Title
ksmbd: fix potencial out-of-bounds when buffer offset is invalid
Summary
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix potencial out-of-bounds when buffer offset is invalid I found potencial out-of-bounds when buffer offset fields of a few requests is invalid. This patch set the minimum value of buffer offset field to ->Buffer offset to validate buffer length.

              "value": "AV:N - ksmbd is the in-kernel SMB server listening on TCP/445; the malformed offset fields are attacker-supplied bytes in an SMB2 PDU sent over the network. No local access is needed.\nAC:L - The attacker simply sets a buffer-offset field (PathOffset, InputBufferOffset, BufferOffset, FileNameOffset, InputOffset) below the struct\u0027s Buffer offset in a single crafted request; the divergence between the validated window and the read window is deterministic, with no race or unknown state involved.\nPR:L - All affected commands pass through smb2_check_user_session(), which requires ksmbd_conn_good() and a valid session, so a completed SMB2 session setup (any low-privileged share user, or a mapped guest) is needed; the remaining commands additionally need a tree connect. This matches the sibling fix CVE-2024-26954.\nUI:N - The server processes the crafted SMB2 request automatically in its kworker; no action by any local user or administrator is required.\nS:U - The out-of-bounds access and its consequences stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is an out-of-bounds read of adjacent kernel heap memory of up to the fixed-header size (~120 bytes) per request, repeatable with attacker-controlled heap grooming, and the leaked bytes are reflected back to the client through FSCTL_PIPE_TRANSCEIVE responses, tree-connect/query-directory name handling and EA replies, yielding kernel memory disclosure.\nI:L - SMB2_SET_INFO and FSCTL handlers consume the out-of-bounds bytes as file metadata \u2014 FILE_END_OF_FILE_INFORMATION truncation lengths, rename/link names, extended attributes, security descriptors and FSCTL_SET_ZERO_DATA ranges \u2014 so file data and permissions are modified, but the attacker does not fully control the resulting values.\nA:H - Reading past the kvmalloc()\u0027d request buffer triggers a KASAN slab-out-of-bounds BUG or a fault on a vmalloc guard page, oopsing the ksmbd kworker and killing the server; the attacker can repeat it at will from the network."

No local access is needed.\\nAC:L - The attacker simply sets a buffer-offset field (PathOffset, InputBufferOffset, BufferOffset, FileNameOffset, InputOffset) below the struct\u0027s Buffer offset in a single crafted request; the divergence between the validated window and the read window is deterministic, with no race or unknown state involved.\\nPR:L - All affected commands pass through smb2_check_user_session(), which requires ksmbd_conn_good() and a valid session, so a completed SMB2 session setup (any low-privileged share user, or a mapped guest) is needed; the remaining commands additionally need a tree connect. This matches the sibling fix CVE-2024-26954.\\nUI:N - The server processes the crafted SMB2 request automatically in its kworker; no action by any local user or administrator is required.\\nS:U - The out-of-bounds access and its consequences stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\\nC:H - This is an out-of-bounds read of adjacent kernel heap memory of up to the fixed-header size (~120 bytes) per request, repeatable with attacker-controlled heap grooming, and the leaked bytes are reflected back to the client through FSCTL_PIPE_TRANSCEIVE responses, tree-connect/query-directory name handling and EA replies, yielding kernel memory disclosure.\\nI:L - SMB2_SET_INFO and FSCTL handlers consume the out-of-bounds bytes as file metadata \\u2014 FILE_END_OF_FILE_INFORMATION truncation lengths, rename/link names, extended attributes, security descriptors and FSCTL_SET_ZERO_DATA ranges \\u2014 so file data and permissions are modified, but the attacker does not fully control the resulting values.\\nA:H - Reading past the kvmalloc()\u0027d request buffer triggers a KASAN slab-out-of-bounds BUG or a fault on a vmalloc guard page, oopsing the ksmbd kworker and killing the server; the attacker can repeat it at will from the network.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"0626e6641f6b467447c81dd7678a69c66f7746cf\", \"lessThan\": \"480469f145e5abf83361e608734e421b7d99693d\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0626e6641f6b467447c81dd7678a69c66f7746cf\", \"lessThan\": \"ad6480c9a5d884e2704adc51d69895d93339176c\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0626e6641f6b467447c81dd7678a69c66f7746cf\", \"lessThan\": \"39bdc4197acf2ed13269167ccf093ee28cfa2a4e\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0626e6641f6b467447c81dd7678a69c66f7746cf\", \"lessThan\": \"2dcda336b6e80b72d58d30d40f2fad9724e5fe63\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0626e6641f6b467447c81dd7678a69c66f7746cf\", \"lessThan\": \"0c5541b4c980626fa3cab16ba1a451757778bbb5\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0626e6641f6b467447c81dd7678a69c66f7746cf\", \"lessThan\": \"c6cd2e8d2d9aa7ee35b1fa6a668e32a22a9753da\", \"versionType\": \"git\"}], \"programFiles\": [\"fs/smb/server/smb2misc.c\", \"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\": \"5.15.181\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.119\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.32\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.7.12\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.7.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8.3\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.8.*\"}, {\"status\": \"unaffected\", \"version\": \"6.9\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"fs/smb/server/smb2misc.c\", \"fs/smb/server/smb2pdu.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/480469f145e5abf83361e608734e421b7d99693d\"}, {\"url\": \"https://git.kernel.org/stable/c/ad6480c9a5d884e2704adc51d69895d93339176c\"}, {\"url\": \"https://git.kernel.org/stable/c/39bdc4197acf2ed13269167ccf093ee28cfa2a4e\"}, {\"url\": \"https://git.kernel.org/stable/c/2dcda336b6e80b72d58d30d40f2fad9724e5fe63\"}, {\"url\": \"https://git.kernel.org/stable/c/0c5541b4c980626fa3cab16ba1a451757778bbb5\"}, {\"url\": \"https://git.kernel.org/stable/c/c6cd2e8d2d9aa7ee35b1fa6a668e32a22a9753da\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nksmbd: fix potencial out-of-bounds when buffer offset is invalid\\n\\nI found potencial out-of-bounds when buffer offset fields of a few requests\\nis invalid.
