Multiple vulnerabilities in the Red Hat Linux kernel could allow a remote attacker to trigger denial of service, remote code execution, data manipulation, or security restriction bypass. The affected systems include Red Hat Enterprise Linux versions 9.0 and 10.0, as well as Red Hat OpenShift Container Platform 4.17, across multiple architectures (x86_64, ARM 64, IBM Z, and Power). Patches are available via the provided Red Hat security advisories (RHSA-2026:0701, RHSA-2026:22147, RHSA-2026:22334), and administrators should apply these fixes immediately.
