      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncan: hi311x: fix null pointer dereference when resuming from sleep before interface was enabled\n\nThis issue is similar to the vulnerability in the `mcp251x` driver,\nwhich was fixed in commit 03c427147b2d (\"can: mcp251x: fix resume from\nsleep before interface was brought up\").\n\nIn the `hi311x` driver, when the device resumes from sleep, the driver\nschedules `priv->restart_work`. However, if the network interface was\nnot previously enabled, the `priv->wq` (workqueue) is not allocated and\ninitialized, leading to a null pointer dereference.\n\nTo fix this, we move the allocation and initialization of the workqueue\nfrom the `hi3110_open` function to the `hi3110_can_probe` function.\nThis ensures that the workqueue is properly initialized before it is\nused during device resume. And added logic to destroy the workqueue\nin the error handling paths of `hi3110_can_probe` and in the\n`hi3110_can_remove` function to prevent resource leaks."

      "value": "En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:\n\ncan: hi311x: corrige desreferencia de puntero nulo al reanudar desde suspensión antes de que la interfaz fuera habilitada\n\nEste problema es similar a la vulnerabilidad en el controlador 'mcp251x',\nque fue corregida en el commit 03c427147b2d ('can: mcp251x: corrige reanudación desde\nsuspensión antes de que la interfaz fuera activada').\n\nEn el controlador 'hi311x', cuando el dispositivo reanuda desde suspensión, el controlador\nprograma 'priv->restart_work'. Sin embargo, si la interfaz de red no había sido\nhabilitada previamente, la 'priv->wq' (cola de trabajo) no es asignada e\ninicializada, lo que lleva a una desreferencia de puntero nulo.\n\nPara corregir esto, movemos la asignación e inicialización de la cola de trabajo\nde la función 'hi3110_open' a la función 'hi3110_can_probe'.\nEsto asegura que la cola de trabajo sea inicializada correctamente antes de que sea\nutilizada durante la reanudación del dispositivo. Y se añadió lógica para destruir la cola de trabajo\nen las rutas de manejo de errores de 'hi3110_can_probe' y en la\nfunción 'hi3110_can_remove' para prevenir fugas de recursos."
