CVE-2026-0992
2.9 · LOWOverview
CVE-2026-0992 is a low-severity vulnerability affecting redhat hardened_images. It was published on January 15, 2026 and has a CVSS 3.1 base score of 2.9 (LOW).
This vulnerability has a CVSS 3.1 base score of 2.9, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated <nextCatalog> elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted catalogs, causing the parser to redundantly traverse catalog chains. This leads to excessive CPU consumption and degrades application availability, resulting in a denial-of-service condition.
Remediation
Check the references section for vendor advisories and patches from redhat. Update hardened_images to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
