Last modified Jun 17, 2026

CVE-2026-35348 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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. EPSS estimates a 0.13% chance of exploitation in the next 30 days.

Description

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.
