It looked like it started after the introduction of some fixes [2]. After analysis from Paolo, these patches revealed existing bugs, that should be fixed by the following patches. - Patch 1: Make sure ACK are sent when MPTCP-level window re-opens. In some corner cases, the other peer was not notified when more data could be sent. A fix for v5.11, but depending on a feature introduced in v5.19. - Patch 2: Fix spurious wake-up under memory pressure. In this situation, the userspace could be invited to read data not being there yet. A fix for v6.7. - Patch 3: Fix a false positive error when running the MPTCP Connect selftest with the "disconnect" cases. The userspace could disconnect the socket too soon, which would reset (MP_FASTCLOSE) the connection, interpreted as an error by the test. A fix for v5.17.
