Vulnerability from gsd

Details
** DISPUTED ** snd_ctl_elem_add in sound/core/control.c in the Linux kernel through 5.6.3 has a count=info->owner line, which later affects a private_size*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, SNDRV_CTL_IOCTL_ELEM_ADD and SNDRV_CTL_IOCTL_ELEM_REPLACE, have been designed to misuse the info->owner field in a safe way.
