  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: accel: kxcjk-1013: reject duplicate event disable\n\nThe IIO core does not filter duplicate writes to the event enable\nattribute. kxcjk1013_write_event_config() already ignores repeated\nenable requests, but a repeated disable request still calls\nkxcjk1013_set_power_state(data, false), dropping a runtime PM reference\nthat was not acquired for this request. This can underflow the runtime\nPM usage count and trigger a \"Runtime PM usage count underflow\" warning.\n\nReturn early when the requested state already matches ev_enable_state.",
