Title
wifi: mt76: mt7915: fix use-after-free bugs in mt7915_mac_dump_work()
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: fix use-after-free bugs in mt7915_mac_dump_work()
When the mt7915 pci chip is detaching, the mt7915_crash_data is
released in mt7915_coredump_unregister(). However, the work item
dump_work may still be running or pending, leading to UAF bugs
when the already freed crash_data is dereferenced again in
mt7915_mac_dump_work().
The race condition can occur as follows:
CPU 0 (removal path) | CPU 1 (workqueue)
mt7915_pci_remove() | mt7915_sys_recovery_set()
mt7915_unregister_device() | mt7915_reset()
mt7915_coredump_unregister() | queue_work()
vfree(dev->coredump.crash_data) | mt7915_mac_dump_work()
| crash_data-> // UAF
Fix this by ensuring dump_work is properly canceled before
the crash_data is deallocated. Add cancel_work_sync() in
mt7915_unregister_device() to synchronize with any pending
or executing dump work.

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.
