CVE-2026-35380 Details
Description
A logic error in the cut utility of uutils coreutils causes the program to incorrectly interpret the literal two-byte string '' (two single quotes) as an empty delimiter. The implementation mistakenly maps this string to the NUL character for both the -d (delimiter) and --output-delimiter options. This vulnerability can lead to silent data corruption or logic errors in automated scripts and data pipelines that process strings containing these characters, as the utility may unintentionally split or join data on NUL bytes rather than the intended literal characters.
A logic error has been identified in the cut utility of uutils coreutils, specifically in version 0.8.0. The issue arises because the program misinterprets the literal two-byte string '' as an empty delimiter, incorrectly mapping it to the NUL character for both the delimiter and output-delimiter options. This vulnerability can cause silent data corruption or logic errors in automated scripts and data pipelines that handle strings with these characters, as the utility may unintentionally split or join data based on NUL bytes instead of the intended literal characters.
Users can update to uutils coreutils version 0.8.0 or later, where this vulnerability has been addressed.
