Vulnerability from github – Published: 2026-10-28 12:31 – Updated: 2026-10-28 12:31

Details

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

i2c: viai2c-wmt: Fix clock leak in wmt_i2c_probe()

In wmt_i2c_probe(), i2c->clk is acquired using of_clk_get(). If any subsequent operation fails or when the module is unloaded, the clock reference count is never decremented via clk_put(), leading to a resource leak.

Switch to devm_clk_get() so that the clock is automatically managed and released.

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.
