The query path holds dev_lock and then calls\npm_runtime_resume_and_get(), which waits for the ongoing suspend to\ncomplete. Meanwhile, the suspend callback attempts to acquire dev_lock\nand blocks, resulting in a deadlock.\n\nFix this by releasing dev_lock before calling pm_runtime_resume_and_get()\nand reacquiring it after the call completes. Also acquire dev_lock in the\nresume callback to keep the locking consistent."}, {"lang": "es", "value": "En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:\n\naccel/amdxdna: Soluci\u00f3n para el interbloqueo en suspensi\u00f3n y reanudaci\u00f3n\n\nCuando una aplicaci\u00f3n emite una consulta IOCTL mientras la suspensi\u00f3n autom\u00e1tica est\u00e1 en ejecuci\u00f3n, puede producirse un interbloqueo.
