Title
thunderbolt: Limit XDomain response copy to actual frame size
Summary
In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Limit XDomain response copy to actual frame size tb_xdomain_copy() copies req->response_size bytes from the received packet buffer regardless of the actual frame size. When a short response arrives, this reads past the valid frame data in the DMA pool buffer into stale contents from previous transactions. Use the minimum of frame size and expected response size for the copy length.

No race or external timing condition is required.\nPR:N - The attacker is the external XDomain peer and does not need credentials or privileges on the victim Linux system. The module parameter and ACPI allowance are deployment gates, not attacker privilege checks.\nUI:N - After the malicious peer is present on the Thunderbolt/USB4 link, XDomain discovery runs automatically. No victim user action is required to trigger the vulnerable copy.\nS:U - The vulnerable code and impacts are within the victim kernel/Thunderbolt domain. This does not cross a VM, IOMMU, or separate security authority boundary.\nC:H - The bug is an out-of-bounds source read from the Thunderbolt control DMA frame buffer into kernel response objects, exposing stale contents from previous transactions. Because the over-read is not limited to only a few bytes and can influence/reflection paths such as XDomain UUID/properties handling, confidentiality is High.\nI:L - Stale bytes copied into trusted XDomain response structures can alter limited kernel protocol state such as peer identity, route, link status, or advertised properties. There is no direct arbitrary write or control-flow corruption from this fix alone.\nA:N - The copy destination is sized for the expected response, and the over-read stays within the DMA frame allocation rather than causing an immediate kernel crash. A malicious peer can disrupt its own XDomain handshake, but this bug does not create a distinct system availability impact."

No race or external timing condition is required.\nPR:N - The attacker is the external XDomain peer and does not need credentials or privileges on the victim Linux system. The module parameter and ACPI allowance are deployment gates, not attacker privilege checks.\nUI:N - After the malicious peer is present on the Thunderbolt/USB4 link, XDomain discovery runs automatically. No victim user action is required to trigger the vulnerable copy.\nS:U - The vulnerable code and impacts are within the victim kernel/Thunderbolt domain. This does not cross a VM, IOMMU, or separate security authority boundary.\nC:H - The bug is an out-of-bounds source read from the Thunderbolt control DMA frame buffer into kernel response objects, exposing stale contents from previous transactions. Because the over-read is not limited to only a few bytes and can influence/reflection paths such as XDomain UUID/properties handling, confidentiality is High.\nI:L - Stale bytes copied into trusted XDomain response structures can alter limited kernel protocol state such as peer identity, route, link status, or advertised properties. There is no direct arbitrary write or control-flow corruption from this fix alone.\nA:N - The copy destination is sized for the expected response, and the over-read stays within the DMA frame allocation rather than causing an immediate kernel crash.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
