"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5: Add a timeout to acquire the command queue semaphore\n\nPrevent forced completion handling on an entry that has not yet been\nassigned an index, causing an out of bounds access on idx = -22.\nInstead of waiting indefinitely for the sem, blocking flow now waits for\nindex to be allocated or a sem acquisition timeout before beginning the\ntimer for FW completion.\n\nKernel log example:\nmlx5_core 0000:06:00.0: wait_func_handle_exec_timeout:1128:(pid 185911): cmd[-22]: CREATE_UCTX(0xa04) No done completion"

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/mlx5: agrega un tiempo de espera para adquirir el sem\u00e1foro de la cola de comandos. Evita el manejo de finalizaci\u00f3n forzada en una entrada a la que a\u00fan no se le ha asignado un \u00edndice, lo que provoca un acceso fuera de los l\u00edmites en idx = -22. En lugar de esperar indefinidamente el sem, el flujo de bloqueo ahora espera a que se asigne el \u00edndice o a que se agote el tiempo de espera de adquisici\u00f3n del sem antes de iniciar el temporizador para completar el FW. Ejemplo de registro del kernel: mlx5_core 0000:06:00.0: wait_func_handle_exec_timeout:1128:(pid 185911): cmd[-22]: CREATE_UCTX(0xa04) No se complet\u00f3"
