Red Hat Security Advisory: kernel security update
The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: ublk: make sure ubq->canceling is set when queue is frozen (CVE-2025-22068) * kernel: nfsd: handle get_client_locked() failure in nfsd4_setclientid_confirm() (CVE-2025-38724) * kernel: mm/memory-failure: fix VM_BUG_ON_PAGE(PagePoisoned(page)) when unpoison memory (CVE-2025-39883) * kernel: e1000e: fix heap overflow in e1000_set_eeprom (CVE-2025-39898) * kernel: wifi: mt76: fix linked list corruption (CVE-2025-39918) * kernel: i40e: fix idx validation in config queues msg (CVE-2025-39971) 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.

Technical Summary
This Red Hat security advisory (RHSA-2025:22395) addresses multiple vulnerabilities in the Linux kernel packages used in Red Hat Enterprise Linux 10. The fixes include: ensuring the ubq->canceling flag is set when the ublk queue is frozen (CVE-2025-22068), handling failure in get_client_locked() during NFSv4 client ID confirmation (CVE-2025-38724), correcting a VM_BUG_ON_PAGE triggered by unpoisoning memory (CVE-2025-39883), fixing a heap overflow in the e1000e network driver EEPROM setting function (CVE-2025-39898), resolving linked list corruption in the mt76 wifi driver (CVE-2025-39918), and validating index parameters in i40e network driver queue configuration messages (CVE-2025-39971). These fixes address various memory safety and validation issues. The advisory applies to Red Hat Enterprise Linux 10 and related CodeReady Linux Builder and Extended Update Support versions. The update requires a system reboot to take effect.
Potential Impact
The vulnerabilities fixed by this advisory affect core kernel components and device drivers, potentially leading to memory corruption, heap overflow, linked list corruption, and improper handling of client locking in NFS. These issues could cause system instability or crashes and may be exploitable to compromise system integrity or availability. The overall security impact is rated moderate by Red Hat.
Mitigation Recommendations
Red Hat has released an official kernel update for Red Hat Enterprise Linux 10 that addresses these vulnerabilities. Users should apply the update as described in the advisory (https://access.redhat.com/articles/11258) and reboot affected systems to ensure the fixes take effect. No additional mitigations are specified or required beyond applying the official patch and rebooting.
