CVE-2026-90138

CVE-2026-90138 affects the Linux kernel vsock (virtual socket) subsystem . The root cause is that vsock_accept() incorrectly checks the listener socket's sk_err field, which may retain a stale EPROTO error set during a prior failed self-connect while the socket was in TCP_SYN_SENT state. This cau...
