  "details": "In the Linux kernel, the following vulnerability has been resolved:  netfilter: nfnetlink_log: cope with concurrent instance destruction  Instances are refcounted. However, only memory release happens on the 1 -\u003e 0 transition; the unlink from hashes can occur with any refcount.  Uncooperative userspace can force a situation where a queue is pending for destruction from netlink event while a different socket with same portid processes an UNBIND request.  With right timing, this will unhash the instance again:  Oops: general protection fault, [..] Call Trace:  \u003cTASK\u003e  nfulnl_recv_config+0x31a/0xd50  nfnetlink_rcv_msg+0x7c2/0xeb0",
