GHSA-6QQR-XMX9-C73W

Vulnerability from github – Published: 2026-09-11 21:31 – Updated: 2026-09-14 15:32

Details

In the Linux kernel, the following vulnerability has been resolved:

tpm: tpm_i2c_nuvoton: disable IRQ on wait timeout

i2c_nuvoton_wait_for_stat() enables the IRQ before waiting for the interrupt handler to report a status change. If the wait times out, or is interrupted before the handler runs, the function returns without balancing the enable_irq() call.

Disable the IRQ before leaving the failed wait path. Also preserve an interrupted wait's original error code instead of converting it to -ETIMEDOUT inside the helper.

Detection rules are retrieved from Rulezet.

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.
