  "description": "In the Linux kernel, the following vulnerability has been resolved:  nfsd: prevent panic for nfsv4.0 closed files in nfs4_show_open  Prior to commit 3f29cc82a84c (\u0022nfsd: split sc_status out of sc_type\u0022) states_show() relied on sc_type field to be of valid type before calling into a subfunction to show content of a particular stateid. From that commit, we split the validity of the stateid into sc_status and no longer changed sc_type to 0 while unhashing the stateid. This resulted in kernel oopsing for nfsv4.0 opens that stay around and in nfs4_show_open() would derefence sc_file which was NULL.  Instead, for closed open stateids forgo displaying information that relies of having a valid sc_file.  To reproduce: mount the server with 4.0, read and close a file and then on the server cat /proc/fs/nfsd/clients/2/states  [  513.590804] Call trace: [  513.590925]  _raw_spin_lock\u002B0xcc/0x160 [  513.591119]  nfs4_show_open\u002B0x78/0x2c0 [nfsd] [  513.591412]  states_show\u002B0x44c/0x488 [nfsd] [  513.591681]  seq_read_iter\u002B0x5d8/0x760 [  513.591896]  seq_read\u002B0x188/0x208 [  513.592075]  vfs_read\u002B0x148/0x470 [  513.592241]  ksys_read\u002B0xcc/0x178",
