While reproducing original reported CVE-2021-23210 which was for a FPE [1], we encountered this global-buffer-overflow (READ) issue which was triggerred using the same reproducer, this issue lies in the libsox component as well hence requesting a different CVE for this issue so it can be tracked accordingly
