## Description

In the Linux kernel, the following vulnerability has been resolved:  smb: client: fix double free of TCP_Server_Info::hostname  When shutting down the server in cifs_put_tcp_session(), cifsd thread might be reconnecting to multiple DFS targets before it realizes it should exit the loop, so @server->hostname can't be freed as long as cifsd thread isn't done.  Otherwise the following can happen:    RIP: 0010:__slab_free+0x223/0x3c0   Code: 5e 41 5f c3 cc cc cc cc 4c 89 de 4c 89 cf 44 89 44 24 08 4c 89   1c 24 e8 fb cf 8e 00 44 8b 44 24 08 4c 8b 1c 24 e9 5f fe ff ff <0f>   0b 41 f7 45 08 00 0d 21 00 0f 85 2d ff ff ff e9 1f ff ff ff 80   RSP: 0018:ffffb26180dbfd08 EFLAGS: 00010246   RAX: ffff8ea34728e510 RBX: ffff8ea34728e500 RCX: 0000000000800068   RDX: 0000000000800068 RSI: 0000000000000000 RDI: ffff8ea340042400   RBP: ffffe112041ca380 R08: 0000000000000001 R09: 0000000000000000   R10: 6170732e31303000 R11: 70726f632e786563 R12: ffff8ea34728e500   R13: ffff8ea340042400 R14: ffff8ea34728e500 R15: 0000000000800068   FS: 0000000000000000(0000) GS:ffff8ea66fd80000(0000)   000000   CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033   CR2: 00007ffc25376080 CR3: 000000012a2ba001 CR4:   PKRU: 55555554   Call Trace:    <TASK>    ? show_trace_log_lvl+0x1c4/0x2df    ? show_trace_log_lvl+0x1c4/0x2df    ? __reconnect_target_unlocked+0x3e/0x160 [cifs]    ? __die_body.cold+0x8/0xd    ? die+0x2b/0x50    ? do_trap+0xce/0x120    ? __slab_free+0x223/0x3c0    ? do_error_trap+0x65/0x80    ? __slab_free+0x223/0x3c0    ? exc_invalid_op+0x4e/0x70    ? __slab_free+0x223/0x3c0    ? asm_exc_invalid_op+0x16/0x20    ? __slab_free+0x223/0x3c0    ? extract_hostname+0x5c/0xa0 [cifs]    ? extract_hostname+0x5c/0xa0 [cifs]    ? __kmalloc+0x4b/0x140    __reconnect_target_unlocked+0x3e/0x160 [cifs]    reconnect_dfs_server+0x145/0x430 [cifs]    cifs_handle_standard+0x1ad/0x1d0 [cifs]    cifs_demultiplex_thread+0x592/0x730 [cifs]    ? __pfx_cifs_demultiplex_thread+0x10/0x10 [cifs]    kthread+0xdd/0x100    ? __pfx_kthread+0x10/0x10    ret_from_fork+0x29/0x50    </TASK>
