  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nrxrpc: Fix call removal to use RCU safe deletion\n\nFix rxrpc call removal from the rxnet-\u003ecalls list to use list_del_rcu()\nrather than list_del_init() to prevent stuffing up reading\n/proc/net/rxrpc/calls from potentially getting into an infinite loop.\n\nThis, however, means that list_empty() no longer works on an entry that's\nbeen deleted from the list, making it harder to detect prior deletion.  Fix\nthis by:\n\nFirstly, make rxrpc_destroy_all_calls() only dump the first ten calls that\nare unexpectedly still on the list.  Limiting the number of steps means\nthere's no need to call cond_resched() or to remove calls from the list\nhere, thereby eliminating the need for rxrpc_put_call() to check for that.\n\nrxrpc_put_call() can then be fixed to unconditionally delete the call from\nthe list as it is the only place that the deletion occurs.",
