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:15.6 relevant fixed versions and status.

A flaw was found in BusyBox. This vulnerability allows an attacker to modify files outside of the intended extraction directory by crafting a malicious tar archive containing unvalidated hardlink or symlink entries. If the tar archive is extracted with elevated privileges, this flaw can lead to privilege escalation, enabling an attacker to gain unauthorized access to critical system files.
