Answer in brief
CVE-2026-68345 records a Unknown severity vulnerability in arm_mpam: guard MBWU state before adding it to garbage. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
