• Out-of-Bounds Memory Access in MemoryMappedFile::atomic_buffer() UnitedTraders/aeron-rs#31

Severity

Out-of-bounds memory access / segfault. MemoryMappedFile::atomic_buffer() performs unchecked pointer arithmetic without validating that offset + length fits within the mapped file size. Triggerable from safe code.
