View on CVE.org

Published Oct 30, 2026 CVSS 3.1 · 3.7 Low EPSS < 1% KEV · Not listed

Description

A flaw was found in gcc. An attacker could cause a Denial of Service (DoS) by passing a string that is not null-terminated to the std::from_chars() function in the libstdc++ library. This issue triggers an out-of-bounds read beyond the allocated buffer, potentially leading to invalid data parsing or an application crash.
