GSD-2020-36778
Vulnerability from gsd - Updated: 2024-02-27 06:02Details
In the Linux kernel, the following vulnerability has been resolved:
i2c: xiic: fix reference leak when pm_runtime_get_sync fails
The PM reference count is not expected to be incremented on
return in xiic_xfer and xiic_i2c_remove.
However, pm_runtime_get_sync will increment the PM reference
count even failed. Forgetting to putting operation will result
in a reference leak here.
Replace it with pm_runtime_resume_and_get to keep usage
counter balanced.

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.
