CVE-2025-38552

The CVE-2025-38552 entry concerns a race in Multipath TCP (mptcp) within the Linux kernel, where subflow creation could race with subflow failure. The reported fix uses a separate flag, protected by the socket fallback lock, to track the condition that prevents any additional subflow creation, wi...

CVE-2025-38552 mptcp: plug races between subflow fail and subflow creation

In the Linux kernel, the following vulnerability has been resolved: mptcp: plug races between subflow fail and subflow creation We have races similar to the one addressed by the previous patch between subflow failing and additional subflow creation. They are just harder to trigger. The solution i...
