  "description": "In the Linux kernel, the following vulnerability has been resolved:  ALSA: usb-audio: qcom: reject stream disable with no active interface  handle_uaudio_stream_req() resolves an interface index with info_idx_from_ifnum(), which returns -EINVAL when no interface matches. The enable branch and the response: cleanup label both guard against a negative index, but the disable branch does not: it forms info = \u0026uadev[pcm_card_num].info[info_idx] and dereferences it.  uadev[].info is a pointer allocated only when a stream is first enabled, so a negative info_idx on the disable path is unsafe in two ways:   - If the card was never enabled, .info is NULL and \u0026info[-EINVAL] is a    wild pointer; reading info-\u003Edata_ep_pipe faults (kernel oops).   - If the card was enabled at least once (.info allocated) and the    disable names an interface that does not match, \u0026info[-EINVAL] points    before the allocation; info-\u003Edata_ep_pipe / info-\u003Esync_ep_pipe are an    out-of-bounds slab read and, when non-zero, an out-of-bounds 4-byte    write (both pipe fields are cleared to 0). That is memory corruption,    not just a NULL dereference.  The request is reachable from unprivileged local userspace over AF_QIPCRTR. Reject a disable request with no resolved interface, matching the guard the enable path already has.",
