In the Linux kernel, the following vulnerability has been resolved: usb: gadget: dummyhcd: prevent fiforeq reuse during giveback dummyhcd embeds a single shared usbrequest dum-fiforeq that the "emulated single-request FIFO" fast-path in dummyqueue reuses for small IN transfers: it copies the...

CVE-2026-68370

CVE-2026-68370 concerns Linux kernel usb gadget dummy_hcd. The vulnerability arose from reusing a single shared usb_request (fifo_req) for small IN transfers in an emulated FIFO path. The code copied the caller’s request into fifo_req and queued it, while completion side actions (dummy_timer/dumm...
