sndctlelemadd in sound/core/control.c in the Linux kernel through 5.6.3 has a count=info->owner line, which later affects a privatesize*count multiplication for unspecified "interesting side effects." NOTE: kernel engineers dispute this finding, because it could be relevant only if new callers were added that were unfamiliar with the misuse of the info->owner field to represent data unrelated to the "owner" concept. The existing callers, SNDRVCTLIOCTLELEMADD and SNDRVCTLIOCTLELEMREPLACE, have been designed to misuse the info->owner field in a safe way
