NVD Description

Note: Versions mentioned in the description apply only to the upstream busybox-static package and not the busybox-static package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

An attacker-controlled pointer free in Busybox's hush applet leads to denial of service and possible code execution when processing a crafted shell command, due to the shell mishandling the &&& string. This may be used for remote code execution under rare conditions of filtered command input.
