"value": "A flaw was found in grub2 where the grub_extcmd_dispatcher() function calls grub_arg_list_alloc() to allocate memory for the grub's argument list. However, it fails to check in case the memory allocation fails. Once the allocation fails, a NULL point will be processed by the parse_option() function, leading grub to crash or, in some rare scenarios, corrupt the IVT data."

Sin embargo, no se verifica en caso de que la asignaci\u00f3n de memoria falle. Una vez que la asignaci\u00f3n falla, la funci\u00f3n NULL se procesar\u00e1 mediante la funci\u00f3n parse_option (), lo que lleva a la comida a bloquear o, en algunos escenarios raros, corrompe los datos IVT."
