https://notcve.org/view.php?id=CVE-2021-47448
22 May 2024 — In the Linux kernel, the following vulnerability has been resolved: mptcp: fix possible stall on recvmsg() recvmsg() can enter an infinite loop if the caller provides the MSG_WAITALL, the data present in the receive queue is not sufficient to fulfill the request, and no more data is received by the peer. When the above happens, mptcp_wait_data() will always return with no wait, as the MPTCP_DATA_READY flag checked by such function is set and never cleared in such code path. Leveraging the above syzbot was a... • https://git.kernel.org/stable/c/7a6a6cbc3e592e339ad23e4e8ede9a3f6160bda8 •
