Short explanation
The iio: accel: kxcjk-1013 driver in the Linux kernel does not filter duplicate event disable requests, which can lead to an underflow of the runtime PM usage count and trigger a warning.
This vulnerability can corrupt the runtime PM reference count through repeated disable requests and cause instability.
What should be done?
- Follow vendor advisories and updates
- Review the relevant kernel patch references
Chain of evidence and sources

Show the technical text from the sources
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.
