CVE-2026-64499

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iio: adc: ti-ads1119: fix PM reference leak in buffer preenable<br /> <br /> ads1119_triggered_buffer_preenable() resumes the device with<br /> pm_runtime_resume_and_get() before starting a conversion.<br /> <br /> If i2c_smbus_write_byte() fails, the function returns the error directly<br /> and leaves the runtime PM usage counter elevated. The matching<br /> postdisable callback is not called when preenable fails, so the reference<br /> is leaked and the device may remain runtime-active indefinitely.<br /> <br /> Store the I2C transfer result in ret and drop the runtime PM reference on<br /> failure before returning the error.
