It uses the embedded &#39;garbage&#39; structure, which means the array has to be allocated.</p> <p>If __destroy_component_cfg() is called from mpam_disable() before the configuration was ever allocated, then a NULL pointer is dereferenced.</p> <p>Check for this case and return early if the configuration is not allocated.</p> <p>__destroy_component_cfg() also frees the mbwu_state as this is allocated by __allocate_component_cfg(). As the mbwu_state is allocated after comp-&gt;cfg is set, and is also under mpam_list_lock, only the first pointer needs checking.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>arm_mpam: Check whether the config array is allocated before destroying it</p> <p>__destroy_component_cfg() is called to free the configuration array.
