NVD description

In the Linux kernel, the following vulnerability has been resolved: media: rc: igorplugusb: fix control request setup packet Commit eac69475b01f ("media: rc: igorplugusb: heed coherency rules") changed the control request storage from an embedded struct to an allocated pointer so it can obey DMA coherency rules. However, the driver still passes &ir->request to usb_fill_control_urb(). That points the URB setup packet at the pointer field itself rather than at the allocated struct usb_ctrlrequest. USB core then interprets pointer bytes as the setup packet. This can produce an invalid bRequestType and trigger the control direction warning reported by syzbot: usb 2-1: BOGUS control dir, pipe 80003580 doesn't match bRequestType 0 Pass ir->request itself as the setup packet.

    @OpenAI A Linux kernel fix I authored for the igorplugusb driver was later assigned CVE-2026-64240. I combined C-level kernel and USB-driver debugging with an agentic AI-assisted (Codex) workflow for research organization, commit/patch-context analysis, documentation, and validation planning. I retained responsibility for the technical investigation, patch, testing, and final decisions. CVE: https://www.cve.org/CVERecord?id=CVE-2026-64240 Commit: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e823e4294511989f5962e7ad85bf4d179ba74f52 #Linux #Cybersecurity #AISecurity #AIEngineering #Codex
