RHSA-2026:33486 — Red Hat Security Advisory: kernel security, bug fix, and enhancement update

Red Hat’s advisory describes multiple Linux kernel vulnerabilities. Some may allow a low-privileged local attacker to escalate to root privileges, modify sensitive files, or read sensitive data. The IPv6 tunnel flaw may be triggered remotely with malicious ICMPv6 error messages, causing a kernel crash and potentially allowing code execution with kernel privileges.
