CVE-2026-53147 (GCVE-0-2026-53147)
Vulnerability from cvelistv5
Published

Modified

Severity ?
8.1 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Validate XDomain request packet size before type cast tb_xdp_handle_request() casts the received packet buffer to protocol-specific structs without verifying that the allocation is large enough for the target type. A peer can send a minimal XDomain packet that passes the generic header length check but is shorter than the struct accessed after the cast, causing out-of- bounds reads from the kmemdup allocation. Plumb the packet length through xdomain_request_work and validate it against the expected struct size before each cast.

A malicious connected host, dock, or in-line device can send the malformed request packets.\nAC:L - The attacker controls the packet type, declared length, checksum, and payload size, and the generic header check accepts packets shorter than the later protocol-specific struct accesses. No race or condition outside attacker control is required once an XDomain peer is connected.\nPR:N - No target-system account or kernel capability is required; the packet is accepted from the external XDomain peer before any user credential check. XDomain must be enabled/allowed, but that is a platform configuration gate rather than attacker privilege.\nUI:N - After the malicious peer is connected, exploitation is driven entirely by packets sent over the Thunderbolt/USB4 control channel. No victim action such as opening a file or authorizing a user operation is required for the vulnerable parsing path.\nS:U - The impact is within the host kernel that processes the malformed XDomain packet. This is not a VM escape, IOMMU bypass, or cross-authority scope change.\nC:H - Short PROPERTIES_REQUEST packets cause reads past the kmemdup-allocated packet into adjacent kernel heap data, including UUID/offset fields used by the response logic. Under the required higher-severity rule for out-of-bounds reads, this is high confidentiality impact.\nI:N - The fixed bug is an out-of-bounds read before type-specific casts, not an out-of-bounds write or direct overwrite primitive. The affected paths may use the read value for response/link-state handling, but they do not provide attacker-controlled kernel memory modification.\nA:H - The malformed packet can drive kernel out-of-bounds heap reads from the control-channel workqueue and can be sent repeatedly by the peer. Such reads can fault or trigger kernel hardening/KASAN failures, so availability impact is high."

A malicious connected host, dock, or in-line device can send the malformed request packets.\\nAC:L - The attacker controls the packet type, declared length, checksum, and payload size, and the generic header check accepts packets shorter than the later protocol-specific struct accesses. No race or condition outside attacker control is required once an XDomain peer is connected.\\nPR:N - No target-system account or kernel capability is required; the packet is accepted from the external XDomain peer before any user credential check. XDomain must be enabled/allowed, but that is a platform configuration gate rather than attacker privilege.\\nUI:N - After the malicious peer is connected, exploitation is driven entirely by packets sent over the Thunderbolt/USB4 control channel. No victim action such as opening a file or authorizing a user operation is required for the vulnerable parsing path.\\nS:U - The impact is within the host kernel that processes the malformed XDomain packet. This is not a VM escape, IOMMU bypass, or cross-authority scope change.\\nC:H - Short PROPERTIES_REQUEST packets cause reads past the kmemdup-allocated packet into adjacent kernel heap data, including UUID/offset fields used by the response logic. Under the required higher-severity rule for out-of-bounds reads, this is high confidentiality impact.\\nI:N - The fixed bug is an out-of-bounds read before type-specific casts, not an out-of-bounds write or direct overwrite primitive. The affected paths may use the read value for response/link-state handling, but they do not provide attacker-controlled kernel memory modification.\\nA:H - The malformed packet can drive kernel out-of-bounds heap reads from the control-channel workqueue and can be sent repeatedly by the peer. Such reads can fault or trigger kernel hardening/KASAN failures, so availability impact is high.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"cdae7c07e3e3509eaabc18c1640a55dc5b99c179\", \"lessThan\": \"a770e62923090d7572f1f5a8507ae551d354a057\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"cdae7c07e3e3509eaabc18c1640a55dc5b99c179\", \"lessThan\": \"0dd61ba03d05187726ecdf9c0e2175a81b9b24f6\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"cdae7c07e3e3509eaabc18c1640a55dc5b99c179\", \"lessThan\": \"79235c8add5da4bf27a12f5a5dbb579f300c059e\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"cdae7c07e3e3509eaabc18c1640a55dc5b99c179\", \"lessThan\": \"46da5c3ea011e884028a91cf913db093920a915b\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"cdae7c07e3e3509eaabc18c1640a55dc5b99c179\", \"lessThan\": \"07cd2787cdf8942d24a1a3ef81aa89b526fb6381\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"cdae7c07e3e3509eaabc18c1640a55dc5b99c179\", \"lessThan\": \"a504b9f2797b739e0304d537e8aa4ce883ecce39\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/thunderbolt/xdomain.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"4.15\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"4.15\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.1.176\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.143\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.94\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.36\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.0.13\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.0.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/thunderbolt/xdomain.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/a770e62923090d7572f1f5a8507ae551d354a057\"}, {\"url\": \"https://git.kernel.org/stable/c/0dd61ba03d05187726ecdf9c0e2175a81b9b24f6\"}, {\"url\": \"https://git.kernel.org/stable/c/79235c8add5da4bf27a12f5a5dbb579f300c059e\"}, {\"url\": \"https://git.kernel.org/stable/c/46da5c3ea011e884028a91cf913db093920a915b\"}, {\"url\": \"https://git.kernel.org/stable/c/07cd2787cdf8942d24a1a3ef81aa89b526fb6381\"}, {\"url\": \"https://git.kernel.org/stable/c/a504b9f2797b739e0304d537e8aa4ce883ecce39\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nthunderbolt: Validate XDomain request packet size before type cast\\n\\ntb_xdp_handle_request() casts the received packet buffer to\\nprotocol-specific structs without verifying that the allocation\\nis large enough for the target type.
