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

Published Oct 29, 2026 · Updated Oct 29, 2026

Ecosystem: AlmaLinux

Summary

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: KVM: arm64: vgic: Handle race between interrupt affinity change and LPI disabling (CVE-2026-72288)
* kernel: KVM: arm64: vgic: Check the interrupt is still ours before migrating it (CVE-2026-72289)
* kernel: scsi: target: iscsi: Reserve a terminator byte for the login payload (CVE-2026-90011)
* kernel: KEYS: encrypted: fix integer overflow of datablob_len (CVE-2026-98222)

Bug Fix(es) and Enhancement(s):

* ipv4: ip_gre: make ipgre_header() robust (rhel-8.10.z) (JIRA:RHEL-271135)
* ip6_gre: make ip6gre_header() robust (rhel-8.10.z) (JIRA:RHEL-271136)
