Overview
CVE-2026-68345 is a known-severity vulnerability. It was published on August 10, 2026.
Technical description
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->cfg allocated while some
RISes still have ris->mbwu_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.
