CVE-2026-94202— Module block-pool create validates two of the four parameter words it reads
Quick assessment
Affected
Eclipse Foundation Eclipse ThreadX
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（Module Manager）的块池（block-pool）创建分发器（dispatcher）仅验证了模块提供的额外参数数组中的两个 类型字位于该受内存保护模块的数据区域内，随后却使用了该数组的索引 0 至 3。 其中，未被验证的一个字会被分发器自身的缓冲区检查逻辑读取：该检查将索引 1 视为池起始地址，将索引 2 视为长度，并据此进行范围检查。因此，越界读取实际上是由验证代码自身在调用内核服务之前执行的；而用于验证调用方池起始地址大小的那个字，却是管理器并未证明模块拥有所有权的字。另一个未被验证的字则

Vulnerability Title
Module block-pool create validates two of the four parameter words it reads
Source: CVE Program / CVE List V5
Vulnerability Description
The Module Manager's block-pool create dispatcher proved that two `ALIGN_TYPE` words of the extra-parameter array a memory-protected module supplies lay inside the module's data, and then used indices 0 through 3 of that array.
One of the two unproved words is read by the dispatcher's own buffer check, which takes index 1 as the pool start and index 2 as the length to range-check it over. So the out-of-bounds read is performed by the validation code itself, before the kernel service is reached, and the size the caller's pool start is then validated against is a word the manager has not proved the module owns. The other unproved word is read when the service's argument list is built.
Vulnerable function: `_txm_module_manager_tx_block_pool_create_dispatch`, in `common_modules/module_manager/inc/txm_module_manager_dispatch.h`.
