AI-suggested

If you cannot patch yet, users should exercise caution when using the mv utility on directory trees containing symbolic links across filesystem boundaries, especially with untrusted or sensitive data. Avoid moving directories with complex symlink structures or consider alternative tools that correctly preserve symlinks.

Description

The mv utility in uutils coreutils improperly handles symbolic links when moving directory trees across filesystem boundaries by expanding symlinks instead of preserving them. This behavior can cause resource exhaustion, unexpected duplication of sensitive data, or infinite recursion due to symlink loops. The vulnerability is tracked as CVE-2026-35365 with a medium severity rating and a CVSS score of 6.6.
