FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

hdf5: HDF5 Heap Buffer Overflow
A vulnerability classified as problematic was found in HDF5 1.14.6. This vulnerability affects the function H5FS__sinfo_serialize_node_cb of the file src/H5FScache.c. The manipulation leads to heap-based buffer overflow. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used.
A flaw was found in HDF5. The `H5FS__sinfo_serialize_node_cb` function in `src/H5FScache.c` contains a heap-based buffer overflow triggered by manipulation, requiring local access. This overflow occurs during the serialization of file system information nodes. This vulnerability allows a local attacker to cause an application-level denial of service.
