Details
In the Linux kernel, the following vulnerability has been resolved:
serial: 8250: omap: Don't skip resource freeing if pm_runtime_resume_and_get() failed
Returning an error code from .remove() makes the driver core emit the little helpful error message:
remove callback returned a non-zero value. This will be ignored.
and then remove the device anyhow. So all resources that were not freed are leaked in this case. Skipping serial8250_unregister_port() has the potential to keep enough of the UART around to trigger a use-after-free.
So replace the error return (and with it the little helpful error message) by a more useful error message and continue to cleanup.
Severity
7.8 (High)

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.
