"value": "In the Linux kernel, the following vulnerability has been resolved:\n\narm_mpam: guard MBWU state before adding it to garbage\n\n__destroy_component_cfg() adds each RIS mbwu_state object to the MPAM\ngarbage list when destroying component configuration.\n\nHowever, mbwu_state is allocated per RIS and only for RISes with MBWU\nmonitors. A component can therefore have comp->cfg allocated while some\nRISes still have ris->mbwu_state set to NULL.\n\nPassing a NULL mbwu_state to add_to_garbage() dereferences the NULL\npointer inside the macro.\n\nSkip RISes that do not have an mbwu_state object before adding them to\nthe garbage list."
