CVE-2024-38612 remediation guide

Linux Linux, linux_kernel, acrn

In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix invalid unregister error path The error path of seg6_init() is wrong in case CONFIG_IPV6_SEG6_LWTUNNEL is not defined. In that case if seg6_hmac_init() fails, the genl_unregister_family() isn't called. This issue exist since commit 46738b1317e1 ("ipv6: sr: add option to control lwtunnel support"), and commit 5559cea2d5aa ("ipv6: sr: fix possible use-after-free and null-ptr-deref") replaced unregister_pernet_subsys() with genl_unregister_family() in this error path.

Identify the affected asset

Confirm whether Linux Linux, linux_kernel, acrn is installed, record the deployed version and installation path, and identify exposed interfaces.

Record the product name, package or appliance identifier, and installed version.
Identify internet-facing, administrative, API, and internal access paths.
Preserve the pre-change configuration and relevant service logs.

Validate the affected-version match

Compare the deployed version with the affected range: >= 46738b1317e169b281ad74690276916e24d1be6d < 10610575a3ac2a702bf5c57aa931beaf847949c7, >= 46738b1317e169b281ad74690276916e24d1be6d < 646cd236c55e2cb5f146fc41bbe4034c4af5b2a4, >= 46738b1317e169b281ad74690276916e24d1be6d < 00e6335329f23ac6cf3105931691674e28bc598c, >= 46738b1317e169b281ad74690276916e24d1be6d < 1a63730fb315bb1bab97edd69ff58ad45e04bb01, >= 46738b1317e169b281ad74690276916e24d1be6d < e77a3ec7ada84543e75722a1283785a6544de925, >= 46738b1317e169b281ad74690276916e24d1be6d < 3398a40dccb88d3a7eef378247a023a78472db66, >= 46738b1317e169b281ad74690276916e24d1be6d < 85a70ff1e572160f1eeb096ed48d09a1c9d4d89a, >= 46738b1317e169b281ad74690276916e24d1be6d < c04d6a914e890ccea4a9d11233009a2ee7978bf4, >= 46738b1317e169b281ad74690276916e24d1be6d < 160e9d2752181fcf18c662e74022d77d3164cd45, >= 4.10, >= 46738b1317e1 < 0610575a3ac, >= 46738b1317e1 < 646cd236c55e, >= 46738b1317e1 < 00e6335329f2, >= 46738b1317e1 < 1a63730fb315, >= 46738b1317e1 < e77a3ec7ada8, >= 46738b1317e1 < 3398a40dccb8, >= 46738b1317e1 < 85a70ff1e572, >= 46738b1317e1 < c04d6a914e89, >= 46738b1317e1 < 160e9d275218, < V3.1. Treat incomplete inventory results as unresolved.

Prioritize with independent signals

The CVSS severity warrants an early asset and exposure review. Combine this signal with asset criticality, exposure, compensating controls, and business impact.

Apply supported remediation

Follow the vendor advisory or supported update path. Current fixed-version status: 4.19.316, 5.4.278, 5.10.219, 5.15.161, 6.1.93, 6.6.33, 6.8.12, 6.9.3. Preserve configuration and rollback material before change.

Verify the result

Confirm the resulting version, service health, authentication and access paths, monitoring coverage, and relevant security logs.

Confirm the expected version and package state.
Run a functional health check for critical service paths.
Review authentication, error, application, and security monitoring logs.
Reassess exposure if the supported fix cannot be applied.

Operational boundary

This page does not replace the vendor advisory, support contract, change-management process, or recovery plan. Do not infer that an asset is unaffected from an incomplete inventory query or a missing fixed-version field.
