GCC’s libgomp library has been updated to include overflow checks in its aligned memory allocation functions, gomp_aligned_alloc and omp_aligned_alloc. This addresses potential vulnerabilities, particularly on platforms like MinGW where _aligned_alloc might not perform its own overflow checking, ensuring safer memory management.
