  "details": "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-\u003ecoredump.crash_data) | mt7996_mac_dump_work()                                    |  crash_data-\u003e // 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.",
