Details
In the Linux kernel, the following vulnerability has been resolved:
i2c: mlxbf: Fix use-after-free in mlxbf_i2c_init_resource()
If devm_platform_get_and_ioremap_resource() returns an error, mlxbf_i2c_init_resource() frees tmp_res before reading tmp_res->io to get the error code. This results in a use-after-free.
Save the error code before freeing tmp_res.

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.
