Vulnerability from github – Published: 2026-07-19 18:31 – Updated: 2026-08-17 15:30

Details

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

drm/msm/adreno: Fix a reference leak in a6xx_gpu_init()

In a6xx_gpu_init(), node is obtained via of_parse_phandle(). While there was a manual of_node_put() at the end of the common path, several early error returns would bypass this call, resulting in a reference leak. Fix this by using the __free(device_node) cleanup handler to release the reference when the variable goes out of scope.

Severity

5.5 (Medium)

Detection rules are retrieved from Rulezet.

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.
