Details

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

staging: media: atomisp: Disallow all private IOCTLs

Disallow all private IOCTLs. These aren't quite as safe as one could assume of IOCTL handlers; disable them for now. Instead of removing the code, return in the beginning of the function if cmd is non-zero in order to keep static checkers happy.

Severity

7.8 (High)

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.
