AI-suggested
Red Hat has released updated libxml2 packages (libxml2-2.15.2-0.3.hum1 and related RPMs) that address this vulnerability. Applying these official updates to Red Hat Hardened Images will remediate the issue. Refer to the Red Hat advisory RHSA-2026:7519 for detailed update instructions. No additional mitigation is required beyond applying the vendor-provided fix.
Description
A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested <include> directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk.
