Title
nfs/blocklayout: Don't attempt unregister for invalid block device
Summary
In the Linux kernel, the following vulnerability has been resolved: nfs/blocklayout: Don't attempt unregister for invalid block device Since commit d869da91cccb ("nfs/blocklayout: Fix premature PR key unregistration") an unmount of a pNFS SCSI layout-enabled NFS may dereference a NULL block_device in: bl_unregister_scsi+0x16/0xe0 [blocklayoutdriver] bl_free_device+0x70/0x80 [blocklayoutdriver] bl_free_deviceid_node+0x12/0x30 [blocklayoutdriver] nfs4_put_deviceid_node+0x60/0xc0 [nfsv4] nfs4_deviceid_purge_client+0x132/0x190 [nfsv4] unset_pnfs_layoutdriver+0x59/0x60 [nfsv4] nfs4_destroy_server+0x36/0x70 [nfsv4] nfs_free_server+0x23/0xe0 [nfs] deactivate_locked_super+0x30/0xb0 cleanup_mnt+0xba/0x150 task_work_run+0x59/0x90 syscall_exit_to_user_mode+0x217/0x220 do_syscall_64+0x8e/0x160 This happens because even though we were able to create the nfs4_deviceid_node, the lookup for the device was unable to attach the block device to the pnfs_block_dev. If we never found a block device to register, we can avoid this case with the PNFS_BDEV_REGISTERED flag. Move the deref behind the test for the flag.

No local access to the victim client is needed.\nAC:L - The server fully controls the SCSI designator, and any well-formed NAA/EUI64 designator not matching a local `/dev/disk/by-id/` entry deterministically leaves `bdev_file` NULL; LAYOUT_SCSI is the client\u0027s highest-preference layout type and `blocklayoutdriver` autoloads, so no special victim configuration or timing is required.\nPR:N - The attacker acts as the NFS server (or a MITM/compromised trusted server) and holds no credentials or account on the victim client; the client itself initiates the exchange and consumes the reply with no authorization check on the device description.\nUI:N - On an already-established pNFS-capable NFSv4.1 mount \u2014 the normal state in enterprise/SAN deployments \u2014 a malicious or compromised server can hand out the bad SCSI deviceid and then revoke recallable state to force the purge with no action by any user.\nS:U - The NULL dereference occurs in kernel context within the NFS client and its impact is confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - The dereference is at a fixed low offset from NULL (`f_mapping` at ~0x18 in `struct file`), which is unmapped under `mmap_min_addr`; no memory contents are read out or disclosed to the attacker.\nI:N - The bug provides only a read of an unmapped low address, yielding no write primitive or control over kernel data; no memory is modified before the fault.\nA:H - The oops kills the faulting task \u2014 either `umount` (leaving the NFS superblock permanently wedged) or the NFS state-manager kernel thread (hanging all NFS I/O for that client) \u2014 and on the many deployments running `panic_on_oops` it is a full system panic, repeatable at the attacker\u0027s will."
