个字节，随后便以特权模式、并在提升内核抢占计数（preemption count）的情况下，遍历了该模块声明的整个名称长度。两个查找分发器均受影响：推荐的 函数接收一个长度参数，却未利用该参数对缓冲区进行边界限制；而已过时的 函数则传入 类型所能表示的最大值，从而实质上移除了边界限制，而非仅仅缺少边界检查。 恶意模块可在无需了解所触及内存内容的情况下，使遍历过程变为无界。当遍历触及到特权模式下无法读取的内存区域时，会触发异常，导致内核无法再执行抢占操作，从

Vulnerability Title
Module Manager object lookup validates one byte of a module's search name
Source: CVE Program / CVE List V5
Vulnerability 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`).
