If\nthe work callback (_brcms_timer) is already running, cancel_delayed_work()\nreturns false without waiting, and brcms_free_timer() proceeds to kfree(t)\nwhile the callback still accesses t through container_of().\n\nAdd an explicit cancel_delayed_work_sync() after brcms_del_timer() to\nguarantee that any in-flight callback has completed before the timer\nstructure is freed.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
