CVE-2026-17573 [MEDIUM] CWE-763 hdf5: HDF5 library: Denial of Service via crafted HDF5 file processing
hdf5: HDF5 library: Denial of Service via crafted HDF5 file processing
A flaw was found in the HDF5 library. A local user could exploit a double free vulnerability by processing a specially crafted HDF5 file with an oversized chunk size field using the h5repack tool. This could cause the application to unexpectedly terminate, leading to a denial of service.
Statement: This Moderate severity flaw in the HDF5 library can lead to a denial of service. It requires a local attacker to trick a user into processing a specially crafted HDF5 file with the `h5repack` utility, which could cause the application to crash due to a double free vulnerability.
