Canadian Cyber Centre flags vulnerabilities across many Red Hat products
The Canadian Centre for Cyber Security issued advisory AV26-1111 on 2 November 2026, stating that as of 30 October 2026 Red Hat products were affected by vulnerabilities. Listed products include Red Hat Build of Keycloak, Red Hat Enterprise Linux versions 6 to 10, JBoss Enterprise Application Platform 7 and 8, OpenShift Container Platform 4 and 5, and Red Hat Hardened Images, among others, with all versions shown as affected. Administrators should review Red Hat's linked security advisory and apply fixes as they are released.
Anthropic says its AI model built a working root exploit for critical Linux kernel flaw CVE-2026-98432
Anthropic says an unreleased Claude research model produced a zero-click exploit for CVE-2026-98432, a use-after-free race condition in the Linux kernel's IPv4 TCP handling that gives unauthenticated root command execution, with a claimed 9.8 CVSS score. Upstream fixes are available in stable branches such as 5.10.272, 5.15.223 and 6.6.159, but distribution fixes are uneven, with Ubuntu and Red Hat Enterprise Linux reportedly lacking patched kernels as of 30 October. Teams should prioritise internet-facing servers, apply vendor kernel updates, reboot, and check whether multipath TCP listeners are needed.
