  2. Vulnerabilities (CVE)
  3. CVE-2025-21859
In the Linux kernel, the following vulnerability has been resolved: USB: gadget: f_midi: f_midi_complete to call queue_work When using USB MIDI, a lock is attempted to be acquired twice through a re-entrant call to f_midi_transmit, causing a deadlock. Fix it by using queue_work() to schedule the inner f_midi_transmit() via a high priority work queue from the completion handler.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: USB: gadget: f_midi: f_midi_complete para llamar a queue_work. Al usar USB MIDI, se intenta adquirir un bloqueo dos veces mediante una llamada reentrante a f_midi_transmit, lo que provoca un bloqueo. Se soluciona usando queue_work() para programar la función f_midi_transmit() interna mediante una cola de trabajo de alta prioridad desde el controlador de finalización.
