      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware: qcom: scm: Mark get_wq_ctx() as atomic call\n\nCurrently get_wq_ctx() is wrongly configured as a standard call. When two\nSMC calls are in sleep and one SMC wakes up, it calls get_wq_ctx() to\nresume the corresponding sleeping thread. But if get_wq_ctx() is\ninterrupted, goes to sleep and another SMC call is waiting to be allocated\na waitq context, it leads to a deadlock.\n\nTo avoid this get_wq_ctx() must be an atomic call and can't be a standard\nSMC call. Hence mark get_wq_ctx() as a fast call."

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: firmware: qcom: scm: Marcar get_wq_ctx() como llamada at\u00f3mica Actualmente get_wq_ctx() est\u00e1 configurado incorrectamente como una llamada est\u00e1ndar. Cuando dos llamadas SMC est\u00e1n en suspensi\u00f3n y una SMC se despierta, llama a get_wq_ctx() para reanudar el hilo dormido correspondiente. Pero si get_wq_ctx() se interrumpe, se pone en suspensi\u00f3n y otra llamada SMC est\u00e1 esperando a que se le asigne un contexto waitq, conduce a un bloqueo. Para evitar esto, get_wq_ctx() debe ser una llamada at\u00f3mica y no puede ser una llamada SMC est\u00e1ndar. Por lo tanto, marque get_wq_ctx() como una llamada r\u00e1pida."
