  "details": "In the Linux kernel, the following vulnerability has been resolved:  arm_mpam: guard MBWU state before adding it to garbage  __destroy_component_cfg() adds each RIS mbwu_state object to the MPAM garbage list when destroying component configuration.  However, mbwu_state is allocated per RIS and only for RISes with MBWU monitors. A component can therefore have comp-\u003ecfg allocated while some RISes still have ris-\u003embwu_state set to NULL.  Passing a NULL mbwu_state to add_to_garbage() dereferences the NULL pointer inside the macro.  Skip RISes that do not have an mbwu_state object before adding them to the garbage list.",
