RLSA-2026:99133: Important: kernel security, bug fix, and enhancement update

Q: Which package variants are within the scope of this update?

The advisory lists rocky-linux/kernel-rt, kernel-rt-debug-modules-core, kernel-uki-virt, kernel-debug, kernel-devel-matched, kernel-debug-uki-virt, kernel-modules-extra-matched, and kernel-rt-modules-core.

Q: What does the supplied severity vector indicate about exploitation?

The supplied CVSS vector indicates network-reachable exploitation with low privileges and no user interaction. It indicates high confidentiality, integrity, and availability impact, with unchanged scope.

Q: How can I determine whether a system needs this update?

Check whether the system has any of the listed Rocky Linux kernel package variants installed. The provided data does not include affected or fixed package versions, so version-level determination requires consulting the vendor advisory.
