CVE-2026-19028 is an integer underflow vulnerability in the HDF5 library up to version 2.3.0. The flaw occurs in the Fletcher32 checksum filter implementation, where the code subtracts 4 bytes from the input buffer size without verifying the buffer length is at least 4 bytes. This can lead to a size_t underflow, causing a denial of service via out-of-bounds reads and application crashes when processing crafted HDF5 files with small Fletcher32-filtered chunks.
