CVE-2026-19028

A flaw was found in HDF5. An attacker can craft a malicious HDF5 file with a specially designed Fletcher32-filtered chunk. When this file is processed, an integer underflow occurs due to insufficient size validation, leading to a massive out-of-bounds read. This vulnerability can cause the...

EUVD-2026-53676

H5Zfilterfletcher32 in H5Zfletcher32.c in HDF5 through 2.3.0 computes the data length to checksum by subtracting the 4-byte trailing checksum size from the input buffer size without checking that the buffer is at least 4 bytes, allowing a sizet underflow. This allows attackers to cause a denial o...
