CVE-2026-102710

Attacker model / Preconditions: a loaded TXMMODULEUSERMODE | TXMMODULEMEMORYPROTECTION module issuing kernel dispatch calls, on a build with TXENABLEEVENT_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.
