Red Hat has issued a security advisory for the kernel-rt packages, which provide the Real Time Linux Kernel for systems requiring high determinism. The update addresses four vulnerabilities: a race condition in nouveau (CVE-2024-26984), a use-after-free in iscsi target code (CVE-2026-23193), a use-after-free in nf_tables_addchain() that can lead to privilege escalation or denial of service (CVE-2026-23231), and a double free vulnerability in the qla2xxx driver causing denial of service and potential privilege escalation (CVE-2025-71238). These vulnerabilities have a moderate security impact. The advisory includes updated packages for affected Red Hat Enterprise Linux 8 Real Time variants. Systems must be rebooted after applying the update for the fixes to take effect.

Red Hat has issued a security advisory for the kernel-rt packages, which provide the Real Time Linux Kernel for systems requiring high determinism. The update addresses multiple vulnerabilities including denial of service, use-after-free, privilege escalation, memory corruption, deadlocks, and heap overflow issues across various kernel components such as SCSI, ALSA, RDMA, KVM, and NFS. These vulnerabilities affect Red Hat Enterprise Linux 9. 0 and related products. The advisory rates the update as Important and requires a system reboot after applying the patch. No known exploits in the wild have been reported at this time.
