Title
slimbus: core: fix device reference leak on report present
Summary
In the Linux kernel, the following vulnerability has been resolved:
slimbus: core: fix device reference leak on report present
Slimbus devices can be allocated dynamically upon reception of
report-present messages.
Make sure to drop the reference taken when looking up already registered
devices.
Note that this requires taking an extra reference in case the device has
not yet been registered and has to be allocated.

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.
