Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix memory leak in ocfs2_stack_glue_init()
ocfs2_table_header should be free in ocfs2_stack_glue_init() if
ocfs2_sysfs_init() failed, otherwise kmemleak will report memleak.

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.
