"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: brcmsmac: fix UAF in brcms_free_timer()\n\nbrcms_free_timer() calls brcms_del_timer() which uses the non-synchronous\ncancel_delayed_work() to cancel the timer's underlying delayed work. 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."
