Vulnerability from github – Published: 2026-09-29 18:31 – Updated: 2026-09-29 18:32

Details

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.

Severity

9.3 (Critical)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
