CVE-2025-6750

Description

A flaw was found in hdf5. The H5O__mtime_new_encode function in src/H5Omtime.c contains a heap-based buffer overflow vulnerability that can be triggered by crafted input. A local attacker can exploit this condition by providing a specially constructed file. This manipulation may result in a denial of service.

Statement

The assigned severity is Low because the attack vector is local. An attacker would require local access to the system to exploit this vulnerability. It does not require any user interaction or special privileges. The impact is primarily on the availability of the service, potentially causing a denial of service.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
