CVE-2024-27404

A race condition vulnerability was found in the Linux kernel remote_id function. Successful exploitation of the flaw can result in loss of system availability.

This vulnerability is rated as Moderate impact for Red Hat Enterprise Linux because exploitation requires local access to trigger concurrent Multipath TCP (MPTCP) operations, and the blast radius is confined to a denial of service without compromising confidentiality or integrity. The concurrency flaw in the handling of remote_id values does not allow arbitrary code execution or privilege escalation. Furthermore, MPTCP is not widely utilized in default server environments, restricting exposure to systems with specific multipath networking configurations.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
