A short AUTH_RECEIVE buffer can pass the\ncheck before the challenge is copied past the end of its allocation.\n\nUse the typed challenge pointer when calculating the response size.\n\n  BUG: KASAN: slab-out-of-bounds in nvmet_execute_auth_receive (drivers/nvme/target/fabrics-cmd-auth.c:442 drivers/nvme/target/fabrics-cmd-auth.c:569)\n  Write of size 32 by task kworker/1:1H/64\n  Workqueue: nvmet_tcp_wq nvmet_tcp_io_work\n  Call Trace:\n  nvmet_execute_auth_receive (drivers/nvme/target/fabrics-cmd-auth.c:442 drivers/nvme/target/fabrics-cmd-auth.c:569)\n  nvmet_tcp_try_recv_pdu (drivers/nvme/target/tcp.c:1119 drivers/nvme/target/tcp.c:1243)\n  nvmet_tcp_io_work (drivers/nvme/target/tcp.c:1350 drivers/nvme/target/tcp.c:1382 drivers/nvme/target/tcp.c:1445)\n  process_one_work (kernel/workqueue.c:3322)\n  worker_thread (kernel/workqueue.c:3405 kernel/workqueue.c:3486)\n  kthread (kernel/kthread.c:436)\n  ret_from_fork (arch/x86/kernel/process.c:158)\n  ret_from_fork_asm (arch/x86/entry/entry_64.S:245)\n  The buggy address is located 16 bytes inside of\n   allocated 33-byte region [ffff888000554e80, ffff888000554ea1)\n  Kernel panic - not syncing: KASAN: panic_on_warn set ...",
