Red Hat released moderate-severity Linux kernel security updates for RHEL 10 and RHEL 8 Real Time deployments, addressing flaws in ublk, NFS server handling, memory-failure processing, Intel e1000e and i40e drivers, and the mt76 Wi-Fi driver. The affected RHEL 10 offerings include standard, Extended Update Support, extended-life-cycle, four-year-support, and CodeReady Linux Builder repositories across x86_64, ARM64, IBM Z/s390x, and Power little-endian platforms.
The updates remediate CVE-2025-39918, a linked-list corruption issue in the mt76 driver caused by scheduled WCID entries remaining on a temporary stack list; Red Hat also issued fixes for RHEL 9 and RHEL 9.6 EUS. RHEL 8 kernel-rt packages fix CVE-2025-39697, an NFS race condition during updates to an existing write, and CVE-2025-39971, insufficient index validation in an i40e configuration-queues message. Organizations should install the applicable updated kernel or kernel-rt packages and reboot affected systems to activate the fixes.
