      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nax25: Fix reference count leak issues of ax25_dev\n\nThe ax25_addr_ax25dev() and ax25_dev_device_down() exist a reference\ncount leak issue of the object \"ax25_dev\".\n\nMemory leak issue in ax25_addr_ax25dev():\n\nThe reference count of the object \"ax25_dev\" can be increased multiple\ntimes in ax25_addr_ax25dev(). This will cause a memory leak.\n\nMemory leak issues in ax25_dev_device_down():\n\nThe reference count of ax25_dev is set to 1 in ax25_dev_device_up() and\nthen increase the reference count when ax25_dev is added to ax25_dev_list.\nAs a result, the reference count of ax25_dev is 2. But when the device is\nshutting down. The ax25_dev_device_down() drops the reference count once\nor twice depending on if we goto unlock_put or not, which will cause\nmemory leak.\n\nAs for the issue of ax25_addr_ax25dev(), it is impossible for one pointer\nto be on a list twice. So add a break in ax25_addr_ax25dev(). As for the\nissue of ax25_dev_device_down(), increase the reference count of ax25_dev\nonce in ax25_dev_device_up() and decrease the reference count of ax25_dev\nafter it is removed from the ax25_dev_list."

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ax25: soluciona problemas de p\u00e9rdida de recuento de referencias de ax25_dev. Ax25_addr_ax25dev() y ax25_dev_device_down() existen un problema de p\u00e9rdida de recuento de referencias del objeto \"ax25_dev\". Problema de p\u00e9rdida de memoria en ax25_addr_ax25dev(): el recuento de referencias del objeto \"ax25_dev\" se puede aumentar varias veces en ax25_addr_ax25dev(). Esto provocar\u00e1 una p\u00e9rdida de memoria. Problemas de p\u00e9rdida de memoria en ax25_dev_device_down(): el recuento de referencias de ax25_dev se establece en 1 en ax25_dev_device_up() y luego aumenta el recuento de referencias cuando se agrega ax25_dev a ax25_dev_list. Como resultado, el recuento de referencia de ax25_dev es 2. Pero cuando el dispositivo se est\u00e1 apagando. El ax25_dev_device_down() reduce el recuento de referencias una o dos veces dependiendo de si vamos a unlock_put o no, lo que provocar\u00e1 una p\u00e9rdida de memoria. En cuanto al problema de ax25_addr_ax25dev(), es imposible que un puntero est\u00e9 en una lista dos veces. Entonces agregue una interrupci\u00f3n en ax25_addr_ax25dev(). En cuanto al problema de ax25_dev_device_down(), aumente el recuento de referencias de ax25_dev una vez en ax25_dev_device_up() y disminuya el recuento de referencias de ax25_dev despu\u00e9s de que se elimine de ax25_dev_list."
