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: i40e: Do not allow untrusted VF to remove administratively set MAC (CVE-2024-26830) * kernel: net/sched: Fix UAF when resolving a clash (CVE-2024-41040) * kernel: mptcp: cope racing subflow creation in mptcp_rcv_space_adjust (CVE-2024-53122) 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
The advisory covers three kernel vulnerabilities: CVE-2024-26830 fixes an issue in the i40e driver where untrusted virtual functions could remove administratively set MAC addresses; CVE-2024-41040 addresses a use-after-free (UAF) bug in the network scheduler when resolving clashes; CVE-2024-53122 mitigates a race condition in multipath TCP subflow creation within mptcp_rcv_space_adjust. These vulnerabilities affect the Linux kernel in Red Hat Enterprise Linux 9.2 Extended Update Support and related builds. The vendor has released updated kernel packages to remediate these issues, requiring a system reboot to activate the fixes.
Potential Impact
Successful exploitation could allow unauthorized modification of network interface configurations (CVE-2024-26830), potential memory corruption or instability due to use-after-free (CVE-2024-41040), and issues related to race conditions in multipath TCP subflow creation (CVE-2024-53122). These could lead to denial of service or other unintended kernel behavior. The advisory rates the security impact as Important (high severity). No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released updated kernel packages addressing these vulnerabilities for Red Hat Enterprise Linux 9.2 Extended Update Support and related variants. Users should apply the provided kernel updates as detailed in the Red Hat advisory (RHSA-2025:0063) and reboot affected systems to ensure the fixes take effect. Patch status is confirmed with an official fix available. No additional mitigations are specified beyond applying the update and rebooting.
