wifi: mt76: mt7996: fix use-after-free bugs in mt7996_mac_dump_work()
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: fix use-after-free bugs in mt7996_mac_dump_work() When the mt7996 pci chip is detaching, the mt7996_crash_data is released in mt7996_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 mt7996_mac_dump_work(). The race condition can occur as follows: CPU 0 (removal path) | CPU 1 (workqueue) mt7996_pci_remove() | mt7996_sys_recovery_set() mt7996_unregister_device() | mt7996_reset() mt7996_coredump_unregister() | queue_work() vfree(dev->coredump.crash_data) | mt7996_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 mt7996_unregister_device() to synchronize with any pending or executing dump work.
