Title
drm/connector: hdmi: Fix memory leak in drm_display_mode_from_cea_vic()
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/connector: hdmi: Fix memory leak in drm_display_mode_from_cea_vic()
modprobe drm_connector_test and then rmmod drm_connector_test,
the following memory leak occurs.
The `mode` allocated in drm_mode_duplicate() called by
drm_display_mode_from_cea_vic() is not freed, which cause the memory leak:
unreferenced object 0xffffff80cb0ee400 (size 128):

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.
