VLAI
Details
In the Linux kernel, the following vulnerability has been resolved:
drm/radeon: Add the missed acpi_put_table() to fix memory leak
When the radeon driver reads the bios information from ACPI table in radeon_acpi_vfct_bios(), it misses to call acpi_put_table() to release the ACPI memory after the init, so add acpi_put_table() properly to fix the memory leak.
v2: fix text formatting (Alex)
Severity
5.5 (Medium)

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.
