CVE-2025-37967

CVE-2025-37967 affects the Linux kernel USB Type-C UCSI driver (displayport) and fixes a deadlock when handling DP Alt Mode. The patch adds ucsi_con_mutex_lock and ucsi_con_mutex_unlock so the connector mutex is only acquired when a connection exists and the partner pointer is valid, preventing a...
