  "description": "In the Linux kernel, the following vulnerability has been resolved:  usb: gadget: f_uac1_legacy: validate control request size  f_audio_complete() copies req-\u003Elength bytes into a 4-byte stack variable:    u32 data = 0;   memcpy(\u0026data, req-\u003Ebuf, req-\u003Elength);  req-\u003Elength is derived from the host-controlled USB request path, which can lead to a stack out-of-bounds write.  Validate req-\u003Eactual against the expected payload size for the supported control selectors and decode only the expected amount of data.  This avoids copying a host-influenced length into a fixed-size stack object.",
