No cable, hardware, or network access is involved, matching the AV:L used for other dummy_hcd/gadget bugs.\nAC:L - The attacker controls both sides of the race: it queues small IN requests on one CPU in a tight loop while the periodic 1 ms `dummy_timer` frame processing performs giveback on another, and the fast-path guard (`list_empty(&fifo_req.queue)`) is cleared before the callback returns, so the window is entered on essentially every iteration and can be retried indefinitely.\nPR:L - No capability check exists anywhere on the path \u2014 `dummy_queue()` and the giveback sites perform none; reachability is gated only by node/mount permissions on /dev/raw-gadget, gadgetfs or the gadget configfs/functionfs tree, which on Android and embedded/industrial systems are routinely delegated to non-root system accounts, so basic local access suffices.\nUI:N - The attacker performs every step itself \u2014 enabling the gadget, queueing the IN transfers, and letting the emulated frame timer run \u2014 with no action required from any other user or victim.\nS:U - The corrupted object and the resulting control-flow hijack are entirely within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The in-flight copy overwrites `fifo_req.req.buf`, `length`, `actual` and `context` of the live shared request, so the completion path and the host-side `transfer()` memcpy operate with mismatched buffer/length/context pairs, letting an attacker steer reads out of unintended kernel memory and surface them through the emulated host transfer \u2014 a kernel memory disclosure primitive.\nI:H - `req->req = *_req` clobbers the `complete` function pointer while `usb_gadget_giveback_request()` is dereferencing it, giving a torn/stale indirect call plus a `context` mismatch (type confusion) that is a direct control-flow hijack primitive; the same race also lets the shared `fifo_buf` be written under a stale length, yielding controllable kernel writes.\nA:H - The reported effect is a general protection fault / kernel page fault in `dummy_timer` (syzbot faf3a6cf579fc65591ca) from calling through the clobbered pointer, i.e. a kernel oops that an unprivileged local attacker can trigger repeatedly."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
