      "title": "net: use sock_gen_put() when sk_state is TCP_TIME_WAIT",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: use sock_gen_put() when sk_state is TCP_TIME_WAIT\n\nIt is possible for a pointer of type struct inet_timewait_sock to be\nreturned from the functions __inet_lookup_established() and\n__inet6_lookup_established(). This can cause a crash when the\nreturned pointer is of type struct inet_timewait_sock and\nsock_put() is called on it. The following is a crash call stack that\nshows sk->sk_wmem_alloc being accessed in sk_free() during the call to\nsock_put() on a struct inet_timewait_sock pointer. To avoid this issue,\nuse sock_gen_put() instead of sock_put() when sk->sk_state\nis TCP_TIME_WAIT.\n\nmrdump.ko        ipanic() + 120\nvmlinux          notifier_call_chain(nr_to_call=-1, nr_calls=0) + 132\nvmlinux          atomic_notifier_call_chain(val=0) + 56\nvmlinux          panic() + 344\nvmlinux          add_taint() + 164\nvmlinux          end_report() + 136\nvmlinux          kasan_report(size=0) + 236\nvmlinux          report_tag_fault() + 16\nvmlinux          do_tag_recovery() + 16\nvmlinux          __do_kernel_fault() + 88\nvmlinux          do_bad_area() + 28\nvmlinux          do_tag_check_fault() + 60\nvmlinux          do_mem_abort() + 80\nvmlinux          el1_abort() + 56\nvmlinux          el1h_64_sync_handler() + 124\nvmlinux        > 0xFFFFFFC080011294()\nvmlinux          __lse_atomic_fetch_add_release(v=0xF2FFFF82A896087C)\nvmlinux          __lse_atomic_fetch_sub_release(v=0xF2FFFF82A896087C)\nvmlinux          arch_atomic_fetch_sub_release(i=1, v=0xF2FFFF82A896087C)\n+ 8\nvmlinux          raw_atomic_fetch_sub_release(i=1, v=0xF2FFFF82A896087C)\n+ 8\nvmlinux          atomic_fetch_sub_release(i=1, v=0xF2FFFF82A896087C) + 8\nvmlinux          __refcount_sub_and_test(i=1, r=0xF2FFFF82A896087C,\noldp=0) + 8\nvmlinux          __refcount_dec_and_test(r=0xF2FFFF82A896087C, oldp=0) + 8\nvmlinux          refcount_dec_and_test(r=0xF2FFFF82A896087C) + 8\nvmlinux          sk_free(sk=0xF2FFFF82A8960700) + 28\nvmlinux          sock_put() + 48\nvmlinux          tcp6_check_fraglist_gro() + 236\nvmlinux          tcp6_gro_receive() + 624\nvmlinux          ipv6_gro_receive() + 912\nvmlinux          dev_gro_receive() + 1116\nvmlinux          napi_gro_receive() + 196\nccmni.ko         ccmni_rx_callback() + 208\nccmni.ko         ccmni_queue_recv_skb() + 388\nccci_dpmaif.ko   dpmaif_rxq_push_thread() + 1088\nvmlinux          kthread() + 268\nvmlinux          0xFFFFFFC08001F30C()",
