CVE-2022-48721

CVE-2022-48721 affects the Linux kernel net/smc: when SMC is used and a fallback to TCP occurs, some waitqueue entries previously inserted into smc_socket->wq may remain. After fallback, data flows over TCP and only clcsock->wq is woken, so applications (e.g., epoll) may miss wakeups for th...
