Common Weakness Enumeration

CWE-768

Allowed

Incorrect Short Circuit Evaluation

Abstraction: Variant · Status: Incomplete

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.

CVE-2026-35378 (GCVE-0-2026-35378)

Vulnerability from cvelistv5 – Published: 2026-04-22 16:09 – Updated: 2026-04-22 17:00

Title

uutils coreutils expr Local Denial of Service via Eager Evaluation of Parenthesized Subexpressions

Summary

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.

Severity

3.3 (Low)

Mitigation

Implementation

Minimizing the number of statements in a conditional that produce side effects will help to prevent the likelihood of short circuit evaluation to alter control flow in an unexpected way.
