CVE-2026-35378
Description
A flaw was found in the expr utility of uutils coreutils. A logic error in how the utility evaluates parenthesized subexpressions prevents proper short-circuiting for logical OR and AND operations. This can lead to arithmetic errors, such as division by zero, in parts of expressions that should be ignored. Consequently, shell scripts using expr may terminate prematurely with fatal errors, disrupting expected control flow and potentially leading to a Denial of Service (DoS) for affected applications.
