Untrusted pointer dereference in the render_bin_output function in the h5dump tool in HDF5 before 2.1.1 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.

CVE-2026-19023 is a medium severity vulnerability in The HDF Group's HDF5 software, affecting versions before 2.1.1. It involves an untrusted pointer dereference in the h5dump tool's render_bin_output function. This flaw can cause a denial of service when processing variable-length string datasets with multiple elements in binary dump mode, due to corrupted stride calculations leading to misaligned pointer dereferences.
