CVE-2026-35348: uutils coreutils has an Uncaught Exception When Encountering Valid but Non-UTF-8 Paths

The sort utility in uutils coreutils is vulnerable to a process panic when using the –files0-from option with inputs containing non-UTF-8 filenames. The implementation enforces UTF-8 encoding and utilizes expect(), causing an immediate crash when encountering valid but non-UTF-8 paths. This diverges from GNU sort, which treats filenames as raw bytes. A local attacker can exploit this to crash the utility and disrupt automated pipelines.
