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."

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.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"0626e6641f6b467447c81dd7678a69c66f7746cf\", \"lessThan\": \"c7ab587bd33ce45e2aa6b6d2d36be7ef0bd16614\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0626e6641f6b467447c81dd7678a69c66f7746cf\", \"lessThan\": \"1d7ee876b8b96efc14e177a7fe8d45ac25d68849\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0626e6641f6b467447c81dd7678a69c66f7746cf\", \"lessThan\": \"52cefcff6a4a814f4f8e357422fcfb71fd2ebf75\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0626e6641f6b467447c81dd7678a69c66f7746cf\", \"lessThan\": \"21e46a79bbe6c4e1aa73b3ed998130f2ff07b128\", \"versionType\": \"git\"}], \"programFiles\": [\"fs/smb/server/smb2pdu.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.15\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.15\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.1.164\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.70\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.9\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.13\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"fs/smb/server/smb2pdu.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/c7ab587bd33ce45e2aa6b6d2d36be7ef0bd16614\"}, {\"url\": \"https://git.kernel.org/stable/c/1d7ee876b8b96efc14e177a7fe8d45ac25d68849\"}, {\"url\": \"https://git.kernel.org/stable/c/52cefcff6a4a814f4f8e357422fcfb71fd2ebf75\"}, {\"url\": \"https://git.kernel.org/stable/c/21e46a79bbe6c4e1aa73b3ed998130f2ff07b128\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nksmbd: set ATTR_CTIME flags when setting mtime\\n\\nDavid reported that the new warning from setattr_copy_mgtime is coming\\nlike the following.\\n\\n[  113.215316] ------------[ cut here ]------------\\n[  113.215974] WARNING: CPU: 1 PID: 31 at fs/attr.c:300 setattr_copy+0x1ee/0x200\\n[  113.219192] CPU: 1 UID: 0 PID: 31 Comm: kworker/1:1 Not tainted 6.13.0-rc1+ #234\\n[  113.220127] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.2-3-gd478f380-rebuilt.opensuse.org 04/01/2014\\n[  113.221530] Workqueue: ksmbd-io handle_ksmbd_work [ksmbd]\\n[  113.222220] RIP: 0010:setattr_copy+0x1ee/0x200\\n[  113.222833] Code: 24 28 49 8b 44 24 30 48 89 53 58 89 43 6c 5b 41 5c 41 5d 41 5e 41 5f 5d c3 cc cc cc cc 48 89 df e8 77 d6 ff ff e9 cd fe ff ff \u003c0f\u003e 0b e9 be fe ff ff 66 0\\n[  113.225110] RSP: 0018:ffffaf218010fb68 EFLAGS: 00010202\\n[  113.225765] RAX: 0000000000000120 RBX: ffffa446815f8568 RCX: 0000000000000003\\n[  113.226667] RDX: ffffaf218010fd38 RSI: ffffa446815f8568 RDI: ffffffff94eb03a0\\n[  113.227531] RBP: ffffaf218010fb90 R08: 0000001a251e217d R09: 00000000675259fa\\n[  113.228426] R10: 0000000002ba8a6d R11: ffffa4468196c7a8 R12: ffffaf218010fd38\\n[  113.229304] R13: 0000000000000120 R14: ffffffff94eb03a0 R15: 0000000000000000\\n[  113.230210] FS:  0000000000000000(0000) GS:ffffa44739d00000(0000) knlGS:0000000000000000\\n[  113.231215] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\\n[  113.232055] CR2: 00007efe0053d27e CR3: 000000000331a000 CR4: 00000000000006b0\\n[  113.232926] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\\n[  113.233812] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\\n[  113.234797] Call Trace:\\n[  113.235116]  \u003cTASK\u003e\\n[  113.235393]  ?
