Details

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

fs/ntfs3: Add null pointer check for inode operations

This adds a sanity check for the i_op pointer of the inode which is returned after reading Root directory MFT record. We should check the i_op is valid before trying to create the root dentry, otherwise we may encounter a NPD while mounting a image with a funny Root directory MFT record.

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Add null pointer check for inode operations This adds a sanity check for the i_op pointer of the inode which is returned after reading Root directory MFT record. We should check the i_op is valid before trying to create the root dentry, otherwise we may encounter a NPD while mounting a image with a funny Root directory MFT record.

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.
