Go to dashboardIn the Linux kernel's kxcjk-1013 accelerometer driver, repeatedly disabling an event drops a runtime PM reference that was never taken. This underflows the usage counter and logs a warning.

Systems running a Linux kernel with the kxcjk-1013 IIO accelerometer driver, typically hardware that uses this sensor. The sources do not describe the impact on systems without this hardware, so the rest can likely skip it.

In the Linux kernel, the following vulnerability has been resolved:
iio: accel: kxcjk-1013: reject duplicate event disable
The IIO core does not filter duplicate writes to the event enable attribute. kxcjk1013_write_event_config() already ignores repeated enable requests, but a repeated disable request still calls kxcjk1013_set_power_state(data, false), dropping a runtime PM reference that was not acquired for this request. This can underflow the runtime PM usage count and trigger a "Runtime PM usage count underflow" warning.
Return early when the requested state already matches ev_enable_state.
