Linux Distros Unpatched Vulnerability : CVE-2026-26199

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - HDF5 is a high-performance library and a file format specification that implements the HDF5 data model. If H5Igetname is invoked on a group id with 0 for the si...

CVE-2026-26199

A flaw was found in HDF5, a library used for managing large datasets. This vulnerability occurs when a specific function, H5Igetname, is called with an invalid size parameter, leading to a buffer underflow. An attacker could exploit this by providing specially crafted input, potentially causing t...

UBUNTU-CVE-2026-26197

HDF5 is a high-performance library and a file format specification that implements the HDF5 data model. If a file is corrupted such that an array datatype's size, the number of elements, and the element size are not in agreement it can trigger an out of bounds read. The array datatype stores the...

CVE-2026-26199

The CVE-2026-26199 entry describes a buffer underflow in HDF5 when calling H5Iget_name (and H5G_get_name) with a size of zero. Under conditions where an ID is queried with size forced to zero and there is significant data before the name buffer, the function may fail to place a null terminator, l...

CVE-2026-26199 Buffer underflow in `H5Iget_name `/`H5G_get_name` if size is zero

HDF5 is a high-performance library and a file format specification that implements the HDF5 data model. If H5Igetname is invoked on a group id with 0 for the size parameter, it will underflow when trying to place a null terminator in the buffer. This can occur if H5Igetname is invoked in a way...
