      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbatman-adv: tp_meter: fix tp_vars reference leak in receiver shutdown\n\nThe receiver shutdown timer handler, batadv_tp_receiver_shutdown(), is\nresponsible for releasing the tp_vars reference it holds. However, the\nexisting logic for coordinating this release with batadv_tp_stop_all() was\nflawed.\n\ntimer_shutdown_sync() guarantees the timer will not fire again after it\nreturns, but it returns non-zero only when the timer was pending at the\ntime of the call. If the timer had already expired (and\nbatadv_tp_stop_all() would unsucessfully try to  rearm itself),\nbatadv_tp_stop_all() skips its batadv_tp_vars_put(), and\nbatadv_tp_receiver_shutdown() fails to put its own reference as well.\n\nFix this by introducing a new atomic variable receiving that is set to 1\nwhen the receiver is initialized and cleared atomically with atomic_xchg()\nby whichever side claims it first. Only the side that observes the\ntransition from 1 to 0 is responsible for releasing the tp_vars timer\nreference, eliminating the uncertainty.",
