Title
wifi: mwifiex: fix use-after-free in mwifiex_adapter_cleanup()
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mwifiex: fix use-after-free in mwifiex_adapter_cleanup()
The mwifiex_adapter_cleanup() function uses timer_delete()
(non-synchronous) for the wakeup_timer before the adapter structure is
freed. This is incorrect because timer_delete() does not wait for any
running timer callback to complete.
If the wakeup_timer callback (wakeup_timer_fn) is executing when
mwifiex_adapter_cleanup() is called, the callback will continue to
access adapter fields (adapter->hw_status, adapter->if_ops.card_reset,
etc.) which may be freed by mwifiex_free_adapter() called later in the
mwifiex_remove_card() path.
Use timer_delete_sync() instead to ensure any running timer callback has
completed before returning.

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.
