Important: kernel-rt security, bug fix, and enhancement update

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): * kernel: scsi: target: iscsi: Fix use-after-free in iscsit_dec_conn_usage_count() (CVE-2026-23216) * kernel: gfs2: Fix use-after-free in iomap inline data write path (CVE-2026-45984) * kernel: RDMA/vmw_pvrdma: Fix double free on pvrdma_alloc_ucontext() error path (CVE-2026-46189) Bug Fix(es) and Enhancement(s): * [AlmaLinux 8.10.z] Add an .sbat section to the x86 kernel (JIRA:AlmaLinux-182788) * Incorrect message "NFS: Server wrote zero bytes" is shown in the logs (JIRA:AlmaLinux-147665) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
