AI-suggested
Red Hat has released updated libxml2 RPM packages as part of a security advisory (RHSA-2026:7519) that address this vulnerability. Users of Red Hat Hardened Images should apply these official updates to remediate the issue. Patch status is confirmed by the vendor advisory. No additional mitigation actions are indicated.
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.
