dwc2 HCD urb_dequeue path is reached from local usbfs ioctls (USBDEVFS_SUBMITURB/DISCARDURB) on /dev/bus/usb device nodes, as well as from kernel unlink paths during USB I/O cancellation on dwc2-equipped embedded systems, kiosks, and mobile OTG hosts.\nAC:L - Once debug is enabled, an attacker can reliably drive the path by submitting and cancelling URBs (or forcing disconnect/error unlink storms) and can control the HCD_BH giveback race by running concurrent cancellation requests.\nPR:L - Triggering urb dequeue via usbfs requires only local user access to a USB device node (typically root or plugdev-group membership), which is low privilege and commonly available on dwc2 embedded platforms; no real root in the init namespace is required.\nUI:N - Exploitation requires only the attacker to submit and cancel USB transfers (or insert/disconnect a malicious USB device); no action by a separate victim user is needed.\nS:U - The UAF corrupts kernel heap memory within the kernel's own security authority and does not by itself cross a VM, container, or IOMMU boundary.\nC:H - Use-after-free of a kmalloc-backed struct urb after giveback can be groomed via heap spraying to obtain arbitrary kernel memory read primitives, not merely a bounded leak.\nI:H - UAF on the URB object in the general kmalloc slab enables attacker-controlled reuse of freed memory, supporting control-flow hijack and arbitrary kernel write/code execution.\nA:H - The post-giveback dereference can cause kernel oops/panic during URB teardown, and successful UAF exploitation can crash or hang the system."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles":
