Vulnerability from github – Published: 2025-12-30 15:30 – Updated: 2025-12-30 15:30

Details

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

mmc: sunplus: fix return value check of mmc_add_host()

mmc_add_host() may return error, if we ignore its return value, 1. the memory allocated in mmc_alloc_host() will be leaked 2. null-ptr-deref will happen when calling mmc_remove_host() in remove function spmmc_drv_remove() because deleting not added device.

Fix this by checking the return value of mmc_add_host(). Moreover, I fixed the error handling path of spmmc_drv_probe() to clean up.

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.
