Technical Summary
This Red Hat security advisory (RHSA-2025:12662) covers multiple vulnerabilities in the Linux kernel packages for Red Hat Enterprise Linux 10. The fixes address use-after-free and slab-use-after-free vulnerabilities in components including padata (CVE-2025-21727), HID intel-ish-hid (CVE-2025-21928, CVE-2025-21929), memstick rtsx_usb_ms (CVE-2025-22020), ext4 journaling (CVE-2025-22113), RDMA core (CVE-2025-22085), net_sched hfsc (CVE-2025-37890), net/tipc (CVE-2025-38052), net ch9200 (CVE-2025-38086), net_sched taprio_dev_notifier (CVE-2025-38087), and nvme-tcp (CVE-2025-38264). The advisory provides updated kernel packages for multiple architectures and variants of Red Hat Enterprise Linux 10. The update is rated as important by Red Hat Product Security. The system must be rebooted after applying the update for the fixes to take effect.
Potential Impact
The vulnerabilities include multiple use-after-free and slab-use-after-free issues in critical kernel components, which could lead to system instability, crashes, or potential escalation of privileges if exploited. The advisory does not report known exploits in the wild. The impact is rated as important by Red Hat, indicating a significant security risk if unpatched.
Mitigation Recommendations
Red Hat has released updated kernel packages that address these vulnerabilities. Users of Red Hat Enterprise Linux 10 and related variants should apply the kernel update as provided in advisory RHSA-2025:12662. A system reboot is required for the update to take effect. There are no indications that additional mitigations are necessary beyond applying the official update and rebooting.
