CVE-2025-37967

In the Linux kernel, the following vulnerability has been resolved: usb: typec: ucsi: displayport: Fix deadlock This patch introduces the ucsi_con_mutex_lock / ucsi_con_mutex_unlock functions to the UCSI driver. ucsi_con_mutex_lock ensures the connector mutex is only locked if a connection is established and the partner pointer is valid. This resolves a deadlock scenario where ucsi_displayport_remove_partner holds con->mutex waiting for dp_altmode_work to complete while dp_altmode_work attempts to acquire it.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: typec: ucsi: displayport: Corrección de interbloqueo. Este parche incorpora las funciones ucsi_con_mutex_lock y ucsi_con_mutex_unlock al controlador UCSI. ucsi_con_mutex_lock garantiza que el mutex del conector solo se bloquee si se establece una conexión y el puntero del asociado es válido. Esto resuelve un escenario de interbloqueo donde ucsi_displayport_remove_partner mantiene con->mutex esperando a que dp_altmode_work complete su ejecución mientras dp_altmode_work intenta adquirirlo.
