staging: rtl8192e: Fix use after free in _rtl92e_pci_disconnect()
Summary
In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8192e: Fix use after free in _rtl92e_pci_disconnect()
The free_rtllib() function frees the "dev" pointer so there is use
after free on the next line. Re-arrange things to avoid that.

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.
