"value": "In the Linux kernel, the following vulnerability has been resolved:\n\niwlwifi: fix use-after-free\n\nIf no firmware was present at all (or, presumably, all of the\nfirmware files failed to parse), we end up unbinding by calling\ndevice_release_driver(), which calls remove(), which then in\niwlwifi calls iwl_drv_stop(), freeing the 'drv' struct. However\nthe new code I added will still erroneously access it after it\nwas freed.\n\nSet 'failure=false' in this case to avoid the access, all data\nwas already freed anyway."

Sin embargo, el nuevo c\u00f3digo que agregu\u00e9 seguir\u00e1 accediendo err\u00f3neamente a \u00e9l despu\u00e9s de que se haya liberado. Establezca 'failure=false' en este caso para evitar el acceso; todos los datos ya se liberaron de todos modos."
