Race condition within a thread in Linux kernel - CVE-2024-27404

Published: June 8, 2024 / Updated: May 13, 2025


Vulnerability identifier: #VU91428
CSH Severity: Low
CVSS v4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]
CVE-ID: CVE-2024-27404
CWE-ID: CWE-366
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows a local user to manipulate data.

The vulnerability exists due to a data race within the subflow_finish_connect(), __mptcp_subflow_connect() and subflow_ulp_clone() functions in net/mptcp/subflow.c, within the fill_remote_addresses_vec() and mptcp_pm_nl_rm_addr_or_subflow() functions in net/mptcp/pm_netlink.c. A local user can manipulate data.
