  "details": "In the Linux kernel, the following vulnerability has been resolved:  arm_mpam: Check whether the config array is allocated before destroying it  __destroy_component_cfg() is called to free the configuration array. It uses the embedded 'garbage' structure, which means the array has to be allocated.  If __destroy_component_cfg() is called from mpam_disable() before the configuration was ever allocated, then a NULL pointer is dereferenced.  Check for this case and return early if the configuration is not allocated.  __destroy_component_cfg() also frees the mbwu_state as this is allocated by __allocate_component_cfg(). As the mbwu_state is allocated after comp-\u003ecfg is set, and is also under mpam_list_lock, only the first pointer needs checking.",
