I am seeing xHCI errors “Transfer event TRB DMA ptr not part of current TD” on Jetson Orin NX. I noticed that upstream Linux has a patch related to this issue (CVE-2025-22022), and I would like to confirm whether the current Jetson Linux kernel already includes this patch. If not, I would like to know how to correctly integrate it into the Jetson kernel. Current system and kernel information My environment is: Hardware: Jetson Orin NX Developer Kit Jetson Linux / L4T version (from /etc/nv_tegra_release): R36 (release), REVISION: 4.7, GCID: 42132812, BOARD: generic, EABI: aarch64, DATE: Thu Sep 18 22:54:44 UTC 2025 KERNEL_VARIANT: oot Kernel version (uname -a): Linux jetson 5.15.148-tegra #1 SMP PREEMPT Mon Jun 16 08:24:48 PDT 2025 aarch64 aarch64 aarch64 GNU/Linux Kernel package version (dpkg -l | grep nvidia-l4t-kernel): ii nvidia-l4t-kernel 5.15.148-tegra-36.4.4-20250616085344 arm64 NVIDIA Kernel Package ii nvidia-l4t-kernel-dtbs 5.15.148-tegra-36.4.4-20250616085344 arm64 NVIDIA Kernel DTB Package … So the overall L4T release is reported as R36.4.7, but the actual kernel package in use is 36.4.4. xHCI errors and relation to CVE-2025-22022 In USB3 UVC camera scenarios with multiple different xHCI controllers, including: The Jetson Orin NX SoC’s on-board xHCI controller, An external ASMedia ASM2142 PCIe–USB3 controller, And a NEC uPD720200 series controller used for testing, I repeatedly see similar error messages in dmesg. For example: xhci_hcd 0007:01:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 2 comp_code 13 xhci_hcd 0007:01:00.0: Looking for event-dma 00000000fffd11c0 trb-start 00000000fffd1180 trb-end 00000000fffd1180 seg-start 00000000fffd1000 seg-end 00000000fffd1ff0 In other words, I observe this “Transfer event TRB DMA ptr not part of current TD” error pattern on different vendors’ xHCI controllers (NVIDIA SoC internal xHCI, ASMedia ASM2142, and NEC uPD720200). I noticed that upstream Linux has a security fix CVE-2025-22022 for NEC uPD720200 series controllers: Ubuntu description: https://ubuntu.com/security/CVE-2025-22022 The corresponding upstream patch is titled: usb: xhci: Apply the link chain quirk on NEC isoc endpoints The description says that on NEC uPD720200 controllers, isochronous endpoints under missed service interval / bandwidth pressure can cause TRB DMA pointers to go out of range, leading to log messages like: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 2 comp_code 31/13 Looking for event-dma … trb-start … seg-start … This looks almost identical to what I am seeing on Orin NX, except that in my case I see it not only on NEC but also on the SoC xHCI and the ASMedia ASM2142 controller. Questions for NVIDIA engineers For the kernel I am currently running (5.15.148-tegra, nvidia-l4t-kernel 36.4.4), does Jetson Linux already include the upstream xHCI patch that fixes CVE-2025-22022? If yes, could you please point me to the exact commit or patch location in the Jetson kernel sources? In Jetson Linux, is this patch only enabled for NEC uPD720200 devices, or does it affect other controllers as well? If the current Jetson Linux kernel does not include this patch yet: Do you plan to integrate the CVE-2025-22022 fix into a future Jetson Linux release? For users who would like to validate this fix earlier, what is the recommended and safe way to backport it? For example: Is there an NVIDIA-provided patch bundle or test kernel that already contains this fix? If users need to integrate the upstream patch themselves, which official kernel source tree/branch should they start from, and what is the recommended process to rebuild and deploy the updated kernel on Jetson? Since I am seeing the same “Transfer event TRB DMA ptr not part of current TD” style error on multiple controllers (not only NEC uPD720200 but also the SoC’s on-board xHCI and the ASMedia ASM2142 PCIe–USB3 controller), I would like to ask: Does NVIDIA know of any other Jetson-specific causes or patches for this type of TRB pointer error (for example, additional quirks for ASM2142 or for the SoC-integrated xHCI)? For high-bandwidth multi-camera UVC use-cases on Orin NX, is there a recommended kernel version, patch set, or configuration that improves xHCI stability? Thank you very much for clarifying: The current status of CVE-2025-22022 handling in Jetson Linux, and How to integrate or select kernel versions/patches on Jetson when similar TRB errors appear across different xHCI controllers. If needed, I can provide full dmesg logs (including the surrounding context of these TRB errors), as well as PCIe/USB topology information and detailed test steps in a follow-up post.

Hi, It looks like the fix for CVE-2025-22022 is not included. Do you know where to get the patches? If we can find the patches, we can manually apply them by following developer guide. If you use custom board, we also suggest do USB compliance test, to ensure signal quality is good.

Hi, thanks for the reply and for confirming that the fix for CVE‑2025‑22022 is not yet included. I was able to locate the upstream patches for this issue, for example: Mainline Linux commit (torvalds tree): usb: xhci: Apply the link chain quirk on NEC isoc endpoints Making sure you're not a bot! And the corresponding stable backports listed by NVD: Making sure you're not a bot! Making sure you're not a bot! Making sure you're not a bot! Making sure you're not a bot! However, I am not very familiar with rebuilding the Jetson Linux kernel , so I would really appreciate some more concrete guidance. Could you please clarify the following for my specific environment? Hardware: Jetson Orin NX Developer Kit Jetson Linux / L4T: R36.4.x Kernel: 5.15.148-tegra Kernel package: nvidia-l4t-kernel 5.15.148-tegra-36.4.4-20250616085344 Which exact kernel source tree / branch should I start from for this L4T version? For example, is there an official nvidia-l4t-kernel-sources package or a git branch that corresponds exactly to 5.15.148-tegra-36.4.4 ? Once I have the correct kernel sources, should I apply the stable backport for 5.15 from the list above, and then rebuild the kernel following a specific section of the Jetson Linux Developer Guide? If possible, could you point me to the exact chapter / URL in the documentation that describes the recommended kernel rebuild process for R36.4.x? After rebuilding, what is the recommended way to install and boot the new kernel on Jetson (for example, which files need to be copied/updated, and whether there is a standard script or tool provided by NVIDIA for deploying a custom kernel on Orin NX)? Since I am not very experienced with kernel builds on Jetson, a short step‑by‑step outline (even at a high level) would be very helpful to avoid mistakes. Regarding USB compliance: I understand your suggestion. In parallel with the software changes, I will also consider USB signal integrity / compliance testing on my custom multi‑camera setup. Thank you again for your support.
