This Red Hat security advisory addresses multiple moderate severity vulnerabilities in the Linux kernel packages for Red Hat Enterprise Linux 8. The issues include use-after-free bugs in RDMA/iwcm and tipc components, a memcpy usage fix in the scsi lpfc BIOS version handling, and a race condition in the net/sched sch_qfq module. These vulnerabilities could potentially lead to stability or security issues in affected systems. The advisory provides updated kernel packages to fix these vulnerabilities and requires a system reboot to apply the updates.

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: net_sched: hfsc: Fix a potential UAF in hfsc_dequeue() too (CVE-2025-37823) * kernel: i40e: fix MMIO write access to an invalid page in i40e_clear_hw (CVE-2025-38200) * kernel: RDMA/iwcm: Fix use-after-free of work objects after cm_id destruction (CVE-2025-38211) * kernel: net/sched: Always pass notifications when child class becomes empty (CVE-2025-38350) * kernel: tipc: Fix use-after-free in tipc_conn_close() (CVE-2025-38464) * kernel: vsock: Fix transport_* TOCTOU (CVE-2025-38461) * kernel: xfrm: interface: fix use-after-free after changing collect_md xfrm interface (CVE-2025-38500) 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.

Red Hat has issued a security advisory for the kernel-rt packages, which provide the Real Time Linux Kernel for systems requiring high determinism. The update addresses two use-after-free vulnerabilities: one in the RDMA/iwcm component after cm_id destruction (CVE-2025-38211), and another in the tipc_conn_close() function (CVE-2025-38464). These vulnerabilities could lead to memory corruption issues. The advisory rates the security impact as Moderate. A patch is available and applying the update requires a system reboot. The affected products include Red Hat Enterprise Linux for Real Time 8 and related variants.

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: nfsd: cancel nfsd_shrinker_work using sync mode in nfs4_state_shutdown_net (CVE-2024-50121) * kernel: udp: Fix memory accounting leak. (CVE-2025-22058) * kernel: usb: dwc3: gadget: check that event count does not exceed event buffer length (CVE-2025-37810) * kernel: RDMA/iwcm: Fix use-after-free of work objects after cm_id destruction (CVE-2025-38211) * kernel: vsock: Fix transport_* TOCTOU (CVE-2025-38461) 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.
