CVE-2026-94202
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`.
