What to do

AI-suggested

Red Hat has released patched kernel packages for affected Red Hat Enterprise Linux 8.4 versions. Users should apply the kernel update as detailed in the Red Hat advisory (https://access.redhat.com/articles/11258) and reboot their systems to activate the fixes. Red Hat strongly advises against delaying the update to avoid exposure to these vulnerabilities.

Description

Red Hat has issued a security advisory for the Linux kernel packages addressing two vulnerabilities: CVE-2026-72129 and CVE-2026-74705. The first vulnerability involves the nvmet-rdma component handling inline data with a nonzero offset, and the second involves a potential use-after-free in UDP tunnel segmentation. These issues affect Red Hat Enterprise Linux 8.4 variants. A kernel update is available that fixes these vulnerabilities, and a system reboot is required for the update to take effect. Red Hat rates the security impact as Important and recommends prompt application of the update.
