AI-suggested

Red Hat states that no mitigation is currently available or meets their criteria for ease of use, applicability, or stability. Users should monitor Red Hat advisories for any future fixes or mitigations.

Description

A vulnerability in the libstdc++ component of GCC allows an attacker to trigger an integer wrap by providing an excessively large element count to a std::vector<bool> constructor. This leads to an inconsistent container state and out-of-bounds memory access, causing application crashes or Denial of Service (DoS). Exploitation requires attacker-controlled near-maximum integer values during container initialization, limiting the practical exposure. No mitigation is currently available that meets Red Hat's criteria, and the vulnerability is rated moderate severity.
