Openshift Container Platform For Linuxone

Heap-based buffer overflow in GLib's g_escape_uri_string() function allows local attackers to achieve high-integrity and high-availability impacts through integer overflow in escaped string length calculation. The vulnerability affects Red Hat Enterprise Linux 9.0 and 10.0 across multiple architectures (x86_64, ARM64, IBM Z, PowerPC). Vendor patches are available via multiple RHSA advisories. Publicly available exploit code exists, but EPSS score remains extremely low (0.01%, 1st percentile), suggesting minimal real-world exploitation activity despite the availability of technical details.

Stack-based buffer overflow in libxml2's xmlBuildQName function allows remote unauthenticated attackers to crash affected systems via crafted XML input. The vulnerability affects libxml2 directly and downstream Red Hat products including OpenShift Container Platform 4.12-4.19, RHEL 7-10, and JBoss Core Services. With CVSS 7.5 (AV:N/AC:L/PR:N/UI:N), EPSS 0.75% (73rd percentile), and publicly available exploit code, this represents a moderate real-world risk focused on availability disruption rather than code execution or data compromise.
