CVE-2026-19023
Overview
CVE-2026-19023 is a known-severity vulnerability. It was published on August 5, 2026.
Technical Description
Untrusted pointer dereference in the render_bin_output function in the h5dump tool in HDF5 before 2.3.0 allows attackers to cause a denial of service via a variable-length string dataset with more than one element dumped in binary mode, which corrupts the per-element stride calculation and causes subsequent elements to be read from a misaligned offset and dereferenced as a pointer.
