Summary
The GCC compiler's C++ standard library (libstdc++), specifically its parallel search functionality, is affected, impacting applications built with parallel mode enabled. A local attacker who supplies crafted search input can trigger an out-of-bounds memory access that crashes the application, resulting in a denial of service.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original description
A flaw was found in GCC. An out-of-bounds memory access vulnerability exists in the libstdc++ parallel search implementation due to an undersized internal buffer. A local attacker can exploit this flaw by providing crafted search data to an application compiled with parallel mode, causing the process to crash and leading to a Denial of Service (DoS).
