No local access to the target is needed.\nAC:L - Any SMB2_SET_INFO with a non-zero LastWriteTime deterministically strips ATTR_CTIME while leaving ATTR_MTIME set, hitting the WARN on the first attempt \u2014 this is what an ordinary `touch -m` or file copy over the share does. The only precondition is an mgtime filesystem, which is the default for btrfs, ext4 and xfs, i.e. essentially all ksmbd exports.\nPR:L - The command is dispatched only after `check_user_session()` and `get_ksmbd_tcon()` succeed, and `smb2_set_info()` additionally requires a writable tree connect plus a handle opened with FILE_WRITE_ATTRIBUTES, so the attacker needs an established SMB session. Any ordinary share user \u2014 including a mapped guest account on the many NAS/embedded deployments that enable one \u2014 qualifies; no administrative rights are involved.\nUI:N - The attacker performs every step itself \u2014 connect, session setup, tree connect, SMB2_CREATE, SMB2_SET_INFO. No action by a local user or administrator is required.\nS:U - The warning and the resulting panic are confined to the kernel of the machine running ksmbd; no VM, container, or IOMMU boundary is crossed and no other security authority is affected.\nC:N - There is no out-of-bounds or uninitialized read \u2014 `attrs.ia_ctime` is always initialized before use and the bug is a pure flag-consistency assertion. The WARN splat goes only to the kernel log, which the remote SMB client cannot read, and nothing extra is returned in the SMB response.\nI:L - With ATTR_CTIME stripped, `setattr_copy_mgtime()` takes the else branch and leaves ctime untouched while applying the attacker\u0027s ATTR_MTIME_SET value, so a client can rewrite a file\u0027s mtime without ctime advancing \u2014 defeating the ctime-based change detection that backup, NFS re-export cache coherency, and file-integrity monitors rely on. The effect is bounded to inode timestamp metadata; there is no arbitrary write or control-flow primitive.\nA:H - The bug triggers `WARN_ON_ONCE()` at fs/attr.c:300 in the ksmbd-io workqueue context, which under the widely deployed `panic_on_warn=1` setting (hardened cloud, Android, embedded and automotive images) turns the first request into an immediate kernel panic and full loss of the file server. Even without panic_on_warn it is an unconditional kernel oops-class splat driven by a remote peer."
