What is CVE-2026-114690?

A flaw in the GCC project's libstdc++ library has been identified, which results in an out-of-bounds memory access during the parallel search implementation. This vulnerability arises from an undersized internal buffer, allowing a local attacker to exploit it. By feeding crafted search data to an application compiled in parallel mode, it can provoke a crash in the process, thereby causing a Denial of Service (DoS) condition. This vulnerability emphasizes the importance of careful buffer management when designing parallel processing capabilities in software applications.
