How to Fix CVE-2026-35378

To remediate this vulnerability, upgrade all affected Coreutils dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

coreutils fixed: 0.8.0 
Upgrade coreutils to 0.8.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for coreutils

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-35378, inspect your project dependencies for Coreutils:

inspect dependencies for coreutils

Analyze the terminal output to locate any version of Coreutils in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.8.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-768: Incorrect Short Circuit Evaluation, where the product contains a conditional statement with multiple logical expressions in which one of the non-leading expressions may produce side effects. this may lead to an unexpected state in the program after the execution of the conditional, because short-circuiting logic may prevent the side effects from occurring. In Coreutils, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A logic error in the expr utility of uutils coreutils causes the program to evaluate parenthesized subexpressions during the parsing phase rather than at the execution phase. This implementation flaw prevents the utility from performing proper short-circuiting for logical OR (|) and AND (&) operations. As a result, arithmetic errors (such as division by zero) occurring within "dead" branches, branches that should be ignored due to short-circuiting, are raised as fatal errors. This divergence from GNU expr behavior can cause guarded expressions within shell scripts to fail with hard errors instead of returning expected boolean results, leading to premature script termination and breaking GNU-compatible shell control flow.
