CVE-2026-102710
Azure RTOS ThreadX Kernel Privilege Escalation via Improper Callback Validation
Description

Attacker model / Preconditions: a loaded `TXM_MODULE_USER_MODE | TXM_MODULE_MEMORY_PROTECTION` module issuing kernel dispatch calls, on a build with `TX_ENABLE_EVENT_TRACE`. A user-mode, memory-protected module can register an arbitrary function pointer as the global trace-full callback. The kernel calls it directly — no validation, no trampoline — from privileged kernel code when the trace buffer wraps. An invalid pointer faults the kernel (DoS). A pointer into the module's own code was observed running with kernel privilege (`CONTROL.nPRIV = 0`), confirmed at runtime with a register capture inside that code.
