Details

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

gve: Implement gettimex64 with -EOPNOTSUPP

gve implemented a ptp_clock for sole use of do_aux_work at this time. ptp_clock_gettime() and ptp_sys_offset() assume every ptp_clock has implemented either gettimex64 or gettime64. Stub gettimex64 and return -EOPNOTSUPP to prevent NULL dereferencing.

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.
