vulnerability than CVE-2021-40153. A squashfs filesystem that has been crafted to include a symbolic link
and then contents under the same filename in a filesystem can cause unsquashfs to first create the

the unsquashfs process to write through the symbolic link elsewhere in the filesystem. (CVE-2021-41072)
