"value": "In the Linux kernel, the following vulnerability has been resolved:\n\narm_mpam: Check whether the config array is allocated before destroying it\n\n__destroy_component_cfg() is called to free the configuration array.\nIt uses the embedded 'garbage' structure, which means the array has\nto be allocated.\n\nIf __destroy_component_cfg() is called from mpam_disable() before the\nconfiguration was ever allocated, then a NULL pointer is dereferenced.\n\nCheck for this case and return early if the configuration is not\nallocated.\n\n__destroy_component_cfg() also frees the mbwu_state as this is allocated\nby __allocate_component_cfg(). As the mbwu_state is allocated after\ncomp->cfg is set, and is also under mpam_list_lock, only the first\npointer needs checking."
