All standard RHEL 8+ architectures (x86_64, aarch64, ppc64le, s390x) are 64-bit and not affected. The vulnerability is applicable only to legacy 32-bit builds or embedded environments. On affected 32-bit platforms, the integer overflow leads to heap corruption with controlled writes, which could potentially enable code execution.", "threat_severity": "Moderate"}
