  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7996: fix use-after-free bugs in mt7996_mac_dump_work()\n\nWhen the mt7996 pci chip is detaching, the mt7996_crash_data is\nreleased in mt7996_coredump_unregister(). However, the work item\ndump_work may still be running or pending, leading to UAF bugs\nwhen the already freed crash_data is dereferenced again in\nmt7996_mac_dump_work().\n\nThe race condition can occur as follows:\n\nCPU 0 (removal path)               | CPU 1 (workqueue)\nmt7996_pci_remove()                | mt7996_sys_recovery_set()\n mt7996_unregister_device()        |  mt7996_reset()\n  mt7996_coredump_unregister()     |   queue_work()\n   vfree(dev-\u003ecoredump.crash_data) | mt7996_mac_dump_work()\n                                   |  crash_data-\u003e // UAF\n\nFix this by ensuring dump_work is properly canceled before\nthe crash_data is deallocated. Add cancel_work_sync() in\nmt7996_unregister_device() to synchronize with any pending\nor executing dump work.",
