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: nvme: avoid double free special payload (CVE-2024-41073) * kernel: net: qlogic/qede: fix potential out-of-bounds read in qede_tpa_cont() and qede_tpa_end() (CVE-2025-40252) * kernel: crypto: asymmetric_keys - prevent overflow in asymmetric_key_generate_id (CVE-2025-68724) * kernel: nfsd: fix heap overflow in NFSv4.0 LOCK replay cache (CVE-2026-31402) * kernel: Linux kernel KVM: Privilege escalation or denial of service due to improper shadow page table entry handling (CVE-2026-23401) * kernel: crypto: algif_aead - Revert to operating out-of-place (CVE-2026-31431) 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 covers a kernel update for Red Hat Enterprise Linux 8.8 that fixes several vulnerabilities: CVE-2024-41073 (nvme double free special payload), CVE-2025-40170 (net: use dst_dev_rcu() in sk_setup_caps()), CVE-2025-40135 and CVE-2025-40158 (ipv6: use RCU in ip6_xmit() and ip6_output()), CVE-2026-23216 (scsi target iscsi use-after-free), CVE-2026-43037 and CVE-2026-43038 (clearing skb2->cb[] in ip6_tunnel and ipv6 icmp error handling). These fixes address memory corruption and use-after-free issues in core kernel components. The advisory references Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions and Telecommunications Update Service, including ppc64le architecture. The update requires a reboot to apply.
Potential Impact
The vulnerabilities fixed could lead to memory corruption issues such as double free and use-after-free, potentially causing system instability or allowing an attacker to execute arbitrary code or cause denial of service. The affected components include NVMe storage drivers, network stack, IPv6 processing, and SCSI iSCSI target functionality. The overall security impact is rated as important by Red Hat, indicating a high risk if left unpatched.
Mitigation Recommendations
Red Hat has released an official kernel update for Red Hat Enterprise Linux 8.8 that addresses these vulnerabilities. Users should apply the update promptly following Red Hat's guidance at https://access.redhat.com/articles/11258. A system reboot is required for the update to take effect. No additional mitigations are indicated by the vendor advisory.
