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: nfsd: don't ignore the return code of svc_proc_register() (CVE-2025-22026) * kernel: sctp: linearize cloned gso packets in sctp_rcv (CVE-2025-38718) 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.
AI Analysis
Technical Summary
Red Hat Product Security issued an advisory (RHSA-2025:17396) for Red Hat Enterprise Linux 10 kernel packages addressing two vulnerabilities: CVE-2025-22026, where the NFS daemon (nfsd) did not properly handle the return code of svc_proc_register(), and CVE-2025-38718, where the SCTP protocol failed to linearize cloned GSO packets in sctp_rcv. These issues have been fixed in updated kernel packages. The advisory rates the security impact as moderate and requires a system reboot after patch installation. The advisory covers multiple architectures and extended update support versions of Red Hat Enterprise Linux 10 and related CodeReady Linux Builder products.
Potential Impact
The vulnerabilities affect the Linux kernel's NFS daemon and SCTP protocol implementations, potentially leading to improper handling of certain kernel operations. The exact impact details are not provided in the advisory, but the security rating is moderate, indicating a limited but meaningful risk if exploited. No known exploits in the wild have been reported.
Mitigation Recommendations
Red Hat has released updated kernel packages that address these vulnerabilities. Users should apply the available kernel updates for Red Hat Enterprise Linux 10 as described in the Red Hat advisory RHSA-2025:17396 and reboot their systems to ensure the fixes take effect. For detailed update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigation steps are indicated by the vendor.
